I'm going to guess that by disabling DHCP on the Netgear router, you are letting the Origo handle those chores. If that is the case, then any computer getting an IP address from the wireless side will probably end up with a 10.0.0.x address. So from the LAN side of the Netgear, trying to access a 192.168.1.x address isn't going to be resolved. However, you might
be able to access it from the WAN side of the Netgear router. I'm not familiar with Netgear, but a lot of routers have the ability to access their config pages from the Internet. If your router can do this, you could turn it on and try accessing from the WAN side.
and for some reason gftp (or any ftp software) now hangs when trying to retrieve the list of files. I can ssh and scp with no problems but ftp doesn't want to play.
What is probably happening is the various ports used by FTP are getting hung up in all the exchanges. Have a read through this
to get a better idea of how FTP uses ports and how you might be able to lock them down to a specific range.
You know, it this case you might be better off letting the Netgear router handle the wireless DHCP, and setting it up with a static WAN IP address in the 10.0.0.x range and pointing the gateway at your Origo router.
