-nonat only disable trying to find natpmp/upnp stuff at startup. it does not stop protocol specific nat handling (as in mod_sofia) from happening.

Make sure your NAT ACLs and and related settings are correct for your routae networks and you arent forcing some of the NDLB settings on the sofia profiles
