OPNSense firewall - Basic configuration
I had problems when trying PING to the firewall....When I started the firewall, for a few moments the PING worked and then few seconds after it stops to respond. From inside the OpnSense I could PING my Desktop but from my Desktop can not PING the Firewall.. My default "Default allow LAN to any rule" was disable because I want to control all the traffic that cames from my LAN to my WAN. So, I had to create a specific rule to allow ICMP traffic: Action: Pass Interface: LAN Protocol: ICMP ICMP type: Echo Request Source: LAN net Destination: This Firewall description: Allow Ping After this ( and this is important ) I need to run "States reset" ( Firewall->Diagnostics->Stated Reset ) to finally get the correct response of the PING to my Desktop.
