Here is what I have, a SPARC 5 running Debian Woody, 2.2 kernel since the
2.4 is not stable, and a single NIC. I have Alias the NIC for two addresses.
This box is an internal router for a small network. The interfaces file
looks like:

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
auto lo
iface lo inet loopback

# The first network card - this entry was created during the Debian
installation
# (network, broadcast and gateway are optional)
auto eth0
iface eth0 inet static
 	address 192.168.1.1
 	netmask 255.255.255.0
 	network 192.168.1.0
 	broadcast 192.168.1.255

auto eth0:1
iface eth0:1 inet static
	address 10.0.0.1
	netmask 255.255.225.0
	network 10.0.0.0
	broadcast 10.0.0.255

I am trying to setup some IPChains to do the routing. I have tried the
following:

ipchains -A forward -s 192.168.1.0/24 -j MASQ
ipchains -A input -s 192.168.1.0/24 -d 0.0.0.0/0 -j ACCEPT
ipchains -A forward -s 192.168.1.0/24 -d 10.0.0.1 -j ACCEPT
ipchains -A output -s 192.168.0.0/24 -d 0.0.0.0/0 -j ACCEPT
ipchains -A output -s 10.0.0.1 -d 10.0.0.254 -j ACCEPT
ipchains -A input -s 10.0.0.1 -d 0.0.0.0/0 -j ACCEPT
ipchains -A forward -s 10.0.0.1 -d 10.0.0.254 -j ACCEPT

All I can do is ping the interface card. I can use either address,
192.168.1.1 or 10.0.0.1, but I can not ping the DSL router on the other side
of the box, 10.0.0.254. What am I missing to get IPChains to route on this
single NIC?

I have IPChains version: 1.3.10, 1-Sep-2000 and Kernel version: Linux Router
2.2.20 #1 Fri Nov 16 15:48:02 EST 2001 sparc unknown.

Any ideas what I am doing wrong?
