Dual Internet links Natting - help

[carl_townshend]

Hi All

I have 2 internet links now from Different ISP's

On my first ISP we have the DMZ with the public IP addresses in so we don't have to NAT.

However as we have a second ISP with a new address block, how is it best to set it up, should we change the DMZ to an internal IP range, then do 2 NATs on the firewall, one from each ISP to the internal address?

what is the best way of achieving this ?

cheers

It is always recommended to use Private IP on internal DMZ zone and NAT with Public IP here in case you have to do twice NAT with respective ISP.

My question is Public IP block is provided by ISP or it is own by you.
