i tried to cinfigure both FWD and SIPGATE to work with uplink but with ni success!! i am behind NAT. i use eyebeam for my SIP calls. should i open any ports on my router ??? thanx !

i try to configure uplink to forward my skype calls to my FWD number. i put in my FWD number and the server, but when i try to register. it gives me an error message that : server fwd.pulver.com did not respont to register (sip:myfwdnumber@fwd.pulver.com) and at the end i get : check server details for that line. i need to mention that i use FWD with EYEBEAM what should i do ??
