Using R6220 on Virginmedia Superhub 2AC in modem mode

Thanks Antinode

Sorry about confusion. The Superhub 2AC is actually a Netgear product. The Virginmedia label says it's a VMDG490 and I believe it's a rebadged modified Netgear C6250 but with 4 x Gb LAN ports. I kept the LAN default subnet at 192.168.0.1 but set the DHCP scope to be 192.168.0.100 to 254. So yes, you were correct that my 14 wired devices use reserved IP's in the range 192.168.0.2.to.99. I want to make the DHCP settings on the R6220 the same so I do not have to reconfigure the wired devices at all including all the port settings etc. Hopefully this would mean just setting up all the ports/forwarding and rules within the R6220 to match those that were in the Virgin hub. In effect then I could set the hub to modem mode and connect to the R6220 and if needed, remove R6220 and switch hub back to router mode. You may have answered my question about conflict with WAN side! I mis-read the link IP as 192.168.0.100 where it is in fact 192.168.100.0 as you mentioned was typical for DOCSIS cable modems. So I think I'll give it a try unless you can see any issue I might run into. Thanks for your help.
