VPN behind NAT

Hi All,

I am using vpn client 3.x version connect to concentrator. I am able to connect and succesfully autenticate behind Nat. After that i am not receive decrypted traffic. I could see in the status bar outgoing traffic are encrypted passing through vpn. but i am not receiving the same from other device. Same workstation if i tried from ADSL connection (behind NAT) it works. I just wondering if the NAT-T not enabled on the concentrator i wont be able to connected through ADSL aswell.

Can any one help me...

Thanks in advance

Re: VPN behind NAT

If NAT-T is disabled, You would be able to connect, but will not be able to pass traffic.

Enable "IPSec NAT-T" on the concentrator.
