VPN, Static IP, and ConnectionPro
I have a Ubiquiti USG-4-Pro firewall that I am unable to establish a VPN connection to after moving to a static IP. I am not certain if my Comcast Modem is configured in the proper way and need some assistance to verify the proper configuration is in place. The Comcast modem is inline with a ConnectionPro Cradlepoint LTE device which then hits WAN1 on my USG. From what I'm gathering, the combination of having a static IP and disabled bridge mode is likely the problem. Is there any way to make this work and keep my static IP? I'd really like to get back to VPN'ing successfully into my home network while I'm traveling.
As an experiment, I moved to a block of 5 static IPs to try a direct connection from one of the business gateway's LAN ports to WAN2 on the USG. I'm reading conflicting success stories for L2TP VPN on WAN2, so I'm willing to forget that idea and just use WAN1.

Hello and thank you for taking the time to reach out to us here on our Comcast Business Forums. Just to clarify, have you been able to connect to the VPN with the Ubiquiti USG-4-Pro firewall prior to having a static IP? Or is that equipment new to your set up as well?

Thank you for the reply. It was working prior to the introduction of the static IP. I think the LTE modem came along shortly thereafter.

Thank you for that information. I want to make sure my understanding of what happened is solid. Your VPN worked until you added a static IP block to the account. After that, and prior to the new LTE modem it stopped working? Just to clarify, the modem you are referring to, is it equipment you purchased or we provided?

Sorry, I should clarify.
I lease the Comcast Business Gateway TECHNICOLOR CGA4332COM.
VPN worked well as long as I checked my public dynamic IP occasionally before connecting.
I moved to a static IP and added the ConnectionPro Cradlepoint E110C4D.
At that point, VPN would no longer work.
