How Do I Troubleshoot The Connection; Why Is Ping Not Working - Watchguard Firebox X20E User Manual

How do I troubleshoot the connection?

If you can send a ping to the trusted interface of the remote Firebox® X Edge and the computers on the
remote network, the VPN tunnel is up. The configuration of the network software or the software appli-
cations are possible causes of other problems.

Why is ping not working?

If you cannot send a ping to the local interface IP address of the remote Firebox X Edge, use these
steps:
Ping the external address of the remote Firebox X Edge.
1
For example, at Site A, ping the IP address of Site B. If the ping packet does not come back, make
sure the external network settings of Site B are correct. (Site B must be configured to respond to
ping requests on that interface.) If the settings are correct, make sure that the computers at Site B
have Internet access. If the computers at site B do not have Internet access, speak to your ISP or
network administrator.
If you can ping the external address of each Firebox X Edge, try to ping a local address in the
2
remote network.
From a computer at Site A, ping the internal interface IP address of the remote Firebox X Edge. If
the VPN tunnel is up, the remote Edge sends the ping back. If the ping does not come back, make
sure the local configuration is correct. Make sure that the local DHCP address ranges for the two
networks connected by the VPN tunnel do not use any of the same IP addresses. The two
networks connected by the tunnel must not use the same IP addresses.
How do I set up more than the number of allowable VPNs on my Edge?
The number of VPN tunnels that you can create on your Firebox X Edge e-Series is set by the Edge
model you have. You can purchase a model upgrade for your Edge to make more VPN tunnels. You can
purchase a Firebox X Edge Model Upgrade from a reseller or from the WatchGuard® web site:
