Please can someone help with the following; I have an ASA 5510 running v8.4(3)9 and have setup a remote user VPN using the Cisco VPN client v5.0.07.0410 which is working appart from the fact that I cannot access resources on a secondary subnet.
The setup is as follows:
ASA inside interface on 192.168.10.240
VPN clients on 192.168.254.x
I can access reources on the 192.168.10 subnet but not any other subnets internally, I need to specifically allow access to the 192.168.20 subnet, but I cannot figure out how to do this please advise, the config is below: -

Hi Simon,
Please try this and let me know.
nat (inside,any) source static 20_range_subnet 20_range_subnet destination static obj-192.168.254.0 obj-192.168.254.0
Let me know, if this helps.
thanks

Hi Rizwan,
That worked, thanks so much, can you give me an explaination as to what the line is doing that you specified please???
Cheers

Your config was missing a no-nat between your "192.168.20.0" and "obj-192.168.254.0"
So, if you look at your config there is a no-nat for inside subnet "obj-192.168.10.0" as shown below.
nat (inside,any) source static obj-192.168.10.0 obj-192.168.10.0 destination static obj-192.168.254.0 obj-192.168.254.0
So all you have to do is create a no-nat for your second subnet, like I showed you before, the solution was already there on your config but I guess you over looked at it.
I hope that helps.
Thanks
