Intenet is not accessible using PFsense
-
Almost everything is default
I don't know what shall I do -
Well if you can't ping the gateway from pfSense then either the gateway is not responding or pfSense is not actually connected to it.
Does the gateway appear in the pfSense ARP table?

Concerning the gateway , it is working correctly because when I use the cisco router instead of PFSesne , the ping to gateway is ok.
but as you said , perhaps the pfsense is not connected to gateway, and that led me to a fact which is , there is a cisco switch between the pfsense and the gateway(ISP) and there are some configuration on it , so maybe the problem from there?
concerning the ARP table , I need to check that. -

Certainly could be. If it's not in the ARP table it's never going to work. And that is a layer 2 problem at least.

I discovered that ping between pfsense and gateway of isp is ok. (I was wrong before because I said ping is not ok bt pfsense and isp gateway)
Also ping from pfsense to 8.8.8.8 is ok
Ping from any lan to pfsense wan ip is OK
But ping from any lan to gateway isp is not successful. -
Ok, that implies there is no route back which probably means outbound NAT is not being applied.
Start a ping to the gateway from some internal client that fails. Then check the state table.
You should see two states created, on the internal interface and on the WAN interface. The on the WAN should show NAT as it leaves.

Reviewing the above screenshots you posted you have, for some unknown reason, obscured your internal private IP range, But it looks like the automatic outbound rules only cover the LAN subnet and local /30 transport subnets.
Switch to hybrid mode, add rules to cover other traffic. That could be one rule for all local 10. subnets.Steve

Okay , I will switch to hybrid mode and will give the result, but how I can add a rule to cover all the subnets , I think I have approximately 24 subnets, is it something like 0.0.0.0 0.0.0.0 next-hop-ip.
Note: I did not change anything in nat and I left it as default.
-
Moreover, how to check that pfsense is sending the back route to cisco switches , ospf is enabled on all devices including but how I can make pfsense redistribute routes via ospf, I remember I checked an option under the title redistribute in ospf setting and don't know if that was enough .
-
If they are all 10.x.x.x as shown in your diagram you can just use 10.0.0.0/8. That's probably a wider subnet than you need though. Better to specify the minimum subnet size to cover them.

Check OSPF status on the switches to see if pfSense is advertising a default route.
Or just try to connect out from a client and see if that traffic is passed in pfSense.

Sorry , I was busy these days
I will do it
Thank you Steve
