One possible reason is a broken firewall on the server side which blocks all ICMP messages, including those used for Path MTU discovery (fragmentation needed, but DF bit set). I have no experience with ethernet over firewire, but if it uses an MTU smaller than 1500, this misconfiguration on the server side will cause you problems. You could of course deactivate PMTU discovery locally, but if it is active on the server side, together with this strange firewall setup, all you can do is complain to the server operator. If you can live with just web access and without full IP connectivity, I would suggest you set up a proxy on a machine that doesn't show these problems, and configure your Mac client to use this proxy.
