Hi all,
I created a new vlan using my LAN as the parent interface and the computer in that vlan subnet can access the internet and ping the OPNsense gateway with no issue. The computer IP can be seen in the ARP and state tables as well as in the DHCP lease table. Could anyone please help me understand why in the firewall interface diagnostics, the firewall is not able to ping that computer? When I move the same computer to my normal LAN interface I have no problem pigging it so that suggest it not the windows firewall blocking it but I cannot figure out why OPNsense cannot pint it.
Could anyone please assist me in understanding the reason why?
Thank you all in advance
hi
have you got any rules defined to allow icmp on your lan/vlan in the directions required?
Note, you are ping-ing FROM the firewall TO your machine. Your firewall rule is the inverse.
Also, you did not select "Source Address" in the interface. Please try again with the correct interface.
