how did you check if it's working or not?
netstat -na | find ":7" | find "LISTENING"
if you see 7000 7100 7200
next is to check if you can connect to yourself. Gate should show connect/disconnect.
telnet 127.0.0.1 7000
telnet 127.0.0.1 7100
telnet 127.0.0.1 7200
if you see blank screen, it works. to exit telnet, Ctrl-] and then type quit
now ask a friend to do something similar
telnet netip 7000
telnet netip 7100
telnet netip 7200
replace netip with your real ip.
if it's still not working...
I suggest you post all the screenshots...
windows firewall, exception list,
router port forwarding page, etc...
