Mobile IPSEC connection stops responding after RDP connection initiated
-
Hello,
I recently upgraded our XG-7100G to version 21.02 of pfsense and our mobile VPN seems to be broken. Whether our mobile clients or our windows clients the same symptoms are exhibited. The VPN still authenticates and connects just fine, and if you try to ping clients from a device connected through the Mobile VPN it goes through just fine. However the moment you try to connect to a computer on the network with RDP or browser a file share it completely stops working. The VPN connection itself stays connected, but its almost like the traffic suddenly rejected. Not even the pings will work anymore. If you reconnect of wait five minutes the pings will begin to be successful again. I am not sure what is happening. I double check all my settings, made sure the firewall was not blocking the traffic, I even deleted the mobile VPN and set it up again and it still exhibits the same behavior. I am not sure what to try next so I thought I would ask. If anyone could help me I would greatly appreciate it. Let me know if you need anything else from me. Thanks in advance. -

Update:
So I found this page finally this morning:
https://docs.netgate.com/pfsense/en/latest/troubleshooting/ipsec.htmlThe Connection Hangs section perfectly describes my problem, however I have made many adjustments to the Maximum MSS and have not been able to stabilize the connection. It has improved, but has not gone back to working flawlessly despite trying many values. Does anyone have any advice or insights? Thanks.
