My friends and I are having issues with TWC in regards to XBL or more generally port access. Everything used to work but recently stopped.
I am wondering if anyone else on TWC is having similar issues (as described below) and if so what if anything they have done to resolve them.
Where: US -> California -> San Diego
Modem: Motorola SB5101
1.) We are not able to join an XBL party hosted by any of us (3 people each on TWC)
2.) We are not able to join each others games (ex. Borderlands2 -> connection to host failed)
3.) If another person (non TWC) hosts an XBL party or BL2 game we can all connect and play
What we tried:
1.) Tried checking router WAN IP vs internet IP described here (http://forums.xbox.com/xbox_forums/xbox_support/xbox_one_support/f/4267/p/1667262/4400402.aspx)
both IPs matched
2.) Two of use tried direct connecting our cable modems to the XBOX to rule out any router issues:
Connections still failed
3.) We setup a webserver and forwarded several ports (3074,88,80,etc) to the webserver:
From outside TWC (cellular network) we can see the webpage
From inside TWC the page is not reachable
4.) Spoke with level 2 TWC support. He indicated, TWC does not block ports, since I bought my own equipment (modem/router), they won't troubleshoot anything. More specifically, even if I did buy/rent my equipment from them, there isn't much they would do other than confirm my router config was correct and send some signals to my modem.
Any ideas/suggestions/insights would be much appreciated.
