I just replaced my sonicwall with a sophos utm 220.
Currently sophos device and toshiba voip are behind a linksys 4 port switch at the same hierachy level.
the toshiba strata cx670 listens on a wan ip.
I specifically asked if I can have the toshiba strata listen on a lan ip and I configure nat etc.. but the vendor specifically said
"For your info, voice communication systems should not be blocked by firewall. Hence, the Toshiba system has to sit before firewall, using WAN IP."
(as a matter of fact, previously on the sonicwall, we tested and it failed)
I want to check and see if the sophos utm 220 can put the toshiba voip plugged into eg: eth7 , yet have it bypass the firewall/nat altogether (ie: the toshiba voip still listens on its wan ip). that way I can eliminate 1 extra device on my network
See attached pictures. thanks
