If you have issue like this. Change virtualcoin.conf "port=30000
But even in that case, I suggest create port forwarding rule to allow traffic.
Outside port TCP 443, inside port TCP 30000 & your PC's IP address.
Agree, if you want to support & allow office users behind corporate firewall, we have to use either port 80 or 443. Most work PCs run 24x7, that will provide VirtualCoin network stability also allows users from office to mine coins as well.
