Two IPs (internal/external) on PC interface thru WRT54G?

    My wife and I need to access the same corporate VPN, and it won't allow two connections from the same IP. So currently my desktop bypass the WRT54G and uses static address #1. My wife goes thru the WRT54G (wireless connection) and accesses the internet (and corporate vpn) via the router's nat'd address, static address #2. (We have 5 static ip's with our dsl service.)

    That works fine, but it leaves me unable to be in a Windows workgroup with my wife and share files since we're on different subnets: I'm using external static address #1 while she has a private lan address.

    What I'd like to do is to assign two ip addresses to my ethernet interface (easy to do in Windows XP) so I can have static address #1 to connect to the corporate vpn and the internet, and also a private lan address on the router lan subnet, so I can be in a Windows workgroup with my wife.

    My first thought was to plug my pc into a hub. Then one connection from the hub would go to the dsl modem (actually through another hub), while the other connection would go to the WRT54G so I could be on my wife's subnet.

    I'm not sure this would work, and in any case traffic from both ips would show up at both the dsl modem as well as the WRT54G.

    Is there an alternate firmware I could use to help me accomplish this? I don't mind using another hub or router (I have a Netgear RT314) if needed to make this work. Ideally I'd like to have one cable from my pc go to a "special" port on the WRT54G, which would send lan packets onto the lan and everything else out the wan port.

    Thanks in advance!
