I was just wondering if anybody might have had the same problem, and if so what did they do....
I have 4 computers running various versions of windows, linux and BSD, and the other day I bought 3 old 486's with the intentions of using one to run IPCop, one to set up as a kind of syslog server and the other I will probably leave it as it is running win95...
Anyway, I downloaded IPCop, bought an old serial mouse, two network cards and went to buy a new modem. The problem is, I was just looking for an external ADSL modem (on it's own without a router) and it has to be ethernet (as I already have a usb one, and being an old computer it doesn't have any usb ports), and although there were plenty of ethernet modem/routers but none were just a modem...
I was thinking of giving in and buying a one port modem/router but the guy in the computer shop advised that, since IPCop is a kind of firewall/router it might not be a good idea trying to route already routed traffic, as it may cause problems...
So what I was wondering whether this was right, and has anybody else has managed to get away with using a hardware router with IPCop without any problems, or does anybody have any other solutions..
That's what I was thinking, but I asked somebody a few days ago (in another computer shop) whether I could add some add some usb ports, and he said something about 'not being able to get the cards anymore'....
If I knew a place to get hold of old defunct hardware I'd probably buy one.. Would a newer one work, as I've only been using computers for about 4 or 5 years and I wouldn't really know.
Have they changed that much in the last 8 years or so, as long as it's usb 1.1, I should imagine it would be alright...

there are a few dsl eth only modems comming out now, I personally run the DLink DSL 300G+ which acts as a standard dsl modem, I then control all routing via my bsd gateway which sits 1 hop on from the modem, and it works perfectly, I have also used this setup with IPCop 1.3 and again, it worked perfectly
I wouldnt recommend trying to create a 'double nat' setup like your thinking of as it will create nasty problems, you may get a connection but things will behave very strangly (or have done whenever I've tried it before) the only other option would be if your router/modem supports dns_spoofing

Thanks PhoeniXflame, I was beginning to think I wouldn't be able to get one...
I've managed to find a shop not far from where I live that sells that modem, it will take them 2 days to get it in stock but the way things were going I probably wouldn't have got one by then anyway...
Distribution: OpenBSD 4.6, OS X 10.6.2, CentOS 4 & 5

Rep:
"Not able to get cards any more"??? That's ridiculous. My brother just bought a PCI USB controller card a few weeks ago. I think the "computer shop guys" that you're talking to are full of crap.

if we are talking about an older system it might not have the capability to use pci cards, and I'm sure they do exsist but I've never seen an isa usb card ...
I went to that websote and looks interesting. Have you got any experience regarding their ZyXEL ZyWALL 2 firewall ?
I was thinking of using IPCop but just wondering
