Logging dropped packets

Hi

I want to see if my linux box is dropping packets for some reason. There is
no firewall running, but a remote (VPN) user cannot access our MRP system.
tcpdump shows me that a few packets are exchanged before the client gives
up.

How can I switch on some very detailed logging and view the results?

Thanks
Tim

I would advise to use iptables (or whatever) to just log any packet
arriving to the machine

example:

iptables -A INPUT -j LOG --log-level info \
--log-tcp-sequence --log-tcp-options --log-ip-options

you might want to add this for OUTPUT as well.
