Ok, the Port Forwarding thread is there, I know, but it does not really help me, because I have no router. I have a cable from my computer to the modem(Westell Model 2200), then from the modem to the phone.(not dial-up) I gave blockland complete access, and even with the firewall off I cannot make a server. I followed the very last step on the Port Forwarding guide, and have the same exact numbers, except for the ones that are mine.
I am good at several things; Internet connections, is not one of them.
