OK, I'm trying to set up IPCop (using it as a good NAT firewall and proxy) here. I have a block of IP's from my ISP and a DG814 so, using these together I thought I would be OK. Here is what I was wanting to do

DG814 <-------> (eth1) IPCOP (eth0) <--------> LAN (192.168.0.x)

Now, we are given the IP range xxx.xxx.207.128-xxx.xxx.207.143by our ISP with the Subnet Mask of 255.255.255.240. The DG814, however, usually picks up a different IP address, this being xxx.xxx.147.222! Should it do this? To try what I was doing, I gave the DG814 the LAN IP of xxx.xxx.207.129 (in my allocated range?) and the subnet 255.255.255.240. I then gave eth1 on the IPCOP box the IP xxx.xxx.207.130 and the subnet 255.255.255.240 although this then seemed to think that xxx.xxx.207.143 was it's broadcast address?

I'm at my wits end on trying to get this to work like this as I'm pretty sure that I have everything I need (IP's and Hardware) to get it to work, I'm just obviously not doing something right.

Thanks for any help you can offer, it will be greatly appreciated

From the sounds of it you have more ips that you can use but anyway.
depending your your distribution the files may differ
setup eth1 to be 130 like you said, then eth0 to be something like 192.168.0.1
Modify the /etc/sysconfig/network-scripts/ifcfg-eth1
and there's an option for broadcast address change that 255.255.255.240 like your isp gave you and make sure that after you save the file and restart networking that you can ping the internet from there.
since this is a static ip assignment you need to setup the /etc/resolv.conf file for dns lookups as well.
After you get that done make sure at this point that you can get to the internet from here. like try ping etc.
then setup ipcop to do whatever you want.

Now, we are given the IP range xxx.xxx.207.128-xxx.xxx.207.143by our ISP with the Subnet Mask of 255.255.255.240. The DG814, however, usually picks up a different IP address, this being xxx.xxx.147.222! Should it do this?

It's a routing function to have different numbers.. .
Just like sending packets for google via an interface numbered 192.168.1.1
The DG814 needs to know where to send incoming packets to, and where to send outgoing packets to as well.
The static routes function does that.. making the DG814 just a step in the delivery process..
What internal ip number did it give itself? and what default gateway/upstream router?

You need to set a configuration that treats IPCOP as the destination for incoming packets, maybe even with multiple ip numbers on IPCOP.
I doubt IPCOP has the settings available to do this however, that's advanced stuff..

The other option is to configure the DG814 as the destination of the incoming packets, which requires it to NAT outgoing packets..
