Warcraft III Router Problems


I know this question has been repeatedly asked (with as many routers as stars in the universe), but I cannot host Warcraft III games or create teams. I have a D-link 614+ router (research tells me this is the problem), so I went to Blizzard's support site and went to the D-link support section. I completed the instructions and filled out the Advanced section of the D-link support site, but it said that there is a "port range conflict." I still cannot host games. Any help on this particular router subject?
