Router With Hl Problem

[holy_devil]

:help:
my netgear router keeps dropping my entire listen server(haven't tried dedicated, assuming it will be the same outcome) at seemingly random points, i believe by changing the port my hl client is sending out. if i do 'status' it says 27015, but its never my ip:27015 to find it, i think thats sven though :p

when it drops everyone, they all time out and i'm left unlagged etc, i've turned off my xp firewall and opened the 27015 port, not sure what to do at this point its not my isp or anything either, been through two isps with this problem. any help appreciated, i've looked at netgears site some but theres never anything useful there  

thanks in advanced  <3
