      hi
      I have a behavior that I do not explain:

      Context: personal environment, I have network knowledge

      Need: I am trying to use the nmap tool from site A to a machine at site B via an openvpn tunnel without success. It works internally on site B.

      Plan :
      LAN_A ---- [PFSENSE_A] === TUN OPENVPN === [PFSENSE_B] --- LAN_B

      WAN (modem / router / box): a public ip by pfsense.

      NAT rules: automatic outbound

      Firewall rules: for the purposes of the test: any / any

      Added packages: frr / openvpn-client-export

      Other functions assigned to pfSense: routes are propagated through the vpn in BGP (frr)

      Question: nmap does not see the machines up through the vpn, the result is positive locally.

      Imagined avenues: bad VPN or firewall conf?

      Logs and tests: the firewall rules are any / any and the vpn conf works for everything else (ping, ssh, nas)
