What is NAT!? and how to use it?!
I've been hearing about NAT here and there lately and am wondering just what exactly is it and how do I get it (hopefully free) and how do I set it up?
Here's my set up. 4 boxes networked. 1-win2k box, 3winme boxes. Verizon DSL with modem attached to ethernet hub w/crossover cable (no router yet). Running zonealarm for at least some type of protection. Thinking of upgrading to zonealarm pro. I have an older version of winproxy that I was wondering if it could be run to add additional protection. This version of winproxy (ver.2) doesn't have NAT built in as does it's newer verion (3.0).
I have it set up this way because I don't want to have to leave a computer on for the other computers to connect to the internet. I like booting up whereever I am in the house and getting online. But I want some type of security too.
Planning on getting a router soon. Was buying one from someone else but that hasn't worked out yet for some reason. Until I get a router what's the safest set up?
Thanks in advance for any help I get.
I can't explain it, but here's a definition.Short for Network Address Translation, an Internet standard that enables a local-area network (LAN) to use one set of IP addresses for internal traffic and a second set of addresses for external traffic. A NAT box located where the LAN meets the Internet makes all necessary IP address translations.
NAT serves two main purposes:
Provides a type of firewall by hiding internal IP addresses
Enables a company to use more internal IP addresses. Since they're used internally only, there's no possibility of conflict with IP addresses used by other companies and organizations.
Allows a company to combine multiple ISDN connections into a single Internet connection.
If you get a cable/dsl router, it will do NAT for you.
Thanks for your help fellas. Going to check out this link now.
My DSL modem is has NAT. Not the most convenient feature, but oh well.
Pretty much what it does is keep an internal and external IP address. You usually have a dynamic IP with this setup.
Are there any free software programs out there that provide NAT capabilities? Trying to avoid spending more money... but will if I have too.
Not free with but not too expensive either ... http://www.nat32.com
Thanks to all and thanks DVNT1 for both links. That first one really helped a lot. going to check out the second a little more. I already downloaded the file there.
Your Welcome! Please post a follow up especially if you find a free or better solution.
If I find something I sure will.
