   Well this is simple.   
      
   BEFSX41 does not support L2TP.   
      
   You imply that you read the instructions but it seems you did not   
   comprehend them.  Yes, with only Windows 2000 you need to create an   
   IPSEC security policy to connect to this router remotely.  You can also   
   use a VPN client software product, there are a few different ones on the   
   market and you will likely need to figure out the settings on your own   
   since Linksys does not support that.  Or you can get a second router and   
   create a permanent connection between the two from one site to another.   
      
   IPSec and PPTP passthrough are for using a client inside the router to   
   make a connection to another separate router outside of your network.   
   These options have nothing to do with connecting to your VPN router as a   
   VPN endpoint, it only affects connections passing through the router   
   where the router is not an endpoint in the VPN connection.
