Asterisk behind 2 different NAT networks

Anyone who has experience with asterisk running on a multihomed platform with 2 different NAT:ed networks? A customer of ours want to connect via NAT:ed VPN

Asterisk 11.8.1

sip.conf:

[context1]
nat = force_rport,comedia
externip = 111.111.111.1111
localnet = 192.168.0.0/255.255.255.0

[context2]
nat = force_rport,comedia
externip = 222.222.222.222
localnet = 192.168.1.0/255.255.255.0

All advices apreciated
Thanks!

If it is really multi-homed (own autonomous system number) that shouldn’t be a problem, as either public address should work.

If it is not properly multi-homed, you may be able to manage by running an Asterisk instance for each public address.

I mean it shold be one asterisk instance. SIP calls should pass from one leg to the other in both directions.
