#OPNsense users, it is time to migrate your legacy #IPSEC VPN tunnels to the new connection setup. The Legacy IPSEC feature will be deprecated in 26.1.
I have updated my IPSEC post [1] with the new connection settings. The migration was not straightforward and required some changes, but it is not complicated either.
A little gem here is the #CIDR subnet mask notation used for Policy Based Routing, which allows multiple subnets (#VLANs) on both sides to be automatically routed, without the need for ongoing changes to tunnel settings.
