The problem comes here: if I 'ping' between these two machines,
everything is fine, but if I 'ping' with a packet size of, ie, 2000, no

packets? Do I have to include any other rule for dealing with fragments?

Does this not effectively kill all frags? Are your unreceived packets
showing up in the log? And if not, are you sure that it's BSD4 that's
losing them, and not ubuntu3?
Here's how my firewall handles frags:
# Allow IP fragments to pass through
/sbin/ipfw add pass all from any to any frag
You may also want to set up something similar to handle ICMP.
I've not used dummynet pipes in ages, I wonder if setting a larger queue
would help with my disconnect problems, or whether I really do just need
to give up and reinstall the entire OS.
