Troubleshooting 3801HGV Gateway
What to Do
Navigate to Settings > Firewall > Advanced
Configuration. Select the HTTP checkbox from the
Outbound Protocol Control section to enable the HTTP
traffic to pass through the firewall.
Check if the VPN service supports PPPoE, L2TP, PPTP,
and IPSec ports. If not, then you must open the
supported port. To open the supported port, perform port
forwarding, that is, add a new user-defined application.
What to Do
Ensure that you populate the correct destination IP in
the Host Address text box.
Enable Syslog and enter the appropriate server location
to populate the logs at the remote node.
Ensure that you install a third party software to populate
the syslogs on the remote node.
