I have my UC520 setup behind an SA540 router. The SA540 is at latest firmware.
The UC520 data vlan is 192.168.10.0/24
The SA540 data vlan is 192.168.75.0/24
I have a server in the SA540 192.168.75.0 network as I have it setup for external web access. All of the other data devices are sitting in the UC520 data vlan 192.168.10.0 network. The challenge I am running into is connecting from the server in the 192.168.75.0 network to devices in the 192.168.10.0 network. When I ping inside that network I get a response from the UC outside interface (192.168.75.10) instead of the actual device IP. Outbound from the UC networks are fine including voice which is using a SIP trunk.
I am considering enabling VLANs on the SA540.
