Topic awaiting preservation: Linux Gateway (Page 1 of 1)

I have a computer Running Linux. I also have a router. I plugged my internet into my Linux computer, and I have another NIC card for the nnetwork cable to leave and into the WAN port on the router. How do I set up Linux Redhat to be the Gateway, and my router distributes the IP addresses to other computers??

Thanks

The way you are thinking about setting it up would make your redhat box the router instead. You will want to plug your second nic into an open port on the switch, not the WAN. You'll need to get a DHCP running as well as iptables. iptablaes is more than likely running already although you will need to make quite a few changes to get it to act as a router. Take a look at this thread at linuxnewbie.org : Click Here. There are tons of threads on this at LNO, keep searching over there if this link didn't help

Unless you are doing this as a learning experience, I recommend leaving the routing and firewall to your hardware router. I always try keep as much of my overhead on external devices as I can. On the other hand, knowing iptables can come in very handy down the road.

I think we need to ask...

why do you want your linux box as the gateway and not your router?

what is your end goal?

Ok, I'll situate Linux server behind Router. Then what port should I open up for hosting a WEB server and FTP server?

FTP is generally on TCP ports 20 and 21. HTTP is on TCP port 80 in most cases. Just make sure you have those TCP ports forwarding to the IP of your Linux box.

Another question, how do I enable Network sharing from a Linuuuux Computer to a Window computer? What program on linux must I use?

I use Samba to enable file sharing. http://www.samba.org/ I think RedHat 8.0 has Samba installed outa the box. It should just be a matter of tweaking the config and starting the services needed for it. I did have to open a few ports with iptables to get Samba to work. I can't remember which ports off the top of my head though. I'll see if I can't dig up the port numbers if you need them.

I have Redhat 8.0. Where is Samba located in GNOME menu??

wow.

Time for you to research.
I'd start with a bash prompt primer.
