   Hi Folks,   
      
   My situation - I have a home network connected to the internet via a   
   Speedstream   
   EN5861 Adsl router. My home network is further protected by an IPCop   
   (stateful)   
   firewall which sits between the home network switch and the EN5861.   
      
   My laptop runs among other things the Cisco VPN client, which I use to   
   connect to the corporate network via VPN.   
      
   I've just treated myself to a wireless access point (D-Link DWL-2000AP)   
   and a wireless card (D-Link DWL-G650) for the laptop. and have set all the   
   possible security options; I am somewhat concerned however about the   
   security of WEP, given that the keys (128 bit) can be cracked fairly easily   
   using Linux software freely available on the Net.   
      
   What I've done therefore is to build a dual-homed gateway machine with a 365   
   day eval copy of Windows 2003 server, which I've configured as a VPN server.   
   One NIC goes into my home network, and the other NIC is connected via a   
   cross over cable to the wireless access point. The NIC connected to the   
   access point is configured to only accept VPN connections.   
      
   So with this setup, I  connect to the access point using the wireless NIC in   
   my laptop, establish a VPN session using the Microsoft vpn adapter (PPTP) to   
   the Windows 2003 server, which then allows me secured access to all the   
   resources on my home network including the internet. Sweet!   
      
   Everything works fine except the Cisco VPN client software I mentioned   
   early. The Cisco client connects to the remote gateway and hangs while   
   negotiating security protocols. The existing VPN connection from my laptop   
   to my Windows 2000 VPN gateway is then dropped   
      
   I suspect the problem is due to my attempting to nest VPNs. I'm a bit of a   
   newbie to VPN technology so I'm not sure if what I'm attempting (nesting   
   VPNs) is actually possible!   
      
   If anyone has done anything remotely like this before I'd really appreciate   
   any advice.   
      
   thanks & best wishes
