(In reply to Andrey V. Elsukov from comment #17)

I have a VTI routed tunnel already to another PF Sense. LAN to LAN, no NAT,
wide open firewall rules. Bi directional traffic. Works fine. 

I was trying to create a second VTI tunnel to a different server, but this one
needed SNAT. It is outbound only. The new tunnel was dropping all replies. I
could see them arrive on the ipsec* interface but they never exited the router
on the LAN interface. 

These sysctl changes allowed the new tunnel to work, but they half-break the
existing LAN to LAN tunnel. Hosts on the "CORE" side where I made these sysctl
changes can still reach systems in the remote LAN, but the remote LAN cannot
access the core LAN. Again, they arrive on ipsec* but they never exit the LAN
port. 

(a) Is there a way to have he best of both worlds? I suspect not. 
(b) Is there a way to configure the old LAN to LAN tunnel such that inbound
traffic will flow again?
