Jason - easy solution. Just use the "use this device name" and add a FAKE MAC address. Then it will never change. The issue is when you use the NIC card (physically plugged in) locally on the uc500 vs. the wireless NIC card (when you use the wireless to get internet) vs. the VPN client (when you use either with a VPN client) you can get different MAC addresses assigned for each. If you do things this way, it will work just fine. Use the format SEP(MAC ADDRESS) (Example: SEP002215260FD4) under the ipcommunicator settings.
