Hello,
I am configuring an ASA 5505 for remote users to access a network. VPN users can authenticate against the domain controller, connect and obtain a vaild IP. The local DNS server is resolving domain names for the users as well and the remote users can access all systems behind the ASA. Users are not able to access the internet once connected.
The config is posted below does anyone see anything funky?
