Cisco ASA 5505 VPN & Default Gateway problem

Asked by erkki01 in Virtual Private Networking (VPN), IPSec Security Protocol, Cisco PIX Firewall

Hi!

I've been playing with Cisco ASA 5505 for 2 weeks now. I've been trying to set up an VPN remote connection to my friend without no luck. First I wasn't even able to make the connection. Now the connection happens, and I can get IP address for my friend's remote computer, but the remote machine doesn't get Default gateway settings. Also it's netmask is 255.255.255.255.

Because of this, I think, it's impossible to get the remote computer access my network. How can I fix this with ASDM interface? I'm using ASDM ver 6.2. The chart how to connect is as follow:

Local network
Internet access via ppoe - Cisco - local lan computers

Remote network
Internet access on windows machine.

Connection able to establish: L2TP, MS Chap V2, IPsec: AES 128, compression (none) PPP multilink framing Off, Client IP comes fine from Cisco, Server IP is my internet IP address, NAP State not capable.

The remote computer gets connection but IPv4 shows no internet access and on IPv6 row there's mention no network access. (on window's connection status, general page).

Also, it shows on remote computer that no DHCP is enabled, altough the ip address is gotten from ciscos IP pool for VPN conenction. NetBIOS is enabled. I have also forced DNS servers to these I use to connect internet. Wonder if this is ok. Remote VPN connections are only intented to access my local area network, they still would use internet by their own internet connection.

Do I need to add a static route of some kind? How can I have Default Gateway pushed to the remote client? My Cisco server ip in lan is 192.168.1.1 and remote gets ip 192.168.1.90 (to 99). My local network is under DHCP and gets ip from 192.168.1.2 (to 10). My internet connection is configured by ppoe for internet default gateway and dns servers and ip address.

Also, what's the deal here that I cannot use other than 3DES or AES-128 with windows built-in client (have not tried any other either). And if I disable 3DES, I cannot even establish the VPN connection. :)

thanks!
