We just tried to setup a UTM 220 as follows and can't ping from the Cisco router to anything on the 192.168.1.0/22 network or visa versa nor can I get to the internet. I can ping the outside interface of the UTM from the router.
UTM inside interface 192.168.1.4/22 (plugs into a switch with PC's)
UTM outside interface 10.10.10.2/32 Gateway 10.10.10.1 (plugs direct to the Cisco 1841 FastEthernet 0/1)
Cisco FastEthernet 0/1 10.10.10.1/32
Cisco BVI 208.x.x.x (external address)
ip route 192.168.0.0 255.255.252.0 FastEthernet 0/1
My router has had 192.168.1.4 on it's FastEthernet 0/1 and it works fine without the Sophos appliance in place for all internet requests on the 192.168.0.0/22 subnet.
I also set an ANY->ANY rule in the firewall part of the UTM.
Can anyone point me to anything I might be missing here? It's a fairly simple configuration.
