Do a packet capture on your WAN using the diagnostic menu and then repeat the ping attempt from a LAN client.

These are just a few lines taken out from the middle of the report, i hope is going to get posted and not flagged as a spam....

yeah that pfsense pinging its gateway.

Now do that sniff when you try and ping from the lan address to 8.8.8.8

Tom8888

@johnpoz
No i did not set a default gateway on the LAN, as the guide suggested not to do it as well

Doing the same test on LAN i just get a blank page (????)

Tom8888

Here is how my different machines are connected to each other:

i have a main router from where the internet connection is coming from, with 4 LAN ports AND wifi
a laptop is connected by wifi to this main router and i can control PFSense from this browser
a LAN wire connect the main router to an old pc, which is hosting a local site not on the web
a second LAN wire goes to a brand new (powerful) mini pc which has only the last version of PFSense installed
from the PFSense machine, there is a second LAN wire which goes to an access point, broadcasting a second wifi connection not protected by password

If i try to connect with my laptop to the other wifi coming from the AP of PFSense, i can still control PFSense from it, but NOT browse the web.
When i enter this command (pfctl -e) into the PFSense Shell (option 8), i can no longer access the control panel of PFSense, but if i insert another command (pfctl -d), then i can again visualize the interface.
In both cases i cannot browse the web, unless i connect directly to the main router.
If i eliminate the PFSense box and connect the wire from the AP directly to the main router, then even this wifi connection works perfectly.

@Tom8888

For that setup you need a WAN rule from 192.168.1.0/24 to "WAN Address" in order to come in from the WAN side the way you are doing it.

Tom8888

The problem has been solved, i will post the details but not now as here is 1am, thanks all for your support.

Tom8888

So, basically, i hired someone on Fiverr.com which after a month of struggles, has been able to do half the job i hired him for, the resolution of this problem i posted here will likely lead us to the final step, which is redirecting all the clients accessing the free wifi to a locally hosted site.
The problem was apparently a misconfiguration of the AP, so people could connect to the wifi, get an IP address but unable to navigate anywhere, as only a white page would display and say the connection was taking too long.

johnpoz

So your AP was either running a captive portal, or it wasn't actually in AP mode and was trying to route, etc. which was prob the same network on both sides, etc. Its wan and its lan.. So yeah not going anywhere.
