Another Routing Question

Hi All,

I am trying to route between to firewalls that are directly connected. I am using one firewall as my perimeter and the other astaro as my dmz firewall. I believe I may have my masquerading rules wrong.

so for example, lets say I have a 172.22.1.0/24 network behind the DMZ firewall and a 10.0.0.0/24 network behind my perimeter firewall. 

Normally I would just create routes on my palo alto firewalls to accomplish this and they talk fine. 

How would I accomplish this on the sophos firewalls? do i need a proxy arp on the 172 interface and static routes and firewall rules? 

Any help is greatly appreciated.

  • Why do you want to use 2 firewalls? I suppose the UTM could handle it alone if you'd like.
