I have bee fighting with an obsure issue for the past 48 hours.
Essentially I have two routers
These boxes then have a floating WAN address of:
Now… the floating ip range has 13 vpn tunnels attached to it.
For months this has worked absolutely fine - but recently for no apparent reason the vpn tunnels have stopped working.
I have tracked the issue down to the fact that despite the tunnel being bound on the 18.104.22.168 address. When the tunnel tries to connect it does so on the 22.214.171.124 or 126.96.36.199 address.
The net result is my tunnels are fail.
Does anyone have an idea how to fix this issue?
