Looking for a inexpensive router that will allow me to disable NAT. Anyone have any ideas. I currently own a smc and linksys, both of witch I cannot disable NAT. Using Bellsouth DSL and have purchased 5 ip address, can?t really utilize them with nat enabled. Thanks for any info.
NAT Router?

None of the Routers can Disable NAT.
When comes to Entry Level Cable/DSL Routers, NAT, Routing, and Firewall, are in essence the same word.
No NAT no Router. No NAT, no Firewall.
By plugging the Modem Directly to a Regular Port (use a crossover CAT5), you basically bypass the Routing.
You need to disable the Router?s DHCP server as well. What ever you do with the Router do it first, once all your computers go on External IP you will not be able to connect to the Router Menu since all your IPs will be Public. In other words you probably do not need a Router but just a simple switch.
BTW. I hope that you have a Good reason to use 5 external IPs. Most people who have for free few IPs do not use more then one (I know it is hard to have something for free and no to use it).
Having a Network that consists of 5 external IP might be problematic for LAN usage

You could get a switch or hub and put that in front of the router . That would give your extra IPs to the comps on the switch and one to the router.
Thanks for the info. I guess i just need a hardware firewall.
Im using the 5 ips for work, SCADA related.
Yea that would work fine, i just need to add a firewall inbetween that. Thanks for the advice. Software firewall seems to make pcs run alittle slower.

Decent Software Firewall Slows down Internet? Nah, not in a practical term.
The few msec. that are saved in theory by avoiding adequate Security will translates into Hours of cleaning in matter of short time.
In a matter of fact for Home and SOHO users software Firewall is more important than Hardware Firewall.
Why?
Router?s NAT Firewall protects you only from casual Hacking, and DDOS attacks.
Hackers are mainly after big cooperate systems. Unless you are a teenager that is involved in "Server Fights" with your friends, hackers are not your main problem.
Cable/DSL Routers Do Not protects you from:
Progarms calling Home, Viruses, Spyware, Bad Attachments, Browser Hijackers, Winsock Thrashers, Worms, etc.
Link to: Basic Protection for Broadband Internet Installation.
Even if you take all the security precautions mentioned above, there is also the ?Junk? that comes embedded in the code of sites that you log to, and since you ask for it will get to your computer regardless of Firewalls.
Few days ago I cleaned a Client Computer form 132 Worms, and countless amounts of Spy Modules.
The computer is behind a Router that I installed + Software Firewall.
However, few weeks ago the client Disabled the Softwrae Firewall (He does not remember why).

the true downside of a software based firewall lies in the fact that it is blocking the packets on the pc you are trying to protect. a standalone firewall will block them long before they reach the LAN.

Flexibly is one of the capacities that make Humans different than many other life forms.
There is many way to slice the pie.
By trying to illuminate the different ways you give people a choice to use what ever they deem is appropriate to their situation, and within their Knowledge.
I thing that Linux people in there Zeal to spread the message tend to ?Reduce? so many posts to one sentence containing the word Linux. It starts to look like Linux is a Form of "Snake Oil".
It would much better if some of the "Zeal" will be put into Web Sites that help ?Simple? people (as oppose to Macho Techs) to understand and implement Linux.
Right Now for Newbie?s and average users it easy to learn and speak Klingon.

If you do want to go with a Linux Box you might try this.
Link to: SmoothWall Express 2.

Yes. thats why its nice to be informed about all the different choices.
No one here is trying to spread a "message" about linux. I am only offering another solution that will do what he wants. As far as the one sentence posts, why spend a paragraph explaining something if the original poster has no desire to learn these new methods? Why not just pose a possible solution, then worry about the details if he decides to explore that route?
It sure would be, any volunteers?
Besides, we all have to start somewhere. When I first started messing around with linux, I had no idea of what I was doing or how to accomplish certain tasks. But I set myself a goal and I tinkered until I met it, then moved the rung on the ladder up one notch. Also, its much more fun to learn something when you have an actual use for it, rather than learning just for the sake of learning.
Cisco PIX 501, is one of the cheapest I know of that will do this... or it will allow NAT/PAT with multiple outside IP's for added security/addressing.... and its a GOOD firewall, unfortunately its going to be at least $400
Looks like the Zyxel ZyWall 10 will do multinat which will work too, and that sucker is about $280.... dunno about the quality of this product though, I can personally vouch for the pix however ;-)

pc101, I have a Belkin F5D5230T4 and it has an option to enable/disable NAT. Micro Center has these currently on sale (closeout, really) for $9.99:

The Linksys BEFVP41 and WRT54G I believe both also have such an option. There are very interesting firmware hacks available for the WRT54G that might be especially worth your while.
