Hi, Ok i have a simple LAN. I have one machine connected to the INTERNET running Redhat 7.3(2.4.20) with iptables 1.2.7a (Firewall+Router) and 2 windows machines behind it(192.168.0.10 and 192.168.0.11)also with internet access. But the windows machines have there configuration set up soo that there DNS server is the ISP DNS servers 207.12.67.100 But i have the firewall machine set up as a DNS server. Sooo i want the windows machines to have the firewall machine as there DNS server. What would be an example rule set for iptables for this? Soo the DNS request go from the windows machines to the Firewall machine instead of directly going to the internet! Thanks __________________________________________________ Do you Yahoo!? Yahoo!
