Hello,

 

I use a ssg5 with the firmware 6.3.0R23.

 

It is not possible to connect to my DDNS Service with HTTPS

I get the error message

 

DDNS: connect error

socket creation failed

 

The root and intermediate certificates are imported.

The connect with HTTP works.

SSG 140 transparent network between multiple VPN subnets

$
0
0

 

Hi Experts,

 

I have some problems setting up my SSG140 to do as I want it to do. Would appreciate if someone can contribute some knowledge and expertise.

 

Current setup:

Server_A - Interface1 192.168.240.1/29

 

-----------------------

SSG140

-----------------------

Multiple VPN clients linked to Server_A

-----------------------

 

Sub1 10.10.1.0/24 tunnel1

Sub2 10.10.2.0/24 tunnel1

Sub3 10.10.3.0/24 tunnel1

Sub4 10.10.4.0/24 tunnel1

Sub5 10.10.5.0/24 tunnel1

...

SubX 10.x.x.0/24

 

Objective:

Open transparent network between subnets. I.e. communication between 10.10.1.0/24 and 10.10.4.0/24.

Preferred is a configuration that allows any traffic between same tunnel but if individual configuration is needed then that is also fine.

 

If anything is unclear please let me know and I'll try to clarify (not an expert on this). 

 

Thanks!

 

Forward public ip to device directly attached to ssg interface

$

0

Greetings to all the experts.

I am a self-taught and I am not much netscreen expert.

 

I have one isp router (A), one SSG140 and one other provider router (B)

 

I should assign 1 Public IP to router (B) directly connected to interface X of my SSG.
Traffic to and from this public IP is going through the provider router (A) connected to interface Y of the SSG.
These are the steps :
isp router (A) > interface Y ssg (n public ip) > interface X ssg > router (B one public ip)
The router B must manage a vpn (for this must have a public ip): I can not use the ssg nat functions.

The solution proposed by the provider of router B requires the use of a switch before of SSG140:
traffic to the public ip assign to router B would be managed directly without going through the SSG.
I do not like this solution and I'd like to handle it with the SSG interfaces but I have no idea on how to make.


Sorry for my bad English (I used the google translator ...)

thank you

wild card ssl cert installation on SSG140

Hi;

 

I have a SSG 140 appliance, and I install a wild card ssl cert (.cer) file to my SSG 140.  

 

1. How can I make it as default ssl cert, whenever I enter https://myfirewall.company.com domain, and I see my cert in CA group, not in LOCAL group, based on my research, my cert should be in LOCAL group, only those root cert, or intermediate cert will be loaded to CA group.

 

2. using this cert as my SSL VPN cert.

 

I can see my certificate load to appliance but when I enterhttps://myfirewall.company.com, I found that it is using self sign cert only.

 

Also, I have a site to site vpn, if I make my wild card ssl cert active, would it break my Site to site link>

 

Please help to solve this issue?

Dears,

 

i would appreciate your help with my case:

 

i have a remote public IP for call manager, i need to grant the PCs on my LAN PCs to access it, so i have added a route and policy to allow the access to that IP, once i configured it on one of the LAN PCs softphone, it got connected for a while then it start to flap between connected and disconnected, ALG SIP is enabled on my firewall (ssg350) , the Public IP is reachable without any issue, i've been informed that the RTP traffic is not reaching the call manager in the remote site, while im allowing ANY ports to towards that IP.

 

could you please share your experience with me so i can troubleshoot the problem.

 

thanks in advance

occasional problem

Hello everyone,

i've a customer who have 2 pair of isg1000 in cluster acting as front and backend for a very big company.

This summer i got a problem on the backend and 20days ago i got the exact same problem on the front end and i don't know how to prevent it to happen again because disservice for this customer is really bad.

