netgear rp614 server hell

Hi All
this is doing me head in now. have got one server running bhd and one pc attached to a netgear 614 router. my connection is with telewest blueyonder on a 2mb connection. Sometimes i can get into the server to play and sometimes i cant but no one else is having problems getting onto my dedicated server. i have tried port forwarding and other people can get on either with port forwarding running or not running but makes no difference to me not being able to connect. the only time i can connect is if i power down the router and power it up again. lol its my server and im the only poor bod that cant get on. PLEASE PLEASE HELP
