Virgin Hub 3 Modem Only not working

[tomwgf]

Hi
While with my Hub 2 Modem Only worked fine with my netgear router. For some reason the Hub 3 does not work.
the only way i coudl get it to work was by setting  it back to Router. Then it worked. Though now i  have 2 wireless networks running.... 

which leads me to Port forwarding  and Minecraft

use modem mode with a PC get that working then copy PC MAC to your  netgear router WAN interface

if i can understand this - i might give it a go. but at the moment it is workin (even if i means both are routers and a minecraft server is extra painful )
