Hi all,

First of all, i had a create help on the site for configuring the asa5505.
the article "HowTo: Basic ASA 5505 configuration" and "Port config on ASA 5505".
Now i want to setup a VPN Remote Access for extern login on the network. I have configure the ASA 5505 so that the vpn clients can login, using LDAP from our server. The clients get a ip-addres from the pool i have create. but if do a ping to a server in the network, there is no response.

Hi Xenomes,

You forgot to configure the no-NAT rules.
Try the following:

[code:1]access-list nonat permit ip 192.168.100.0 255.255.255.0 192.168.122.0 255.255.255.0
!
nat (inside) 0 access-list nonat[/code:1]

Let me know if this fixed your problem ^^

At first it was not working!
but when I set the
[code:1]split-tunnel-network-list value REMOTEVPN_splitTunnelAcl[/code:1]
It was working and the internet was local.

Thanks for the fast help.
