Access host on the LAN using public IP

[michaeldemb]

@johnpoz Lets assume I can use DNS. Why DNS Forwarder Host Overrides is not working?

[johnpoz]

Again... Are you using the forwarder? There are two DNS software packages (3 if you install bind optional package) on pfsense.. There is the forwarder (dnsmasq), and the resolver (unbound)... Out of the box pfsense uses unbound.

You have to place your override in the system your using.. Its that simple

[michaeldemb]

@johnpoz I am using Forwarder (dnsmasq).
All is configured, but the PF still responding with the value from public DNS rather than from the overwrite entry. See screenshot:

@johnpoz yeah i need to be more verbose next time, i was in a hurry because a customer entered my store in that moment what i meant is you need one of the options on that link, nat reflection or split dns but it's well documented that split dns is the best course of action

[johnpoz]

Well your not asking pfsense - so why would you think it would reply with your override?

Your override is not on freaking googles dns servers for gosh sake!

dig @ pfsense-ip !!

and your pc need to use pfsense as dns server and only that

[michaeldemb]

@johnpoz Man, you need to better pay attention to questions. I am asking PF, but for some reason, it is forwarding the request to upstream DNS, instead of returning the value from overwrite table.

You are NOT asking pfsense - its right there in front of you!!

You clearly have set pfsense to ask google - it doesn't do that out of box... Set pfsense to ask itself, which is the default! And then test your override asking it..

[michaeldemb]

@johnpoz PF is set as my default DNS. It is configured with DNS forwarder that goes to google. So yes I am asking PF, but it just forwarding to google.

NO your NOT.. Your queries were direct to 8.8.8.8 - its right there in your screenshots!!

[kiokoman]

if it's not like the screenshot of johnpoz check this options

[Bob.Dig]

@michaeldemb Best you start with a fresh pfSense...

[michaeldemb]

@kiokoman Thnks this is it. Also Override is working now. PF simply had cached DNS and was returning the old values. All is working now.

[johnpoz]

No it had not cached dns.. Once you set an override any "cached" records would of been overwritten since the act of creating a host override restarts the dns service.. You were not pointing to pfsense for dns..
