Updated below
So I have a fairly simple setup. A single gateway using a Cox modem. The way it has been setup for several years now is a fixed WAN IP address and then right below was a spot to add an upstream gateway. Now in the new setup is a drop down box with auto-detect and no other option. The advanced info says you must select one, but there seems to be no way to do that. I can go to System/Gateways/Configuration and add it there to no avail.
I thought the box was corrupt after the update, since I no longer could get out. I rebuilt from scratch and the same thing happened. The only way around it, is to select WAN to DHCP and it works. Is this a bug or is there another way to handle this?
So I finally figured it out. I was very close. The new version, removes the ability to add the upstream gateway right in the interface section. Now you MUST go to System/Gateways/Configuration and add the upstream gateway there first and save. Once you do that, then you can go back to the interface and select something other than auto detect. (I apparently did something wrong the first 3 tries.) :o
So the update really should take this into account, grab this data an populate the gateway configuration so it does not break things. Just my thoughts. Keep up the good work.
