Having recently built a new system that runs WInXP, I tried to install and patch OP and run it. Unfortunately, the D2 connection runs into the old "firewall detected" brick wall. I've got a Linksys BEFSR41 router with the old Win98SE system on one line and the new WinXP system on the other. SFC3 D3 runs fine with the proper router port forwarding and no DMZ set. I've tried putting the XP machine in the DMZ, tried various tweaks to the router settings, but nothing works.
If anyone has some tips, I'd appreciate a few. Even if they don't work, it will help me narrow down the possibilities.
Thanks.
