Cable Forum - View Single Post - VM Business Installing a firewall behind the Hitron box

Hi All,

Apologies for the long winded introduction...

I have a VMB account with one static IP address. I would like the Hitron to act as a modem and use a IPFire [1] as router.
Currently I have this setup with my DSL connection (openreach modem). I discovered that I cannot change the HITRON mode to modem and was told that this is because I need to upgrade to multi-IP in order to do so.
However, looking at this thread [2] I noticed that the recommendation is not to activate the modem mode.

So I wonder if I really need to upgrade to multi-IP or if instead it is possible to configure my network so that the Hitron just acts as a modem and the have the routing/firewall/DHCP/PortForwarding/VPN/... performed by my raspberry PI running IPFire

Note (in case it is useful): IPFire installation allows to select "static" as IP address setting for the interface to the internet (see image below) and requires to specify:

IP address: is this my static IP address?

Network Mask: is this /32 since I only have 1 IP address?

Gateway: should I ask VMB?

Thanks in advance!
