Transparent ip forwarding
 

I have 5 PC's at home and 5 public IP's asignend by my ISP. I want to set up a Debian router/firewall to protect and control my network, limit access to the internet for my kids if necessary, but without masquerading the IP's. For example I work with other networks that have to see my IP for me to access them.
Or let's rephrase, I want to build a Debian server for a network with public IP's inside.
I know my way around linux, but I have yet much to learn about networking.

Thanks a lot.

i *think* this should be exactly what you're looking for... http://freshmeat.net/articles/view/1433/

wow, 5 public ip addresses, are you paying extra to have those?? i'd love to have 5 public ip address, i could host all sorts of servers :)

I only need one...
 

I'm doing a lot of research and documentation, but I still haven't figured out how to make my debian stable, with 2.6 kernel work as a router/firewall server :study: .
I want it to route my ip's so the other can see them, the only thing my server shoul do is to restrict access when I want to and provide my mininetwork with the decent security linux provides.
By this time i am stuffed with articles telling me how to make a router with 1 public IP and the internal network with privete IP's (e.g. 192.168.x.x).

I also want to do this without a proxy server, I know this is possible, also DHCP server so in case I add another PC I shouldn't waste time setting up the network again...

I hope that by the time of my retirement I shall figure it out :) .

Or maybe someone here can point me in the right direction or even better, help me with a specific step-by-step routine that aplies to my case.

So back to basic linux networking I go, I am not sorry for that, I learned a lot, hte support of linux community is the greatest of all, but I still haven't achieved my goal.

As far as the parental control aspect goes, a proxy server might be exaclty what you're looking for. But you can also do that on a client by client basis with Parental Control software.

You can also, most likely, use any of the "router/firewall" configurations you've already looked at, and just ignore the NAT and PAT implimentations. This would allow your public ip's to be used through-out.

This is a pretty neet webpage on home linux servers, but its based on fedora. Aside from that, it might be of some help to you.

This page is on setting up the linux box as a firewall, which you should have no problem also making it route.

Too difficult to me.. , but here you'll find the right answer.

Definitely is a matter of "s"natting.
Hope this helps
