Firstly... sorry to those of you on both the netfilter and lartc list who''ll end up with this message twice... I am trying to find out what kind of latency I can expect when dNAT''ing UDP packets on (probably) a mid-range P3 server, 32-bit 33MHz PCI bus with Intel EEPro NICs. It''ll most likely be running whatever the latest 2.4 kernel will be at the time, unless there are significant boosts in packet mangling performace in 2.6. Sorry that this is such vague set of specs, but this is just a vague idea at the moment. Any suggestions for hardware that would be particuarly suited to shifting packets with the lowest possibly latency would be much appreciated. cheers. Jamie... PS Thanks to the Netfilter team for producing such a cracking frame work, thanks to the LARTC guys for making me feel like a newbie again :) -- ** This message was transmitted on 100% recycled electrons ** _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

Some of the traffic will be going to/from game servers so latency can become noticable. cheers Jamie... -- ** This message was transmitted on 100% recycled electrons ** _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
