Lost connection

[Marc Levesque <mlevesqu@licef.teluq.uquebec.ca>]

Hi all,

I have an openbsd who act as a router between 3 networks:

NICS: 
1 Syskonnect SK9481 (1gbps)
2 3Com Server Card 3C905C (100Mbps)

I use a GENERIC kernel version 3.0
recompile with this option:  NMBCLUSTERS=8192

When people connect from the syskonnect LAN, after a small period of time,
the connection are dropped !
On the other side, peoples from the 3Com LAN, seems to work well !
I use PF too !

Do I need to increase the NMBCLUSTERS ?
Any other suggestion for optimizing openbsd for routing ?

thanks
Marc
