Chapter 8: VPN—Virtual Private Networking
88 WatchGuard Firebox SOHO 6.1
this feature to discourage users from creating Web servers. These
providers usually offer a static IP address option.
How do I troubleshoot the connection?
If you are able to ping the remote SOHO 6 and computers behind
it, your VPN tunnel is up and running. Any remaining problems
are probably caused by the MS Networking or the applications
being used.
Why is ping not working?
If you cannot ping the local network address of the remote
SOHO 6, follow these steps to classify the problem:
1 Ping the external address of the remote SOHO 6.
For example, at Site A, ping 68.130.44.15 (Site B). You should get a
reply. If not, verify the External network settings of Site B. If they are
correct, verify that computers at Site B have access to the internet. If you
are still having trouble, contact your ISP.
2 Once you are able to ping the external address of each SOHO 6,
try pinging a local address.
From Site A, ping 192.168.111.1. If the tunnel is up, you should get a
reply from the remote SOHO 6. If not, re-check the local settings page.
Make sure that the local DHCP address ranges do not overlap. That is, IP
addresses on either side of the tunnel
must not
be the same.
