Currently I have my VPN working fine for external users, but would like to give access to my internal "Guest" users as well.
I know I can enable VPN on the inside interface, but the problem here is that my guests use Google's DNS servers, so my VPN record always points to the outside IP address. I don't want to be forced to setup a new DNS server just for this, or to use different DNS records for when the users are inside.
I would like to ask:
- How can I allow inside users access VPN through outside IP address?
- Alternativelly, how can I make ASA rewrite the google's return DNS record to my inside VPN address?
