To protect an isolated computer on your network that has the WatchGuard Agent and endpoint security product installed, you can provide the computer with access to a WatchGuard server through the use of a proxy. For more information, go to Designate a Computer as a WatchGuard Proxy (Windows Computers).

However, errors might occur when you use a WatchGuard Agent on a computer that accesses a proxy from an isolated environment. Errors are commonly related to DNS resolution or IP addressing.

Try these steps to resolve proxy errors:

• From the proxy computer, select Task Manager > Services and verify that the computer shows the WatchGuardEndpointProxy service as Running.
• From the remote (isolated) computer, verify that you can ping the host name of the proxy.
  To test a connection to a proxy, at a command prompt from the remote computer, type:
  ping <proxy_hostname>
• From the remote computer, enable the Telnet protocol. By default, the Telnet service uses port 3128.
  To test a connection to a proxy, at a command prompt from the remote computer, type:
  telnet <proxy_hostname> 3128

If you cannot connect to a proxy, contact Support. When you contact Support, make sure to use the PSInfo tool to provide diagnostic logs for both the proxy computer and the endpoint computer.
