Need to configure XB7 gateway to allow L2TP/IPsec VPN.

Very interesting since it used to work until I upgraded to th XB7 gateway.

Unfortunately, we do not have that feature on these modems, but you are able to set up bridge mode so that you can make your adjustments.

I tried an XB8 and it didn't work either.  Purchased a TpLink router and placed Gateway in Bridge mode.  Should then be a piece of cake but it has me pulling my hair out.  Can't get bridgemode to talk to the router.  It recoginizes the cable but no internet connection.

Experimented today with bridge mode to see which LAN ports were functioning.  Just wanted to verify I was connected to a live port on the gateway.  I was able to ping the gateway on all 4 LAN ports while in bridge mode until I powered off/on the gateway.  After power reseting the gateway, I lost my ability to connect.  Multiple computer reboots and several gateway reboots failed to resolve anything.  I was could not connect to the gateway and had to call customer support and have them take me out of bridge mode.  The customer support agent was able to get me out of bridge mode but that was as his technical competence went.  Fustrated.

Thank you for sharing your experience with testing out those ports, are you trying to enable the bridge mode again on your gateway now?

There isn't a solution.  My internet connection was reconfigured slightly to account for the use of my modem but my issue with the VPM is unresolved.  It's not Xfinity's issue so it must be someones else's problem.

I wasn't really surprised.  Everything I could find said it won’t fix my problem.  I was just kind of praying for a miracle.
