Client Tests

• Test if the client can ping the LAN IP of the firewall
  • If this fails, check the LAN rules, client IP/subnet mask, LAN IP/subnet mask, etc.

• Test if the client can ping the WAN IP of the firewall
  • If this fails, check the client’s subnet mask and gateway

• Test if the client can ping the WAN Gateway IP of the firewall
  • If this fails, check the client’s subnet mask and gateway, and double check Outbound NAT on the firewall

• Test if the client can ping an Internet host by IP address (e.g. 8.8.8.8)
  • If this fails, check the client’s subnet mask and gateway, and triple check Outbound NAT on the firewall

• Test if the client can ping an Internet host by Host name (e.g. www.google.com)
  • If this fails, check the client’s DNS settings, and/or the DNS Forwarder on the firewall (Services > DNS Forwarder, Diagnostics > DNS Lookup)
