VPN through VPN

By synthesist ·
My AT&T digital broadband uses a VPN connection to WorldNet as my ISP. The AT&T server does not recognize or route to IP of my company VPN.

home PC VPN DUN client ->Intel AnyPoint phone line-> tranceiver==>wireless==>AT&T tower->AT&T server->Worldnet IP->Internet

VPN session between home PC and Worldnet MUST be used.
Is there a product or configuration to provide a VPN client USING the original VPN client to permit VPN from home PC, through the VPN to WorldNet, to my office VPN IP?

you will have to contect your ISP to make sure that they did not block tunneled TCP/IP packets, after you call them up and they say that they let tunneled data thru try other things b/c it might be that the block it on thier routers.
as of the problem of using a vpn thru vpn i have done this befor where my only connection to the internet was only a vpn connection to my ISP and I was still able to connect to my office network thru VPN.

Nice try, but not the answer.
Unfortunately my connection is not directly to the ISP - it is through the AT&T HSD (High Speed Digital) server via VPN to the ISP (WorldNet). Per your answer, tried a dialup connection to WorldNet - it does allow theVPN to my office, so it isn't blocked at the ISP point of presence. But I have to use the VPN over the HSD TO the ISP. (Which proves that the HSD connection supports tunneled packets..) I just can't find a way to pass a tunneling packet (to work) embedded in the tunneling packet between me and WorldNet...

Now I dont get it, is your problem that after you connect you cant send packets to world net?
or that you cant send packets to your company?

Your comments about trying multiple IP connections led me to the routing table. I tried using ROUTE to specify a "static route" to force the sequential connection. Unfortunately, since both the AT&T VPN to WorldNet and my office VPN assign my IP using DHCP, there was no ROUTE ADD command that could script the connection.
