I have a high speed internet via a cable modem. I received 2 ip addresses from my provider. Can I use 2 different routers: Linksys and Watchguard Firefox Soho, and still have dhcp enabled on both? Well, you certainly can, but in most cases it only makes things more complicated than they need to be. To actually do it, I'd put a hub in front of the two routers. So your cable modem would go into the hub, each router would be connected to the hub, and each would configured to respond to one of your two static IPs. You could then connect your computers to one router or the other, as you saw fit. I'm just not sure why, in most cases, you'd want to do so. The drawback here is that your machines on one router will not be able to share folders or printers with machines on the other router. Each router represents its own private sub-network on the internet. Multiple internet IP addresses are really only useful if you have multiple computers that you want to access from the internet. For example you might want to set up two web servers, in which case each would need its own IP address. For most common home and small business situations, that kind of setup is actually pretty rare. My ISP has allocated me 5 IP addresses here at home, but I use only one. All the computers in my house (8, I think) are connected behind a single router. I really don't have any need for the other 4 IP addresses at this time. I suspect that, unless you're doing something special, you really only need one of your two IP addresses. It'll certainly be the simplest approach. Related:

on your comment, How can I use two ip addresses from one cable modem, i want to ask if i can use switch instead of hub.
Posted by: Michael at August 19, 2006 10:45 AMI own a duplex, both myself and my tenant are running able modems... other than purchasing a router with two WAN ports to do load balancing, is there a way to amalgate the connections to double my theoretical speed? For instance, and I could probably just spend an afternoon testing this, could I take oen of my spare switches, run both cable modems into it, and channel that into the WAN port of a single router, from there hit another switch, and allow our networks to merge? I can VLAN if I feel the need for security, but I really don't... During the week I use a lot of bandwidth on media applications while they use very little for email and the like... While I'm gone on weekend hikes they play WoW and other online games, so sharing the bandwidth would work out well...
Posted by: Sean at September 14, 2006 7:00 PMCan this also be done with a dsl modem? I know that with a dsl line you usually use PPoE to connect. Our dsl provider has given us 6 ip public ip addresses to use and due to having several servers running we would like to issue each of them a public ip.
Posted by: Chris at November 10, 2006 9:12 AMThe reason why someone would want to do this is to get 2 xbox's on xbox live at the same time in the same household.
Since there doesn't appear to be a way to get two of them to sign in at the same time on the same connection due to port issues.
Posted by: Marshall Leitem at November 21, 2006 3:54 PMHello I have problem with my ISP I need Band Width 512kbps Static IP but he cant provide me. they can give me Band Width upto 64kbps Eight different Static IPs. I wanted to know is there any Software or Device from which i can get help to make by my self a Static IP of 512kbps. Please answer me in detail so i can understand
Posted by: ijlal at December 23, 2006 2:40 PMNo. If they can only give you 64kbps then you can only get 64kbps no matter how many IPs you have.
Posted by: Leo Notenboom at December 23, 2006 3:11 PMLeo, I just read your comments on 'How can I use two ip addresses from one cable modem?' and I have a question. First the problem: two divisions in our company who were completely independent, seperate physical locations, domain controller, webservers... (except for VPN), are moving into our new building together. The long term goal is to have one domain and one network, but my short term goal is to get people back to work. I need to maintane two domain controllers each on a seperate subnet behind one cable modem with 5 static ip address assigned to it. Your solution of a hub sounds easy enough. Is that the best way to share the internet connection for now or is there a better way?

can i change my modem smartax to a different router
Posted by: steven at November 26, 2007 11:41 AMLeo,
I have client software for car washes that require that I use multiple IP addresses, how do I setup my router to use a single cable modem with two separate IP addresses?
I'm using a netgear FVS318.
I alos have 2 connections for credit card processing, 1 for a computer, and 1 for my CCTV system.
Please help, COX is not help, and the company who makes my car wash equipment doesn't know how to port forward, so this is way beyond them!
Thanks
Lou
