Hello and thank you for quick responses.
The internal network is structured like this:
www -->pfsense–>switch–>8 computers.
pFsense box has a WAN of 192.168.1.1 and from it, LAN goes with 192.168.10.1/24 network. I can browse the Internet from all computers on the LAN, I can ping other computers, but I can’t browse the LAN for shared folders, nor access the CentOS server.
CentOS server has 192.168.10.99 IP and I can ping it from any computer from the LAN.
No VLANs, nothing fancy.
Here is the setup
