[Linphone-users] linphone access when a firewall is involved...

[William Bulley]

I have installed linphone 1.3.5 on two FreeBSD 6.1 machines
and demonstrated that it works as advertised on my local
(private) LAN between those two systems using non-routeable,
RFC-1918 (net ten) IP addresses.  When I try to use linphone
across the Internet to another FreeBSD 6.1 user also running
linphone 1.3.5 (both of us have firewalls), it does not work
as advertised.  We are able to connect using SIP and to chat
in the chat window (ASCII text only), so I do know that both
linphone configurations are correct at least for SIP.  However,
no RTP audio works between the two instances: my local linphone
and the remote (to me) user's linphone.

Both of our firewalls have been configured to allow inbound
access from any source to our local LAN machines for both
the SIP protocol (on TCP port 5060) and the RTP protocol (on
TCP port 7078).  Since the complete linphone application is
known to work on my local LAN between two local machines, I
am suspecting that something is amiss with the configuration
of the firewall on my end or the firewall on the other end.

I can give further details of my firewall setup if needed,
but I thought I might ask here first if there is something
else that I need to check.  Maybe I am missing something
obvious (but not to a new user of linphone) that is simple
to correct.  Thanks!
