Hi, I have recently bought Inca AMX-CA81R, and wanted to open port 6112 for listening in order to host online games. But when I try to do that it wants me to enter my IP number. No problem until there. But when I click "Save Settings" it says "Modem must be rebooted." OK, but when modem reboots it gets a new IP number and the one I entered becomes useless. A solution I found is to get a static-IP but thats like $20. If I knew how to shut down the firmware firewall... Thank you.
