After the resident router broke in our small office, I installed a WRT54GL with Tomato as a replacement, and it's been working great except for this one thing: I can't for the life of me access a desktop remotely through WAN. I've been using the standard Windows RDP client, which I'm told worked before the router switch (no pun intended), and I have forwarded port 3389 is forwarded to the correct computer, and I've ensured the computer is listening for RDP connections on that port. I've tried enabling DMZ for the target computer, and I've disabled and even uninstalled its software firewall to no avail. RDP works fine via LAN, though, for some reason. Does anyone know what could be the issue here?
