cable modem with router with separate IP address

okay, i'm about to go over to my bosses house. he has 2 computers connected with a cable modem and a D-link router. both can get on the internet, no problem, BUT he just paid for a second IP address. the reason is because he wants two diff. email accounts using cox. i've got a cable modem at house with just one IP. my question is do all i need to do is set up that 2nd computer by typing in the computer name and workgroup, like @home. it still should be able to connect through the router, right? and then just set up the email account.

If he’s paying for a second IP address, is it static? (if not it should be – my .02)
If so, why not just configure the network settings manually?

if the router is running dhcp it should already be serving both the machines an internal ip while it takes the one for the @home account.

most @home providers give you 3-5 e-mail address per IP. check with the provider, he may be paying for nothing if he's only currently using 1 e-mail address.

Damned Angel is right. I've never seen a cable modem provider that only allowed one email account. However, just in case this is the first, you don't need to change any settings for the two computers to use the cable account. The only settings you will need to set to differentiate the two email accounts are the individual usernames and passwords you will enter into the respective system's email software.

NOOOOOOO!

Do not give the computers the same name!!! They will not communicate. They must have the same workgroup name like mshome or workgroup or whatever you want to user but the names must be different.

If the cable modem provider provides more than 1 e-mail address and you have a router all you need to do is set up his mail program to get on to the appropriate mail server with the individual password like [email protected] and [email protected]. you will need the smtp and po3 server names and cox will have them. With cable modems you should be getting something like 2 to 10 e-mail accounts depending on your carrier. I have never heard of cox so who knows. You shouldn't needa second IP for this and please note the cable company people are told to push the other ip's so they can make $$$.

Anyway, the router takes on the IP and creates a subnet for you and all you need to do is have the computers set to obtain IP automatically connect using a DHCP and they should have full internet access after that. Setting it up like this makes the computers pull an IP off of the router.

Good luck.

I'm on Comcast, right on the boarder between Cox and Comcast. Comcast gives us either 7 or 5 email addys, and I believe Cox is the same. I'm about 90% sure they will give the same number of addys. Remember, using the router will technically viod the agreement with the cable company as you are not supposed to network on a cable modem. (Unless you pay for the business I believe) So, because of this, they will definately attempt to sell another IP when you call them up and ask..."I want another email account on my second computer." Unless he's already using all his address' it's another example of the man trying to squeeze another penny out of us the consumers.

Are you sure? My cable guy set my router up with me and told the company that he was doing so. I think they just don't support your LAN for you. I know that if you run services from you home like IIS or FTP server they get a little miffed and that's against the rules.

DO NOT give them the same name. If he has a router he should not be paying for another IP address that is what these things are for, they assign addresses. The provider (I dont care who it is) is ripping him off if they are only giving him one email address. Try this:
1)Contact the provider and get the host and domain name.
2)BEFORE configuring the router change the net settings to ex. User: Room 1 Workgroup: @home
3)Enter the the domain and host name in the router setup (ie. if using Comcast - Domain cc66453, Host: anywhere.comcast.com)

I've used the same user name on the router and the PC and it hosed the router. If the provider is not giving him more than 1 email address, have him log onto Lycos,Hotmail,MSN.com, etc. to provide another email address for the account. More than likely the provider DOES NOT want him using a router (doesn't want to lose the IP address revenue). I have done this a thousand times, if you need help email me! Good luck!

Yeah take my word for it. Routers will do it for you. Keep the WORKGROUP name the same but the computer names MUST be different. Load NetBeui to see the local computers.... don't forget to share your resources so I can hack into your PC and steal all your porn .... :D :D :D

No, this is not the way to go
You have comcast, with the RCA modem, I'll assume
the modem is capable of routing without a router, just hook it up to a hub
what happens when you buy another IP from comcast, they will give you a *second* computer name
computer A gets one computer name
computer B gets the other computer name
there is no email user ID and password, your accound is found by the computer name
so CC192343-34 will be [email protected] and CC192343-35 will be [email protected]
The router only gets one computer name, and because you need to get email from two seperate accounts, the router must be removed from the network and replaced with a hub for this particular setup to work the way you want it too
i'd network with ipx, and take off the binding for file print sharing from tcp/ip so you're not broadcasting your needs over the network
other than that you should be fine, but you can't use a gateway if you have two computer names

The router will do it for you, technically the ISP (Cox, Comcast, ATT, etc.) wants you to call them so they can charge you a monthly bill for a second IP address, thats why they made routers....anyway, your boss or yourself can add up to 5 (I think for Cox) emails by going to the ISP "home-members" site and "adding" an account. It takes a little time on the web-site and in Outlook Express, setting it up, but it can be done without contacting Cox. If he has the origianl manuals when he had the cable modem installed, it will explain it all in there. Good Luck! :D
