Setup firewall in Solaris 7 or Linux

By ufs00083 ·
I want to setup a firewall for our small company and we have 128 ip addresses from
206.200.58.128 to 206.220.58.254 for example.
and the gateway is 206.200.58.1

How can I setup and implement the most efficient firewall by using Solaris or Linux platform to protect our web server, mail server and other workstations? I am trying not to using
192.168.x.x or 10.x.x.x scope of ip address for internal ip.

Any ideas?

You can try checkpoint Firewall 2000, for Solaris 7 in 32bit mode only and Linux 6.1 with Kernel version 2.2.x

Basically what you can do it separate the network segment in between the web server and the rest of the network. Or you can set up a DMZ segment and place the web server on the DMZ segment. You can assign yourself into any IP address. Usually 206.* actually more for public network class. Set up 192.* or 10.* for private segment and 206 for DMZ segment. You get the IP address arrange from the ISP for you DMZ segment.

You can use any commerical firewall like checkpoint, raptor, guardian etc., and still you can use public IP address for your internal network.

If you are looking for freeware you can look at fwtk. http://www.fwtk.org, this is simple to setup.But reserved IP (192.168.x.x) address are always suggested when you are using firewalls. This is the most secure and commonway of designing firewalls.
