Running dual nic cards and would like to utlize them both

I spoke with Comcast and I have purchased a second IP from them, they tell me that entitles me to 2 connections  6mb/768Kb * 2 thats great. Now the question is how do I actually utilize both connections. I know on linux you can set up some type of Load balanaceing but I don't see that feature on XP. Anyone with any ideas on how to set this up? BTW I can monitotr the 2 nicks and see that one of them never gets used.

Unless you have 2 cable modems you will  not get double bandwidth.  

Where are you located and what service do you have?  Usually if you have 2 IP's you are using their new RIP service.  (Chances are your IP's start with 70.88)

If you have the RIP service you will have 2 IP's coming from an SMC or Cisco gateway.  This will not give you double the bandwidth.  Both IP's will share the bandwidth.

Let me know your setup and I will give you the low down.  Here is some info I need:

What device(s) do you have from comcast?

What service did you buy?  (EX. Residential, Workplace Standard, Enhanced?)

What do you IP's that comcast gave you start with?

Where are you located?  (City, State)

I agree.  I think you misunderstood what Comcast told you, OR that the person you spoke to should go back and get an education on exactly what an IP address is, how bandwidth is allocated, and the difference beween the two.

The second IP Address can be used for setting up a DMZ on your LAN, or directing specified traffic from outside your network to something like a webserver, although this is really not necessary if you have a router that can port forward.  To use a second IP Address, you need special devices, and the consumer grade appliances will do you little good.

And, XP cannot manage bandwidth allocation, or Network Load Balancing, although W2K3 can.

And, I certainly hope that your setup (the dual NIC computer) is not directly connected to the internet, without a Firewall or a router providing NAT...  Not a good idea...  And if you are, then how can you connect both NICs to your Comcast Cable Modem, that I assume only has one LAN port?

Perhaps, as savone noted, we need more information on your current setup.

My provider is Comcast and my ips are 66.31.x.x,
 I'm using a Motorola 5100, which does allow the bandwith up to 30 mb,
 I'm connected via a Linksys Switch, and 2 linksys wrtg54gs's routers, an I have Enhanced servvice

And in doing some research if found that you can install the " Windows Server 2003 Administration Tools Pack"
and they state
"Network Load Balancing Manager
Network Load Balancing (NLB) Manager allows you to create and manage Network Load Balancing clusters from a single computer. By centralizing Network Load Balancing administration tasks, Network Load Balancing Manager helps eliminate many common configuration errors.

Using Network Load Balancing Manager, you can configure and manage your clusters and all cluster hosts from a single computer, and you can also replicate the cluster configuration to other hosts.

You can perform the following procedures with Network Load Balancing Manager:

• Create new clusters
 
• Add hosts to an existing cluster and, by doing so, automatically enable Network Load Balancing on that host and and automatically configure cluster parameters on that host
 
• Remove hosts from a cluster and, by doing so, automatically disable Network Load Balancing on that host
 
• Configure all host and cluster properties
 
• Replicate the cluster configuration to other hosts
 
• Diagnose problems with existing Network Load Balancing clusters.
 

As part of the Windows Server 2003 Administration Tools Pack, Network Load Balancing Manager can also be installed and used on Windows XP Professional. You can use Network Load Balancing Manager on Windows XP Professional only to manage Network Load Balancing clusters on remote computers running the Windows Server 2003 family of products. You can not install the Network Load Balancing service itself on Windows XP Professional.

Like I said, you need W2K3 to Network Load Balance...  :)

So then my W2003 Server that controls everything else can utilize Load balanceing, and be controlled by WinXp. Or at least thats how I read it.

Yea, I did not know you had 2K3 in your LAN.  In that case, you should well on your way!  :)

Sounds like you have that part figured out the only problem is, you can not double your bandwidth with one cable modem.  I would for Comcast for over 11 years and this goes against the DOCSIS specs.  If you have ONE cable modem you can only have the bandwidth for that drop.  Also 66.31.X.X is a Manual DHCP address.  If you are using a motorola SB then that means the MAC address of the CPE that is directly behind it (ex. Router) is actually pulling the IP address. You can not pull two Manual DHCP addresses with this configuration.  

Do you have 2 cable modems?  If not you will not need load balancing because you will not have double the bandwidth.  And if you did somehow conspire with comcast to get double the speed it would come through ONE modem with a special boot file and you still would not need load balancing.

By the way,
I see your in MA.  This is what we call the BLACK HOLE.  It is part of the old ATT market that comcast bought.  I understand they do things a little differently up there.  But as far as I know what you are hoping for will not be possible. You can possibly get 2 IP's but you can not get double the bandwidth with one docsis device.q

Savone, you are back on point again.  :)  I agree with your assessment here..
