I have been using a combination of the older Virgin Superhub and a Draytek Vigor 2900 but recently found I could not get the upgraded speed of 50Mb/s.
Virgin sent me a new Superhub 2AC but in the meantime I discovered that the (10 year old) Draytek 2900 just can't cope with more than 20Mb/s so I have changed it for a much faster 2920n.
The problem I have is getting the new Shub to output an IP address to the Draytek that is NOT in the internal IP range that I am using (192.168.0.x).
On the old Shub I was able to set its LAN-facing IP to 192.168.2.2 which the Firewall saw as a "WAN IP" and that worked fine. The new one won't accept that: "LAN ip address and cable modem IP address cannot be on same subnet". Of course it can't.
Virgin suggested trying a higher subnet number of 192.168.5.1 as the lower ones were reserved but it won't accept that either!
I'm baffled as to how to get this to work, but surely this must a common setup to have your own Firewall and not rely on the Shub to be the only layer of protection.
(BTW I am testing it unconnected to the cable network at present as I need to keep my current internet connection live until I can be sure this will work).
Any advice appreciated.
TIA.
Andrew
