One router, 2 PC's & 2 IP's?

**consumertalks** · January 11th, 2004, 04:00 AM

Quick story:

Cable modem w/router/firewall. My job has me connect to their IP and had me set up my home PC the same way. But when their ISP was down a bit, that meant I couldn't connect on my home PC.

Can I have my home PC set to the IP Comcast gives me, and my work PC set up to connect through their server, both going through the one router?

If not, how can I set it up so I have two different connections? Without a second modem, of course. Thanks!

your moden will only connect to one isp, that being the one you have the account for, if you have wxp-pro and your work place has a remote access server , you can connect to that server if the account is already set up for you.
the work place has paid for the two isp's address, you can do that also but it would require a second modem and another router.

I have 2. The one I pay for, and my work. Can't I set my home PC to connect through a different ISP?

if you have winXP Pro at home , you can set up an alternate network config for your one nic.

go to the properties for the nic,then tcp/ip properties,then alternate config tab

Like said above. One IP to one acount. I just setup one of those linksys wireless routers yesterday. Point of router is to take ONE IP from ISP give it a network IP on your domain then you'll be able to connect t that IP from anywhere there. You basically want remote aceess to that unit? Is that what you are saying?

DUH. Now I getcha. No. You can BUT your work account must have your PHONE # setup for there IP. DSL must have the phone # registered to send you the dsl service. Your work can-if the setup that account as TWO accounts. Only way. Cause one single user account gets turned on ONE phone #. THat answer it?

Ace- I have two PC's, so I have two NIC's. Not one.

Xtreeme-No remote access needed.. you lost me! And it's a cable modem, not DSL. No phone #'s or anything are needed.

This is getting beyond way what my question is.. let's try this a little simpler.

I have two computers. Each computer's NIC is plugged into a Cisco Firewall like this. This is then connected to my cable modem. Can each computer connect to a different IP? I'll worry about who pays for what and all that.

It's like two TV's connected to the cable outlet with a splitter. Each TV can be on it's own channel.

So this is my only question. --> If I change the settings on my home computer, going through the firewall, will it connect?

if you have the model with two wan ports then yes as long as you also have two modems

your modem has only one wan output which will be one isp address, you will need a second modem for the second ip address and both modem can connect to the firewall router as long as it has two wan input ports.

Cable router WAN ports are designed for one WAN IP....

To use two ISP ip addresses.... just have your cable modem go directly into a hub/switch and then connect two routers to the hub/switch.

Each router can pick up a seperate address from the same cable modem as long you're registered to by your ISP.

Only problem is you'll have two networks that cannot be interconnected without running into DHCP/DNS problems. You'll have to physically connect your pc to one router or the other unless you don't mind having two nics in every pc on your private network. The onyl way to aviod this is with a smater and more expensive enterpise router that accepts multi WAN ports.

Also, even with two seperate IP addresses/routers .... they share the same bandwidth and ISP reliability. If your ISP goes down then you'll loose both IP addresses.

Considering the extra cost with little benifit and extra work.... you might be better off just allowing your work to pay for your access and save money by not getting another personal address.

Yep. Need two modems OR duel WAN port modem ($), sharing DSL and Cable = about the same so that didnt really matter much but I was going on about dsl hehe. Both are gonna need a Router/switch to share the connection amungst pc's and the networking is near identical. Only diff is on modem end. Sorry. Did we answer your question?

talk to you're IT guy at work, get him/her to come over to have a look to see what he/she can do you for you..

you'll need external account permissions so you can login to work from home, that's purely network admin's job..
as for accessing your home network from work that's a bit trickier though it can be done...

if you bring home a laptop from work i would suggest having 2 user access accounts for it 1 with home network setup and the other with work network setup, then setup a file sharing area where both accounts can access the work data from...
