Re: 2.4.6pre iptables masquerading seems to kill eth0

[Thomas Weber]

I'm on 2.4.6pre3 + freeswan/ipsec on my gateway now for 5 days.
It's an old 486/66 32MB with several isdn links, a dsl uplink (with 
iptables masquerading) behind a ne2k clone and a 3c509 to the inside network.
no problems at all with the interfaces (all compiled as modules).