 

btw here's the problem:

-we depart in a condition in witch the firewall are normally operating

-suddenly the number of session increase a lot (from 30% of max to 90-100% max capacity)

-traffic remain the same

-studing the logs i found that timeout on primary node for every session is 14x the normal timeout. So primary node is using backup timeout

-firewall is ignoring TCP-Fin

in this condition the sessions do not close so at a point traffic slow down until it stops because the firewall can not provide new sessions.

 

Jtac already got every log i can provide: log,tech support, dump ect

BUT they can not discriminate if it is an hardware or software problem without see the problem in live, but obviusly i can not reproduce disservice intentionally.

 

have you ever got this problems? someone have any ideas?

thx a lot Smiley Happy

ps firewall are ISG1000 with 6.3r21


Where can I find the system logging severity level for each trap message on ScreenOS

I would like to know where can I find the system logging severity level for each trap message on ScreenOS.

 

Following hyperlink describes trap types for ScreenOS. https://kb.juniper.net/InfoCenter/index?page=content&id=KB7990&actp=search

 

But I am not clear which one is critical , Alert, or Emergency. I just know SNMP will only alert on Critical, Alert, and Emergency level messages.

 

For JunOS, I can find them from http://www.juniper.net/techpubs/en_US/junos11.4/topics/reference/general/juniper-specific-snmp-v2-traps-junos-nm.html

 

From above link I know jnxPowerSupplyFailure is Alert and jnxFanFailure is Critical.

 

For ScreenOS, Where can I find the above message?

 

Thanks advance!

SSG140 Different Interface Routing and VLANs

$
0
0

Hello,

 

I have had a couple of SSG140's running 6.2.0r8.0 for a couple of years in a simple configuration, however I need to change this. I am not a CLI guru at all and manage to do everything I need to via the WebGUI, so help using this method would be preferable if at all possible, thank you. Any help from experts would be appreciated. I am sure that what I want to accomplish is not that difficult, however I have not managed to do it successfully myself. The example of what I want to do follows, with changed IP Addresses. This is working from a completely factory reset SSG140 to make it easier.

 

Our data center provider has installed a router and it has 2 interfaces. Interface 1 is for general internet access, setting this up is simple and it works fine. Interface 2 is for accessing servers at their data center, this is what I am battling with.

 

ethernet0/0 - trust - 192.168.100.0/24
ethernet0/2 - untrust - 150.250.120.170/29

 

The above works for internet access with the additional minimal configuration that was required.

 

I have been told by the data centre IT to connect the second cable, from their router interface 2 to a spare port on the SSG, which I have done to ethernet0/4.

 

Their brief instructions:

 

- To access the internet (this I have done, except for the VLAN 200 part which I am not sure if I have to do or not?)
- Set up SSG ethernet0/2 as a routed port with 150.250.120.170/29 (VIP)
- Use VLAN number 200
- Default route to 150.250.120.169

 

- To access the data center (this I am battling with?)
- Set up SSG ethernet0/4 as an internal VLAN access port
- Ethernet0/0 and ethernet0/4 to be in the same VLAN (Trust) segment
- Use VLAN number 100
- VLAN interface 192.168.100.x (x = an unused IP address)
- Add static route to data center 10.200.100.0/26
- Routing to data center next hop from SSG 10.200.100.0/26 gateway 192.168.100.21

 

Thanks,
Paul

I would like to get the number of bits per second(bps) of interface via snmp mib on ScreenOS. I found "ifIn1SecRate" for Junos. But I just found "nsIfFlowInByte" for ScreenOS and I got its value like following. 1.3.6.1.4.1.3224.9.3.1.3.0,nsIfFlowInByte,COUNTER,653321880 What`s the interval of this value(653321880)? How to parse bps? Or is there other OID can do this? Thanks in advance!

Route based VPN - packet dropped, no route - problem

$
0
0

I have two Juniper SSG5 with the same firmware version 6.3.0r23.0.

 

A route based VPN set up between the two that is seemingly working.
SA - status is active and link is up. The tunnel is stable.

