Server stand behind nat without having to configure ports forwarding.
Ports 5500 .... 5900 etc. are closed.
PCHELPWARE or SCIII server behind NAT can't connect to repeater.
(This same server no stand behind NAT can connect to repeater)
Is possible connect server behind NAT to repeater without forwarding ports using UVNC addons?

Server behind NAT
Re: Server behind NAT
where is the repeater ?
if repeater is on your lan (internal), you still need open port for allow incoming connection from WAN (external, internet)
but if you use public repeater, don't know where is the mistake
since there a lot of users use SC, pchelpware of public repeaters
the most known and working pchelpware and public repeater is:
http://vserver.homeftp.org/en/remote.html
follow the basic rule and have nice fun
