[Ekiga-list] Symmetric NAT problem

[Paulo J. Matos]

Hi all,

I have a symmetric NAT problem. I'm living in a student halls
currently and I'm connected to the university connection which
supposedly does not have any kind of firewall. However, during
detection I get a symmetric NAT problem and I cannot even register to
the account in ekiga.net due to timeout.

ekiga -d 4 registers nothing special:
$ ekiga -d 4

Any ideas of what might be the problem?
