vpn and wireless

[ref17]

without any networking knwoledge I am tyring to get my setup at home to work

I have a Netgear VPN firewall connecting to a cable modem.
I can then connect pc(a) to the vpn to gain access to the internet.

I also have a linksys wireless router and another pc(b) with a wireless card. ( Someone else set the config up. )
I connect my wireless router to the vpn and was expecting to have my pc(b) to have access to the internet and I don't.

If I connect the cable from the cable modem ( disconnecting from the vpn ) into the wireless router, pc(b) will have internet acccess and now pc(a) does not.

I would like to have both pc's being able to have access without having to rewire depending on which pc I would like to use.

Suggestions please.

When you have the Netgear on the cable modem and the wireless router behind that, can you ping from the wireless router to the Netgear and vice versa?

It might be simple in that you have the wrong cable - I would expect you to have a crossover from the wireless router to the netgear router.

It might be a bit of a NATing issue. Your wireless router does NAT and then the upstream router (netgear) also does NAT. Working through the addresses should help us diagnose a bit more.

What are the IP address ranges being used?

Go onto each of the routers (netgear & wireless). On each get:

WAN configuration
LAN Configuration

Look out for the WAN connection using DHCP. Also, check the DHCP settings on the LAN connection on both. It may be something simple like DHCP on both routers using the same scope. So the Wireless is giving out 192.168.1.x addresses and the NEtgear is also giving out 192.168.1.x addresses.
