Outbound port forward

[Arquivos]

Hi all.

I have a pfSense 2.0 box with 1 LAN and two WAN´s; Actually i´m facing a
problem:
i need to forward all the requests going out by the port 53 (DNS) to a
single external DNS server, in dispite off the DNS configured in the
clients. Can someone help me in that?

What you want is a NAT Port Forward entry on your LAN interface to
destination port 53 and a redirect target IP of the server you want to
force. I haven't tried this but I believe it will do what you are
asking.

This should work, i've been doing this a while back where I had a combination of a port forward on the LAN and a outbound NAT rule on the LAN interface to mangle traffic.

That was 1.2.3 or a early 2.0 beta.

Seth

I´ve tried this config and it didn´t work :(
In NAT por forward only internal IP´s can be specified and i need an
external DNS server, so i´m still in the dark.
Tks..

What if you enabled DNS Forwarder and forwarded All DNS Request to PFsense.

This works, and works great. Combined with open dns, it's a great way of
filtering domains.
