I am having a similar problem. Although, my config is MUCH SIMPLER! As Jason Nickle pointed out, only VLAN 1 (for data) and VLAN 100 (for voice). I have the UC320 set up as the EDGE device in my customer's network. I am trying to do some very simple port forwarding to a Cisco SF308 Managed POE switch. However, it's not working. The basic idea is i'd like to be able to manage the phone system and the switch remotely. I was thinking something like 199.7.199.x:8080 for the UC320 and then port forward 199.7.199.x:8090 to the switch @ 192.168.24.2 on VLAN 1. The switch is set up properly as i can http to it just fine on the LAN side. Any thoughts?
