(Please bear with me, I have little firewall or Cisco knowledge, but 
have been charged to make this happen)

I've got a Cisco 2801, with the firewall feature set. I've got a 
client-side VPN configured (by the vendor). By client-side, I mean 
connections by the users from home or wherever, using the Cisco VPN 
client. I can make the connection, but I need to modify and extend it a bit.

Problem 1 - when I do connect from my laptop at home, I lose 
connectivity to my local LAN resources (such as local shares and 
printer), even though I have "Allow Local LAN Access" checked off in my 
client config. I believe from my research that my problem is that I 
don't have split-tunneling turned on, in the router config.

The router VPN config looks like this (in part; there are other 
site-to-site VPNs defined, as well):

VPN addresses are 172.16.1.x
Corporate LAN = 192.168.1.x

================================================
crypto isakmp client configuration group VPN3000
  key ******
  dns 192.168.1.9 192.168.1.241
  wins 192.168.1.39
  domain mycompany.com
  pool contrib
!

ip local pool contrib 172.16.1.1 172.16.1.255
crypto map VPN 999 ipsec-isakmp dynamic DYNAMICMAP
================================================

But I'm confused on how to construct the ACL. And I have no 
documentation for my 2801, or for IOS. I know I need to add it in the 
VPN3000 stanza.

Can anyone clue me in on how to make this split tunnel ACL work? There 
are ACLs in the config, that both permit and deny to the 172.16 and the 
192.168 address spaces, but how they fit into the picture, I don't know. 
I know that I can ping and access any 192.168.1.x address when I 
connect, and that I get assigned a 172.16.1.x address when I connect.

Problem 2 - I am not prompted to log into my Windows AD domain when I 
connect. I am prompted for a local ID and password (defined in the 
router config) when I connect. I need to be prompted for an AD ID and 
password. I believe I need to point the router config at an aaa server 
on my LAN (which is a Win2000 Server running IAS). But again, I am lost 
as to how to specify this. A complication is that I already have a 
site-to-site VPN defined with a business partner, and I *can't* take any 
chances with that going down, for any reason. But since that's working 
now, and is not dependent on any AD ID, my entering a "aaa server" 
command shouldn't affect this other tunnel, should it?

I realize I'll probably need to provide more details, and I'm happy to 
do so. And I appreciate any help anyone can give me on this project.

Thanks
