Cannot connect directly to internet

In short, I cannot reach the internet on my computer unless I go through my firewall. I have a cable modem with 3 leased ips plugged into the uplink of a hub, which has 3 devices connected to it: my computer, my timestep vpn box, and my firewall computer. The firewall is then plugged into a switch which serves the remaining ports in the house. No computer has a problem getting a 192.168.0.x ip from my firewall and getting on the internet. However, I have 2 computers that cannot connect to the internet unless they go through the firewall. Whenever I try to put one of them on the network with the 3rd leased ip, it cannot ping the gateway. They can, however, ping my firewall and vice-versa. One machine is 98, one is XP Pro. I've even tried plugging them into the cable modem directly and they still cannot ping the gateway. Thinking the 3rd leased ip is bad, I try it on the firewall computer where it works fine. My isp refuses to troubleshoot my machines further as they claim it is a problem with my internal network. Does anyone else have an idea as to what is causing this problem?
 
When you plug a computer into the switch or into the cable modem, is it getting one of the IPs via DHCP or are you manually setting it? Are you setting the proper gateway IP and netmask?

If you're using DHCP, then when the computer makes a DHCP request, your internal firewall is going to respond before the cable provider's does, so you may be getting an IP from the firewall.
 
I have tried it both ways: by assigning the ip statically and by trying to get an ip from my ISP while plugged into the cable modem directly without anything else online.
 
And when you do that, what result? Do you get the proper gateway and other information? Are your 3 IPs statically leased or dynamic?
 
If I try DHCP, I get no ip. It says it cannot reach the DHCP server. If I put the ip, gw, mask in manually, I cannot ping the gateway. I have the option of using either the static IPs or using DHCP. If I use my laptop (running XP Pro) it WILL receive an ip from my isp's dhcp server. If I assign my static ip to my firewall, everything works on the firewall just fine. This seems to be isolated to these 2 computers on my network.
 
No, I have XP's built in firewall disabled and I have not installed any 3rd party firewall.

The 98 box is pretty basic and doesn't have any firewall software installed.
