[SR-Users] Incorrect IP address in path header

[Daniel-Constantin Mierla]

Hello,

is kamailio listening on both externalip and internalip? Do you have ip 
routes from externalip to FS ip?

You can try with mhomed=1 or force the send socket with 
force_send_socket() or assignment to $fs.

Cheers,
Daniel
