Linux Virtual Server

[Noeluylee]

Hi Guys,

I am new to linux and I am using Debian 3.0 R3. I have 1 ip address and I want to host a mail, web and ftp. coz In linksys router I can specify it on virtual server, ex.

private ip (of server) 10.10.10.3 port 21
privtae ip (of server) 10.10.10.4 port 80
private ip (of server) 10 10 10.5 port 25
and so on and so fort.

but I want to build a linux server and I want to get rid of the linksys router. in other words I want to have all my server running on linux including the firewall and proxy.

Thanks for you help in advance.

Regards,
Noel
