[Freeswitch-users] NAT port problem

[Brian West]

In this case its probably not an ALG, you should enable rport in your
device and NOT force it with the NDLB param, if your device doesn't support
it, throw that device in the trash or take a hammer to it, and buy a device
from a manufacture that actually made an effort to implement SIP.
