Suspected NAT or VPN issues
If you use network address translation (NAT) in your environment, you must make some configuration changes in Observer. Using the TCP/IP port information in , you should be able to set up the NAT properly.
If the probe is outside the network where Observer is running, you must forward port 25901 from the probe’s address to the system running Observer.
When redirecting the probe, you must specify the NAT outside IP address instead of the address that Observer puts in automatically. By default, Observer tries to use its local IP address, which the probe will not be able to find. Select “Redirect to a specified IP address” in the Redirecting Probe or Probe Instance dialog and type the VPN client’s IP address.
