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

Is your moden set up with DHCP? or, are you able to configure it at all?

At0mic, let me assume a few things:

1) you have a cable internet provider
2) you wish to have both public IPs accessible from the internet

For the sake of demonstration i will assume that your static addresses are
81.92.223.101 and 81.92.223.102

Given these things i would set the equipment up as follows:


Netgear DG834G
NAT OFF
Firewall OFF
WAN interface = DHCP ON
LAN Interface = 81.92.223.101

Netgear FVS318
SUA NAT ON
Firewall ON
LAN interface = DHCP ON (if you wish)
WAN Interface = 81.92.223.102

If that doesnt work then swap the 2 external IPs around and see what happens.

Let me know how this goes