 

On both sites:
Ethernet0/0 is the outgoing interface that has access to the internet.
Ethernet0/0 is in the untrust zone (untrust-vr).
The tunnel interface is configured in a zone called VPN (trust-vr) and Ethernet0/4.
The zone named Config (trust-vr), configured on both sites is what the VPN shall interconnect.

 

SiteA
Ethernet0/0 is configured with a Static ip
Ethernet0/4 10.1.1.0/24
The tunnel interface is named tunnel.1
Config zone 10.238.135.96/24 GW 10.238.135.97 (manageable)

 

SiteB
Ethernet0/0 Dynamic IP behind a NAT
Ethernet0/4 172.16.10.0/24
The tunnel interface is named tunnel.2
Config zone 10.238.135.128/28 GW 10.238.135.129 (manageable)

 

 

I have followed a KB article (KB15075) to configure Route Based LAN to LAN VPN using pre shared secrets to remote site with dynamically assigned IP addresses.

 

I don’t have any hosts connected yet so I am only trying to pass traffic between the gateways and I am testing with http/https between the sites.

 

The problem I am having is that I get a “packet dropped, no route” on the other site when trying the access it’s gateway.

The below logs is from when I from SiteA, using http, to SiteB’s gateway, 10.238.135.129, from a laptop with IP 10.238.135.101.

 

The packet got all the way to SiteB, but is dropped because it cannot find a route.

As you can see below there should be a route, if I understand correctly there is no route loops.

I added the debug log from SiteA too at the bottom of the post.

 

The problem is the same both ways.

Could anyone help me shed some light on this, what is causing the “packet dropped, no route”?

L2TP over IPsec to Microsoft RRAS

$

0

I have a Routing and Remote Access Server behind my SSG and I would like to use it for L2TP VPN. When I try to forward UDP 500 using VIP on my interface, I get a message saying it's not supported, 500 is for management of the box.

 

I'm also currently using site-to-site VPN which I imagine is using port 500 on the same interface. Is this what is stopping me?

 

Would there be any way around this? My goal is to allow clients such as Windows PCs and iOS devices to connect to my network without using a certificate and instead a preshared key -- which RRAS supports.


Remove a VPN Tunnel

Hi,

 

I 'simply' need to remove a VPN tunnel from my SSG 140 firewall.

 

When I go to the VPN>Auto Key and hit rrmove on the tunnel I need to delete, I get the following message...

 

This VPN has tunnel interface binding. Please remove the binding first.

 

I've tried going and unbinding the interface but it;s alerady ser to none.

 

I'm, really stuck, don't want to remove anything that will break existing tunnels.

 

Any help will be greatly apprecuiated.

 

PS. Don;t ask me to go into the CLI, I'm not that confodent with the CLI and worry I'll break something else.

 

Manuy Thanks,

0/0 Trust Network = 192.168.1.254 

0/1 DMZ network = 10.1.1.254

Actual trust network IP device=192.168.1.10. I want to map this IP to 10.1.1.250. So my device in DMZ can ping 10.1.1.250 which are refering to 192.168.1.10 host.

Appreciate any advise.

SSG5 Performance Issues

Hello New to the foruma.  I have issue when trying to transfer larger files like 2 to 3 Mbps through different zones in the SSG5.  I did a get inter eth0/3 and see below it shows a half-duplex connection.  What is really weird is I dont see any collisions on the interfaces just bad performance.  I am connecting to a HP HP V1910-48G Switch.  I am pretty sure that the performance I am getting when copying between zones is from the half duplex..  My transfer rates are like 300Kbps but if I dont go through the firewall and both devices are in the same zone it is lighing fast.  Can anyone help should there be collisions that show up?

 

Interface ethernet0/3(VSI):
description ethernet0/3
number 7, if_info 2856, if_index 0, mode route

Hi,

 

I about to configure PBR on my customer ssg550 production device,

Thank you
