Cisco ASA5505 L2TP/IPSEC passthrough?

[Sebastian Adolfo Yanez]

Hi there!

I have been trying to establish a VPN connection between Windows 7 Ultimate client and Windows Server 2008.

I am using L2TP over IPSEC and in the middle I have a Cisco ASA5505 with version 8.2(1).

The ASA is doing NAT 1:1 and I have openned udp 500, udp 4500, udp 1701 and IP 50 (esp)

So, this is the diagram:

client---------------internet---------------asa5505---------------server

Any ideas?

Thanks a lot!

it seems that you have the right thing. The traffic flows from inside to outside or viceversa?

Can you paste the sh run access-l from the outside interface in case the traffic comes from outside to inside?

If you test the connection and fails do you have any logs?

outside to inside, got it.
