Setup DNS Server on PIX Firewall Inside Interface
Posted on 2004-08-11
Hi, I am a beginner here and my english is not very good. I hope someone can help me.
I have setup 2 DNS server running Win2K3 behind a PIX-501 firewall, for my company.
Internal domain: mycompany.com
1st DNS Server name: ns1.mycompany.com
1st DNS Server Internal IP: 192.168.0.254
2nd DNS Server name: ns2.mycompany.com
2nd DNS Server Internal IP: 192.168.0.253
PIX-501 inside IP address: 192.168.0.1
PIX-501 outside IP address: 126.96.36.199
I have 2 available public IP addresses that I want to use as external IP address for the 1st and 2nd DNS server respectively. (188.8.131.52 and 184.108.40.206)
I have registered the domain name: mycompany.com and for the name server information, I put it like this:
Primary Name Server name: ns1.mycompany.com
Primary Name Server IP: 220.127.116.11
Secondary Name Server name: ns2.mycompany.com
Secondary Name Server IP: 18.104.22.168
My questions are:
(1) Can I query my name servers from the internet?
(2) How am I going to setup my Firewall so that it can change the external IP addresses of the name servers to their internal IP and vice-versa?
