Configuring network interfaces

[Richard Barraclough <richard@sigma.ndo.co.uk>]

Dear all,

I'm trying to change the configuration of my network interfaces but I'm
having trouble with dhclient overriding my settings and with disabling
masquerading and ipchains.

Original config:
eth0 static ip address
eth1 address obtained via dhcp
Network on eth0 is masqueraded to eth1

What I want:
Both static IPs with no masq/firewall

Problems:
I set /etc/networks/interfaces but dhcp seems to override it
Is it possible to disable dhcp without un-installing it?
On reboot the firewall (ipchains) is always reset to the masquerading
config. How do I get it to stay how I put it?

Thanks,
Richard.
