Hi, there doesn't seem to be alot of documentation on the matter.
We just changed from sonicwall to sophos utm 220.
the toshiba strata unit right now sits in front of the firewall. the wan connection is split using a very small 10/100 switch so that the sophos firewall and the toshiba strata voip sit at the same hierachy level.
ideally, I would like for the toshiba to sit behind the firewall listening on its wan ip (kind of like in its own vlan ). so that I can eliminate 1 extra hop , and remove 1 device from the rack.
meanwhile, the suggested solution they tested out in their lab was to do a bridge connection. but it means deleting all firewall rules/nat rules and doing the bridge over a clean interface.
