Hi Chris,

there are no worms/viruses on my net. Its a small home network with 
three windows clients and one freebsd server. On that a mldonkey was 
running when the m0n0wall died but I don't think this has something to 
do with it.

My m0n0wall box is a P3 system with two Intel Lan Management Pro 
adapters and 256MB of RAM. I should be able to handle my 1024/128kbit 
DSL line...

Yesterday evening I configured OpenVPN on my box with a client link to 
one of my friends. Maybe that is problem?
At the moment I replaced the m0n0wall box with a lancom 1611 (this baby 
has 66mhz cpu power and 16mb of ram and never died because of traffic).

The output of netstat -m before I replaced it:

$ netstat -m
3943/3968/17856 mbufs in use (current/peak/max):
     3010 mbufs allocated to data
     4 mbufs allocated to packet headers
     929 mbufs allocated to socket names and addresses
388/576/4464 mbuf clusters in use (current/peak/max)
2144 Kbytes allocated to network (16% of mb_map in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines

I am not tied to m0n0wall but would very much like to put it in place on 
a wrap with 3 nics to have my WLAN in a secured area.

I am willing to do a bit of testing. Network debugging is no prob but 
when it comes into kernel tweaks I am a noob. :)
