openser is not behind my NAT (see the dump, it has a public IP),
wouldn't that defeat the purpose of nathelper? one of my clients is
behind the NAT, the other isn't. some of the SDP flags appear to be
correct, but I myself am still new enough to SIP that i can't tell what
my SDP flags should be like coming out of the openser box. it appears to
be correct, could you please take a look at the dump and tell me what
specific transactions are causing it to fail?

I'm trying to use openser's (1.1.1) default nathelper.cfg to
connect two
ekiga clients. One is behind a NAT. Both can contact each other,
but the
media streams (neither video nor audio) don't seem to be setup for
some
reason. rtpproxy registers that it should setup the connection, but it
doesn't seem to take off past that.
here's an ngrep dump of the NAT'd client calling the other, and could
appreciate some wisdom on what I need to fix and what the problem is.
thanks.
