I have been struggling with this since we got it all installed. We recently got cable TV from Wave cable, and they gave us An ARRIS setup. Including this *Lovely* MG5225G/NA gateway, the gateway is what is giving me the troubles. We have a linksys e2500 router connected through the gateway, and all of our devices connected through the router. I have been going back and forth with the router and gateway trying to get ports to work, And they worked fine back when i was just using a modem to connect to the router. Between me and my friends i am the one that host all of our servers, Killing floor, mine craft, hamachi LAN parties, and so on. Since this setup was installed i have been unable to get any ports to work and am in need of desperate help. Also when connecting to the gateway via chrome with 192.168.0.1 the interface allows me to search through the tabs, but it wont let me change any settings. When i hit apply to the settings it does nothing and reverts them when i refresh the page.
