Question about NAT

[Splash]

You need a router that supports Multi-NAT. You need to be aware of the risks of leaving machines completely open to the internet though - NAT provides a pretty decent layer of support, and any ports open on machines that aren't properly secured are potential attack vectors. Remember that only one machine needs to be compromised on your LAN and then all of your other machines are suddenly a lot more vulnerable.

I am well aware of this. Do you know any specific routers or router/modems that can do this? It would be a lot easier to start making decisions of what to buy if you guys could recommend something.

Does anyone know of m0n0walls capabilities in this kind of situations? What about ZyWall 2 plus? Any regular SOHO broadband router which could do this? Ideas Ideas more Ideas please

I used to run a Draytek 2800 for this kind of thing, running a
2820N now which can also do it, but I simplified and am now back on a single ip address as I couldn't justify the expense.

M0n0wall, Smoothwall pfSense and the like all support this kind of thing as well. No idea about the Zyxel products.

Ok it seems I've run into a problem once again. Does anyone know if Multi-NAT works with ISP DHCP since our ISP doesn't hand out static IPs... everything must be obtained via DHCP.

Multi-NAT is when you use NAT with multiple public IP's. Since you can't get these you're out of luck.

Find another ISP who will give you a block of IP's and use multi-NAT or no-NAT.

Sorry to disapoint you but It can be done and it will be done I have already solved my puzzle and I'm in the process of building it. I need to learn a fair amount of stuff but I have already managed to pull 4 different public IPs from my ISP to a single NIC via dhcp and they all responded to ping like they should.

I might even post the details here when I'm done
