Need additional public IP to do NAT on my second VPN pass-thru tunnel

Does your IP need to be static? If so, I would suggest Cox Business, since thats the only way to get a static IP. The other way would be to pay for Multiple Computer Access (MCA) which is a service that allows for multiple dynamic IP's. Or, depending on your area, you could upgrade to Ultimate which includes the 3 DHCP. 

Also, how do you plan on networking it? Will you be using a switch in between modem and VPN or does your router have multiple interfaces with separate WAN IP's? 

Thank you. I have Cox High-Speed Internet - Premier Package It looks like I can do 3 dhcp, good to know. I have switch, and second router , etc so 3 dhcp should be more than enough.

Unfortunately, no. I think your looking at the MCA website and seeing where it shows available(max) IP's, not how many are assigned to your account. MCA is a service you pay for which allows the additional IP to bridge. Basically you get I DHCP IP per data service (account) free, everything else cost extra unless you have Ultimate Tier.

Thank again, You are right, it says Computers Active 1 , Computers allowed 3. And there is option to Add Computer. So you are saying I can add 'computer' (vpn router in my case) and get IP address assigned from DHCP without paying yet ?

When trying to Add Computer it says:

You are about to add a computer to your romaniuk@cox.net account and incur an additional monthly fee

No, the opposite. You get the IP that your using now, like normal, anything beyond that cost extra. Thats why its saying its going to apply a charge. Your probably better off calling Cox and talking with their sales department to get exact pricing first. Also, sometimes doing via the website is glitchy. 

Sounds good , will talk to sales
