Forums Connection Issues Linksys Router and DCC Sending???

i checked the DMZ settings, and the local IP of this machine is already set there =(

my brother keeps insisting that it's not on my router settings because were on DHCP, he says that since all of the ports are open and because we're not on Static, it should already be working. he says it must be on my mirc settings, but i've already checked them, and they seem to be as they should. i don't know what else it could be... does anyone out there have linksys router who's got no probs DCC Receiving AND DCC Sending??? if yes, please enlighten me on how to make mine work please, because this is getting quite frustrating

thanks =)
