The best way to get around this is to put the hub in modem mode, then power off the hub, unscrew the coax cable, then power the hub back on and wait a few mins (with the coax still removed). After about 2mins, screw the coax back in (With the hub still switched on) and give it another 2 or 3 mins. You should connect and get allocated an external IP. If it hasn't connected after 5mins, reboot once more.

There's a fair bit of ceremony to get that to work, but it's the only sure-fire way I know of to change devices when in modem mode.



You should be able to just disable DHCP on the Asus and stick it in the DMZ, more or less the same result as modem mode, just the superhub is allocating IP addresses (which means you can't assign DNS, IP's, etc. or anything easily). The VPN should work the same.

Note that your external IP address will be different when in router mode and whenever you plug a different device in when in modem mode.

I put the ASUS in DMZ using the IP allocated by the SHUB having disabled DHCP. I am assuming that I connect the ASUS using one of its LAN ports. It appears connected to the SHUB and is still dishing out WiFi. Unfortunately I cannot access the ASUS user interface, whether I connect through ASUS WAN or LAN.
