Re: Using shorewall

Yeah, you need to update /etc/network/interfaces to reflect each nic. You might also want to read ch10 of the ref guide.

My /etc/network/interfaces file reads: >  > # This file describes the network interfaces available on your system > # and how to activate them. For more information, see interfaces(5). >  > # The loopback network interface > auto lo > iface lo inet loopback >  > # The primary network interface > allow-hotplug eth0 > iface eth0 inet dhcp

add something like this to /etc/network/interfaces after the last line there (and maybe drop the hotplug from eth0)

# The dmz zone network interface on eth1
iface eth1 inet static
             address 192.168.0.111             ---- or whatever your address will be
             netmask 255.255.255.0
             gateway 192.168.0.1

# The local zone network interface on eth2
iface eth2 inet static
             address 192.168.2.1             ---- supposing this would be your internal gw
             netmask 255.255.255.0

Then you will have to make sure your routes and nat are correct. Now I don't know if you need gateway address set for interfaces that are on the inside or not.

Also, if your new to networking config, try Webmin. It will make things easier. (ok thats 2 plugs, no more)

I have set up shorewall with eth0 going to my existing d-link router. eth1 and eth2 are planned for a dmz and a loc. I have used the setup and     

 what's your final /etc/network/interfaces ? what do ifconfig(8) or ip(8) report?    

lines from /var/log/shorewall-init.log):  Setting up masquerading/SNAT....   ERROR: Unable to determine routes through interface "eth1"     

 perhaps some more log line would help ? ...
