https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=248474 jeremy.mordkoff@riftio.com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jeremy.mordkoff@riftio.com --- Comment #35 from jeremy.mordkoff@riftio.com --- (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? -- You are receiving this mail because: You are the assignee for the bug.
