IPSEC site to site tunnel between Monowall and Pfsense, rekey-issues
I have som issues with an ipsec tunnel between a Monowall (version 1.33) and a pfsense (version 2.4.3-p1).
The tunnel has the exact same configuration regarding all parameters but for some reason it seems that phase 2 stops working on the monowall side while the phase 2 side on the pfsense seems to be waiting until the next rekey.
If I restart the tunnel or wait for the rekey on the pfsense to be done, phase 2 works again.
Does anyone know the reason behind this or what I can try to do to solve the issue?
you can try what i did on this post and see if it helps to keep your tunnels established. i suspect you have little to no traffic on this link. Don't know if it will help in your particular case... but, i don't see why it wouldn't help a bit:
