IPSEC VPN with Draytek Router
-
Hi,
We have been running a IPsec VPN for years with no problem. since the latest Pfsense update, after a few days the VPN stops passing data yet the connection remains active.
so far the only way to get it working again is to reboot the pfsense box. then it works fine again for a few days before the problem happens again.

Hi,
I have a little different problem sinds last update.
The connection betweeen the Pfsense and Draytek 2960 drop every 2-3 munitessinds last update.
Also tried lowering MSS clamp, but that did also not work. -
I think i have found the issue.
Default in IPSEC / Advanced Settings the option Configure Unique IDs as is set to yes
changed this to no and restarted the VPN and now traffic is working again. previously with Configure Unique IDs as set to yes the only way to get traffic flowing again would be to reboot the PFsense box.
