l2tp vpn pass through

[AliMahm00di]

Hi

We have an asa 5505 in our office and clients inside the office must be able to connect to different VPN servers of our customers with different protocols.

We have issue with servers that uses l2tp and it seems asa won't allow this protocol ...

We have tried a lot of solutions, opening udp500,udp4500 in outside interface etc but none of them worked out.

I will appreciate any help for this issue.

Sincerely

Hi 

Thanks for your reply.

May you please explain what privateIP and pubicIP are? 

We need all clients in inside be able to connect to the server outside but in image it defined host and static nat !

May you please explain more?

Sincerely.

You have VPN server inside ASA and it have IP which is private IP.
the VPN client can access Public IP of VPN server which is config on outside of ASA 
so we first allow connect 
do NAT exception
finally inspect IPSec-passthrough
