1. The problem is that the outbound interface in a Sun Enterprise 250
running maquerade gets transmit timeouts frequently.
2. I get the error "NETDEV WATCHDOG: eth0: transmit timed out" and a
couple of seconds later the interface jumps back up again. This
seems only to happen after masquerading and packet forwarding is
activated. When i have momentary traffic going in or out (web browsing
for instance) it happens mostly. It does not happen as often when
downloading large files, but will surely happen with somewhat heavy
traffic going in and out for instance while talking on Skype. I tried
reversing the interfaces so that the outbound would be the inbound and
vice versa, mostly to exclude a hardware problem. This moved the
timeouts again to the outbound interface. This was while using kernel
2.4.27. The same problem appears with 2.6.8 and 2.6.15.4 which i am
currently using. Though not as often as with 2.4.27. I have googled
immensely but have only found people with the same problem, no
solutions.

7.7 Interfaces are a Sun Happy Meal and a Sun quad interface.
I will be thankful for any light on this. If i can do anything to help,
i will.
Thanks for your time.
