Configuring modem + separate router with two static IP addresses

[at0mic]

I've got two static public IP addresses

I assigned the first static IP to a Netgear DG834G and disabled NAT and DHCP.

I assigned the second static IP to a Netgear FVS318v3.

I couldn't get the FVS318v3 to access the internet but then I realised that the LAN side of the DG834G still had a local IP address even though NAT was disabled. I don't have a third static IP address so I also set this to the first static IP.

Now the DG834G has the internet IP and the LAN IP both configured using the first public IP which I would guess is an IP conflict but it works. Now the Netgear FVS318v3 can access the internet.

However, although the first static IP can be accessed from the internet, the second static IP cant (FVS318v3). How can I get the FVS318v3 to access the internet?

Do I need to buy a different modem to replace the Netgear DG834G which doesn't have this LAN address when I disable NAT?

Please help

DG834G is being used as a modem (I've disabled NAT)

FVS318v3 is being used as a router (my goal is to VPN)

I've been allocated two IP addesses with a subnet mask of 255.255.255.252

I can request a block of 8 addresses from my ISP if I can justify to them that I actually need, why I need them, and how many I intend to use over the next 12,24,36 months.

I can now ping both IP addresses from outside but I can only access the DG834G webpage. I cant access the webpage of the other.
