How to change WAN IP & Gateway in one step remotely

[stompro]

Hello, can someone tell me what the correct procedure is to change a static WAN IP address and gateway remotely in one step?

I keep running into the fact that you can only change the Gateway after the WAN IP address is changed, since the Gateway gui checks to make sure that the gateway is in the WAN network.

If I apply the IP change then I cannot reconnect since the gateway is wrong.

Thanks
Josh

Could you not simply edit the config.xml and replace these two values, then reboot the box?

Use the "add a new one" link on the WAN page under the IP address box. Make a new gateway (new name) and it will let you add it there.
