My TZ370 is connected to our ISP via DHCP

Karl

I want to use the TZ370s VPN capability using Netextender to access the firewall. Our TZ370 X1/WAN interface is configured DHCP. I couldn't find any info on how to configure and access our firewall, since it's on DHCP, and the IP could change at any time. Thanks for any help in advance.

Hi @KARL,

Thank you for visiting SonicWall Community.

Please use below KB article link as a reference to configure the WAN interface on SonicWall as DHCP. You will have to enable the HTTPS slider under MANAGEMENT to manage the SonicWall using WAN IP.

Since the WAN IP address is going to be DHCP and it changes randomly, it would be best to configure the DYNDNS on the SonicWall so that a domain name is used to manage the firewall even with the IP address change on the WAN side.

Hope this helps.

hi @Karl

For resolving the WAN Dynamic IP issue while using the VPN client / Netextender, use DynDns service.

Hi Karl,

Did you ever get this working? I setup DDNS etc but don't know how to progress.
