Go through the "connection probs - check here first" link too... it's got heaps of info about connection/firewall probs.
Don't use 2 software firewalls. Pick 1, configure it for LW & disable the other one. If you tried manually port forwarding, did you set up a static IP address first? Were you using instructions from this site?
