No internet access

So you can access the pfSense webgui using it's WAN IP from the Win7 VM but can't ping it?

Is the pfSense WAN getting an IP using DHCP?

Are the subnets different between WAN and LAN?

Here are some screenshots, I can't access the internet from my browser! Thank you for your comeback !

@stephenw10 I solved the WAN interface ping! Thank you Steve .
at the top there are screenshots regarding the internet connectivity problem . Thanks for your comeback

Ok, so you have a DNS problem. By default pfSense will hand the LAN IP to clients to use for DNS. Is Unbound running? Check: Status > Services

[ralf.lionel]

Yes, unbound is running

[stephenw10]

Then either it's unable to resolve or the client is not using it.

Check Diag > DNS Lookup. Make sure all configured DNS servers respond to queries.

[ralf.lionel]

Here is the result !

Ralf

[stephenw10]

Ok, Unbound isn't responding there. It should be on localhost.

Try resaving it in Services > DNS Resolver and test again.

[ralf.lionel]

is it correct ?

[johnpoz]

@ralf-lionel no that is not correct.

Your saying for the "domain" www.google.com go ask 172.217.170.100, so if you wanted to look up say host.www.domain.com go ask that IP..

[ralf.lionel]

@johnpoz then I have to put my WAN address? Thank you for your comeback.

[johnpoz]

@ralf-lionel NO you don't have to put anything in domain overrides.

Out of the box unbound resolves, and listens for queries on your pfsense Ips, one being loopback.

So when your clients ask say your lan IP 192.168.1.1, it goes and resolves what your asking for.

Pfsense just ask unbound on 127.0.0.1, the own internal address..

When you show 127.0.0.1 is not answering - points to unbound not even running.. Or it having a problem resolving, or forwarding if you had set that up..

[stephenw10]

Yes, sorry, I meant just resave the Unbound settings without changing anything.

You shouldn't have any overrides set there.

Here's what I'm trying to do with pfsense and OpenVPN. I created two Win7 VMs with different internal networks and 2 others for the 2 pfsenses. So we have:

Pfsense server: adapter 1 -> bridge access
adapt 2->internal network (server)
connected to Win7_ 1: internal network (server)

and the second

pfsense client:
adapt 1 -> bridge access.
adapt 2->internal network (client)
connected to Win7_ 2: internal network (client)... All under virtualbox.

I followed this tutorial https://youtu.be/-8xt7LUtYH4 and
I had finished the configurations on each machine and tried to ping Win7_1 in Win7_2 but it failed and I thought it was due to the internet connection where I could not access from my browser. What do you think ? (I am still an apprentice in the field of the network). Thanks again for your feedback.

@ralf-lionel said in No internet access:

https://youtu.be/-8xt7LUtYH4

That's a good tutorial. It will work if the sites/VMs are working correctly first. Which they are not, yet.

I assume you are using a different Internal Network for each pfSense VM in VBox?

The two Win7 clients should be able to reach the internet.

DNS is failing for the client you are testing and it looks to be because Unbound is not responding to queries. One thing that could cause that is if you have added a default route to the firewall via the OpenVPN tunnel so all Unbound's queries are being sent that way.
However that seems unlikely since the client behind it is able to ping external sites by IP directly.
I would still recommend disabling any OpenVPN setup you have added until both sites are behaving as expected. Then add it one step at a time.

Thank you all, it's solved !
