Virgin Hub with T40 Watchguard firewall

[Tony1952]

I'm new to Virgin media.

I am trying to configure a Virgin Hub and a T40 Watchguard Firewall.

I need the hub in pass through mode. This seems to be a hard thing to achieve. Various sources say the wifi is disabled in pass through mode. This never happens. I have turned off the DHCP, I have turned off the UPNP (there is no RG mode as this is a bussiness hub). The access to the Hub has changed to the address 192.168.100.1 The wifi still works.

In the firewall I have set my fixed IP address (as supplied by Virgin) with subnet /24. I have set the DNS to a pair recommended for use with Virgin. I can't find a gateway address but have tried 192.168.100.1 and several others. 

The firewall reports the interface as UP. I can ping the fixed IP address from elsewhere and when I turn off the firewall I can't. But it doesn't work. I can't even ping 8.8.8.8  (So this is not a DNS issue)

Any clues please.

VM useless business hub and the way they give you your IP

As you have a subnet the hub has no modem mode or RG mode you must use the hub as is you can not route your full subnet by your router.

so the hub has your wan subnet /24? really? VM gave you that big of a subnet? 

Lets say your subnet is 92.234.0.1-92.234.0.254 you can't put on your LAN 92.234.0.1/24 so you have your WAN set to 92.234.0.1/30 then you can do small LAN subnets routing out your WAN with SNAT none like the biggest 92.234.0.229/25 then 92.234.0.65/26 then 92.234.0.33/27 then 92.234.0.17/28 and 92.234.0.9/29 then 92.234.0.5/30
