Otherwise, you're right... other than that, you don't need any forwarding at all. If you're still dropping calls, the culprit is that asterisk is never receiving confirmation from the remote phone. Double check your rules and routes, it's in there somewhere! Hey there,

If you’re still dropping calls, the culprit is that asterisk is never receiving confirmation from the remote phone. Double check your rules and routes, it’s in there somewhere!

I just verified this with a switchvox, simple ipsec between 2 fortigate 60Bs, and some tcpdumps. With localnet settings, packets never hit the wan1 of the fortigate, without them, it hits wan1. I however, still have calls dropping at 20 seconds for some reason. Actually, the port forwarding shouldn’t be necessary if you have your localnet settings.

Don't want too much exposure. Can you talk about specific about ports and rules while remaining firewall-agnostic? (In other words, I don't have a Fortigate!)

Adding the localnet parameter was just what I needed to do to get this working! Thanks. Adding the localnet parameter was just what I needed to do to get this working!
