Level 1

Hi all,

I'm very new for ASA. My current company wat to setup VPN to user to access internal. So now I'm trying to setup VPNauthenticate with my NPS server. The VPN can connect and acess outside network but cannot access internal network. Would you please help me to solve this?

My additional option :

1. I've cisco WS-C3650 connect behind firewall and has VLAN routing. 

2. My client VPN IP address use some IP from VLAN 120 (internal VLAN).

3. I've site-to-site VPN connection and VPN client and access site-to-site from current setting.

4. My ASA is 9.3.3 and  ASDM is 7.5.

Here's my current config

Many thanks in advance.

Hi pongsiri_chu

The NAT-exception seems to be missed from the configuration. 

Based on your configuration , you can create a simialr entry as follow:

nat (any,outside) source static VPN-LOCAL-205 VPN-LOCAL-205 destination static VPN_Pool VPN_Pool route-lookup

Hope it helps

-Randy-

Hi rvarelac

Thanks for your reply. I can make it acces inside by add this command

nat (outside,inside) after-auto source dynamic VPN_Pool interface

Thanks for your help.
