WireGuard with Xfinity xFi Modem

Is anyone having issues running WireGuard with Xfinity?

I have a RP3+ with PiHole and WireGuard. Connected to a PoE switch that sits behind my Asus Router (Most up to date AsusMerlin Firmware).

Originally I thought I was having an issue with Port Forwarding on the Router but now i’m starting to think it’s Xfinity prohibiting the traffic. All Port Forwarding was originally set up using the Web GUI, then I tried it with the jff scripts/IPTables. Still no go but I’m not sure if it’s the Router or Xfinity Modem.

App on iOS shows connected but there’s no network connectivity after that connection. I’ve disabled the Advanced Security on the xFi Router/Modem as well which seemed to work for some but not others.

Any suggestions would be greatly appreciated.

Since you are using your own router I’ll say the problem is on your end. I use WG with Xfinity and there aren’t any issues. Just make the WG device IP static (probably already static if using PiVPN) and simple forward the port (default is 51820) to that IP. If you were stuck using their rented equipment with their dumb mobile app configurator then maybe it would be something on their end to protect users from themselves.

Yeah that’s what I was thinking as well. I just know Comcast did something awhile ago and it screwed users with OpenVPN. Thought maybe it was a similar thing. Thinking it’s my router just not forwarding correctly even tho everything looks 100%. Thanks for your comment.
