Routing to net beyond LAN through VPN

[aquila125]

Hi all,

I have about the same problem as this one:

http://www.tek-tips.com/viewthread.cfm?qid=1396158&page=2

I have a 192.168.40.0 255.255.248.0 network that is accessible through VPN. On the inside network there are a couple of other networks (other locations) eg: 192.168.24.0 255.255.248.0
Now the vpn users should be able to logon to the 40.0 network and connect to the 24.0 network, but I don't seem to get this working. (both netmasks are 255.255.248.0)
The firewall the VPN users connect to is an ASA5010 and we'r currently using a PIX501 as router to the 24.0 network (test setup).
Connecting from within the 40.0 network to the 24.0 network does work, just not from the firewall or from a VPN connection.


this is our setup:
INTERNET - ASA5010 (212.35.X.X/192.168.40.2) - LAN 1 - PIX501 (192.168.40.1/192.168.30.1) - LAN 2


This is our config:

You need to change your VPN pool to a subnet that doesnt reside on your network and then fix your nonat access-lists.
