No connection on red

Getting Started with IPFire

How does the ‘upstream DNS server’ ( in your LAN? ) intercept dns traffic?

To come back to the topic.
@barny , can you communicate from IPFire with the outside world?
This is essential, before we discuss any other issues.

For the moment my gateway is pfSense running adam:ONE. I had to switch to this a few weeks ago for business reasons, so to continue playing with IPF, I had to put it on my LAN, connecting IPF red to to my LAN.

adam:ONE is a DNS filter and it hijacks all outbound DNS requests to stop people trying to bypass it. It has firewall rules to DNAT any DNS traffic to itself … but you’ve just given me an idea.

So, I got it. The main problem was, I have to activate ip forwarding in sysctl, otherwise it don’t works. And in ipfire there was no DNS server configured, after I does that reolving was OK.

thanks for your help.
