even with fibre your consumer router will probably have a limit to how many connections/sessions it can handle.
it will beable to handle the bandwidth but the connections/sessions are a different story.
for example, my home ADSL router has a 533MHz cpu that the manufacturer rates at 300,000 connections/session. (thats probably them being either optimistic or what the cpu takes before its reaches 100%)
even then I still impose a limit on the router at 16834 connections that way the routers cpu has plenty of overhead.
so first of all check that the router isn't being bottlenecked. if you think it is then it might be a good idea to play about with UDP timeout settings to strike a better balance at when the router drops expired UDP connections.
secondly are you hosting the servers from a client OS such as windows XP/vista or 7? or a server os such as windows server, osx server, or linux?
Is the pc dedicated to only hosting the games or are you also gaming from the same pc?
whats the specs of the PC hosting the server?
Its hard to help since I havent experienced this myself, my regular ping to my own server from my crappy 4meg adsl is 48ms in game, and even during drdos attacks it remains at 48ms.
infact the only way i know my server is even involved is when I see my servers bandwidth stats are slightly higher than usual lol.
Hey Nitro,
When I experienced the high pings on my system, (by the state of the investigation) the attack was so intensive, that it total burned the CPU of my firewall.
I will replace my current firewall to one other, although its software remains the same: PF Sense. Currently it runs on a virtual PC but the new will be a dual core s1155.
So yes you are right, my firewall was too weak to handle the attack.
My question was why am I attacked and meanwhile other server owners not complaining on lags, invalid UDP attacks, huge traffic, etc?
So the high pings of my players was because of the massive network traffic, and not the weakness of the urt hoster computer. BTW you asked about my hoster: I have Ubuntu server version 10.04 LTS (virtual on ESXi).
On this I didn't experence high CPU usage, or run out of resources.
Thanks BB:
