LAN Interface

Troubleshooting Network ConnectivityTroubleshooting
  • Check that the LAN IP address is correct (Interfaces > LAN)
    • Using an invalid IP address (e.g. .0 or .255 in a /24) will cause problems reaching addresses locally and will not work properly.
  • Check that the LAN subnet mask is correct (Interfaces > LAN)
    • Using an incorrect subnet mask, such as /32, will prevent other hosts in LAN from finding the LAN to use as a gateway and vice versa
  • Check that LAN does NOT have a gateway set (Interfaces > LAN)
    • This will interfere with automatic outbound NAT
  • Check that LAN does NOT have “Block Private Networks” set (Interfaces > LAN)
    • Should be obvious
  • Check that LAN does NOT have “Block Bogon Networks” set (Interfaces > LAN)
    • See above
