-- r u using PPPOE through XP or r u using the modem's internal PPPOE?
if u're using the modem's internal PPPoE then u can't port forward... which means u can't CS.
But if u dial PPPoE through XP then u can..
--I'm not sure,maybe it's the first case(PPPOE through XP)--wt should I do 2 let people see my server on the list and join?
