The fix is incorrect. Asterisk chan_sip.c must distinguish between
SIP peers that are behind the firewall (together with the *) and those
that are on the outside. Either the configuration flag use_extern_ip
must be specific to a peer, or it must be figured out in some other
way. A global variable won't do since it creates a situation where
either external or internal peers will work but not both.
