No LAN Internet Access

When I stated it was working the other day, the hardware setup was (IPS Modem -> AP -> Client PC).

The AP is an old Linksys WRT54GL router with DD-WRT installed and setup as a wireless switch. By working I simply mean the Client PC could get to www.google.com. It was unable at all prior.

Testing again today. The Client PC is no longer able to get to www.google.com. pfSense can still ping www.google.com. I did nothing to the system over the weekend. Left it on untouched.

This morning I changed the network layout to be similar to how it will be when put into use (IPS Modem -> Gigbit Switch -> Client PC / AP / etc.).
Still not working, meaning Client PC unable to get to www.google.com.

And are you able to query with nslookup? Your post was timeout even talking to pfsense.

Did you look in the log, is unbound restarting over and over again?

kaysersosa

nslookup - DNS request timed out on the Client PC.

Attached are the last few DNS Resolver logs.

You have a problem there could not fetch dnskey.

I would suggest you up the logging level and then do a few queries for stuff. Quite possible your isp is messing with resolving..

Average 20 sec processing time??

look here

Your dns is not functioning… See my processing time and how many queries..

I would suggest you install dig and do a trace for something to see why your having problems...

That is a full resolve from my client.. lets take pfsense out of the picture for you resolving and do some tests with dig on your client. You can download it here, just install the tools in the bind install.

https://www.isc.org/downloads/

Your dns is not functioning correctly that is for sure.. You could try using forwarding mode vs resolving. But I would be interested in finding the root cause of your problem.

that is not a +trace..

You got back nothing from unbound.. You should of gotten back roots and walked down from there.

Force getting the roots… do say

dude change your client to use 8.8.8.8 as its dns… Then do you dig..

So that allowed you to get the roots, but after that client will use its default dns to get the IP address of roots. Your case that seems to be broken.

If you set your client to use 8.8.8.8 and then do a

dig www.google.com +trace

it should work

kaysersosa

I think I know where to make that change, see attachment.
Added the 8.8.8.8 and the 8.8.4.4 and unchecked DNS Server Override.

Run on Client PC after change above.

Forgot to mention that on the Dashboard page under DNS server(s) I see the following.

127.0.0.1
8.8.8.8
8.8.4.4

Prior it was showing
127.0.0.1
99…from ISP modem
99...from ISP modem
anything I added

johnpoz

all meaning less..

Can your client work when pointing directly at 8.8.8.8 and not to pfsense.

kaysersosa

Yes, hooked directly up to the ISP modem it can connect to the internet.

johnpoz

Dude point your client to 8.8.8.8 leave it behind pfsense..

This is not that hard to pin down..

kaysersosa

Sorry miss-understood what you were asking.

Network setup
ISP Modem -> Gig Switch -> Client PC / AP / etc

I hard-set 8.8.8.8 as the DNS on the Client under Network/Properties.

The client can now get to the internet.

kaysersosa

So I should be good if I can get rid of the 127.0.0.1 on the pfSense router?

Dashboard page under DNS server(s) I see the following.

127.0.0.1
8.8.8.8
8.8.4.4

Where is this setting at?

kaysersosa

Network setup
ISP Modem -> pfSense -> Gig Switch -> Client PC / AP / etc

Forgot to add the pfSense in earlier in the thread.

johnpoz

If client is working fine using 8.8.8.8 then you have 2 choices troubleshoot why pfsense resolving is haivng a problem.

Or just turn off resolving mode and use forwarder mode and point to 8.8.8.8

No you are never going to want to remove loopback, that is pfsense asking itself. If pfsense doesn't ask itself it will never be able to resolve any of your local host names. And your clients your going to want to point back to pfsense once pfsense is just forwarding..

But pfsense should be able to just resolve.. So I would be more curious to why it can not resolve?

kaysersosa

Just for your reference. The ISP modem has 2 ports on it. I have my pfSense router in one of the ports and my active DD-WRT router in the other. DD-WRT is running my home network currently.

Ok, so I removed the hard-set 8.8.8.8 as the DNS on the Client under Network/Properties. Then on pfSense under Services/DNS Resolver/General Settings - unchecked enable and saved/applied and thn on pfSense under Services/DNS Forwarder I checked enable and saved/applied. No internet on the Client PC.

Are there any other settings required with the DNS Forwarder? If not and you are willing to help I'm all for attempting to troubleshoot the DNS Resolver.

johnpoz

If your using forwarder then it should be forwarding… It should forward to your isp dns or what it gets via its wan.. Or what you put in the settings.

You sure its running.. Validate that pfsense can resolve using the dns lookup...
