pfsense IPsec phase 1 disable rekey

pfsense IPsec VPN tunnel disconnects after 8 hours

I’ve been troubled by the annoying disconnection of the IPsec VPN tunnel on a pfsense firewall. The tunnel disconnects after about 8 hours.

The solution in my case was to enable “Disable rekey” which “Disables renegotiation when a connection is about to expire.“. The setting is found under Phase 1 advanced settings.
