Network pros: is it possible to have 2 different ip's on 1 connection? - GoFuckYourself.com

clickhappy · 01-26-2005, 09:58 AM

I have a cable model on my computer, and i want to buy a laptop and have that laptop on a seperate ip from my computer.
Can I do that on my current single cable modem, or do I have to install an additional line into the house?

You will need to purchase an additional IP address from your ISP and install a hub. Connect the hub to the cable modem and then your two computers to the hub.

That would be up to your cable company. The typical install uses dynamic allocation of IPs. So you would have to start with dedicated IP service. Many cable companies offer this through their business department. Think some still don't offer it.

For example I have DSL with 5 dedicated IPs. I pay more for the business service as opposed to the home user with DHCP.

You'll need a router in addtion to the modem, Suggest that be a router/firewall with abuiltin Ethernet Switch for your application.

Do you really need a second ip or are you just trying to get both machines online?

It has been my experience at times that it is difficult to get a return phone call from the business end of a cable company. It would be best if you used a company name if you have to leave a message. Been throught it several times for clients. I think once it went smooth without a hitch. This is in the midwest US. Hope service is better where you live.

NAT (Network Address Translation) solves that. Buy a netgear router. I have had problems with lowend Lynksys routers on cable networks (protocol issues).

is that a hub?
Right now i just use it for a firewall and nothing else

pussyluver · 01-26-2005, 10:22 AM

A router will add some protection too. Why not make it a a router/firewall in the same box.

NAT will take your public IP and using NAT provide you all the IPs you could want. Plus those IPs are not routable on the net. Therefore you have some protection.

We could write a short book. Go to the Netgear site to learn about them or do a google search on Network Address Trranslation (NAT) and routers.

If you couldn't have 2 ip's on one connection, no one would have virtual hosting

MickeyG · 01-26-2005, 10:47 AM

exactly what i thought he doesnt need the ips. Just NAT.

you might want to make sure that wifi network is secure since you dont sound too savvy about networking

wouldnt want it getting abused

You don't need to buy a second IP to get that machine online. Buy yourself a Linksys VPN Firewall Router. Extremely easy to configure, you'll be online in minutes.
