Both firewalls are connected back to back with same security level (60). - DMZ interface
Both firewalls run ospf and default route is injected by firewall 1 to firewall 2 (dmz interface) and l3 switch - which is all fine. I can see the ospf routes but when i try to ping outside world from Firewall 2 through to Firewall 1 on dmz interface i cant seem to get a response although from L3 switch i can ping outside world ?
I have tried adding same-security level permit inter interface traffic (or something similar) on both interface of the firewall but no joy. any thoughts please ?
