Puzzled - Internet access

[Markbhai]

Hi all.

I am having a very strange issue, which I can't get my head around so I am looking to see if anyone has seen something like this before.

I have no internet access from inside the network, I can't get to google from a browser or ping google from a workstation smd prompt (100% lost packets)
I can, however access the firewall remotely - by loging in through the web gui at my url - furthermore, when accessing the network I can see that all clients are registered with valid ip addresses etc.

Can anyone advise of any diagnostice I can run (remotely as I am 200 miles away) or if they have seen anything like this issue?

Thanks

Mark.

I can also ping google from the router diagnostics page…

from pfSense GUI, did you:

• check that WAN is up
• try diag tools and check pfSense can access internet
• look at logs in case packets are dropped or rejected

Diagnosis so far…

I can ping 8.8.8.8 from the default source with no packet loss

I can ping 8.8.8.8 from the WAN source with no packet loss

I can't ping 8.8.8.8 from the LAN source - 100% packet loss.

I believe this indicates an outbound firewall rule issue, which I have set up as:
NAT->Outbound
Automatic Outbound NAT rule generation

WAN  127.0.0.0/8 & 123.168.4.0/24  *    *    500    WAN address    *    Yes
WAN  127.0.0.0/8 & 192.168.4.0/24  *    *    *        WAN address    *    No
