Hello,
I'm having a few issues setting up proxy ARP and DIP on a SSG firewall - (Error message is attached) It is complaining about the fact the interface has an IP in a different subnet than the proxy ARP range - This is correctly as there is a 'transit lan' range between the firewall and ISP Device but the source NAT range is in a different subnet.
I know this can be done as I have this configured on our SRX firewall but obviously i'm missing something here :-)
Many Thanks!
