sonicwall netextender the server is not reachable

This makes me think the problem lies with the modem's configuration. Nothing has changed on the configuration side of the Sonicwall or the Windows server (DHCP and DNS), and I noticed the problem a few days after the new modem was put in.

The sonicwall VPN is configured to issue an address between 192.168.1.70 & 192.168.1.80 to clients. Local devices are given address on this 192.168.1.100+ pool. The sonicwall has no DHCP or DNS services enabled, it just sends its traffic to our Windows server that runs DHCP and DNS on 192.168.1.XXX. DHCP is enabled on the modem, and that issues a local address of 10.1.10.9 to the Sonicwall. The modem connects only to the Sonicwall. More details on the network setup that may be useful: No ports are being blocked at the modem level as far as i can tell, but that traffic just isn't getting through. No settings have been changed on the firewall, but under the new modem, people can no longer connect. The dell sonicwall SSL-VPN is configured to run on port 4433 (the default). Here's how the NetExtender app was previously used to connect:īut now when people hit connect, it pops up that error message from above, so the Server address must not actually be handing off? The server may be down or your internet settings may be down. If this does not fix your issue please reach out to our support team for additional assistance and let them know you used NetExtender 8.6.265 and the issue persists. The client PCs can no longer connect over the VPN- the NetExtender app pops up with the message: Error: The server is not reachable. Open a command line and try ping any device in LAN from a PC connected via NetExtender - you should receive a response. We have a static IP business connection from Comcast, and a few weeks back the box crapped out. This provides general troubleshooting instructions and discusses the troubleshooting tools available in the Appliance Management Console (AMC). So we have a Dell Sonicwall unit that serves as our firewall and also runs the VPN functionality via the Sonicwall SSL-VPN and the accompanying client side application, Sonicwall NetExtender.
