Title: Output LAN to Internet DNS server
Post by: cibernautaX3 on January 20, 2012, 02:14:44 PM

Hello

I set up my DFL-260 to LAN (192.168.2.x) has an exit to internet through my DNS server (192.168.10.10). Users who can change the DNS settings on the other google either do not have internet.

So, what you want? Just deny users to use external DNS?

Hi,

If you want to do what Danilov asked, the way to do it is to create an ip rules to force the dns service to be use with your server and so on.

Choose what you need

* Make DNS relay

Rules > IP rules
SAT lan/lannet core/lan_ip dns-all, SAT: new destination = yourdnsserver
NAT lan/lannet core/lan_ip dns-all

* Pass DNS traffic only to specified DNS server
Make this rules before lan_to_wan rules

NAT lan/lannet wan/yourdnsserver dns-all
Drop lan/lannet wan/all-nets dns-all
