Re: [Ekiga-list] quick help appreciated: ekiga always report symmetric NAT even after port-forwarding enabled.



I am on a linksys router wrt54g that reports symentric NAT,

What was recommended was to use port triggering as opposed to port forwarding.  I am not too sure what the difference is,  But basically i followed this link ...
