Can the WAN IP address be changed remotely on a SonicWall TZ 210, like a Cisco IOS?

Hello,

     We have been able to change a WAN IP address on a Cisco router (IOS) remotely, before, when the internet service provide changed it. This was done by writing a new WAN IP configuration to the flash and reloading it. Can something similar be done to change the IP address remotely on a TZ 210 SonicWall router? Is there any way to change the WAN IP address on that model of SonicWall router, remotely, without having to connect to the router directly?

To access a sonicwall, you either connect to the web interface via the LAN or WAN (or whatever interface is configured) or via telnet to the serial interface. You can't modify the settings of a file offline and upload them to the sonicwall. You could modify a spare sonicwall and save the settings then import them into the production sonicwall, but this would still require the connectivity I mentioned above.

I suppose the short answer to your question is, no.

@Digitap, you are correct you cannot change the WAN remotely as the configuration is live and changes take effect immediately so you could not write and reload like a Cisco where it will re-negotiate with the upstream device :)

Sorry for the delay on this. The issue in question dragged on for a while.

So, it's not possible to use SSH management to do this either?

What version are you running? I am running 5.8.1.2 on my TZ 200 and NSA 240 and apparently I can do this now. I logged into the management interface, changed the X1 IP from 192.168.10.3 for my lab to 192.168.10.4 and as soon as I did that the browser cached the changes and automatically redirected me to the new public X1 IP. As long as both are live you should be able to do it remotely. One thing of note it did prompt me to re-generate the management SSL certificate for the new IP since it is self signed. Hope this helps.

Certificate Prompt
