Hello Shabbir,

First , your question is not clear enough to know what to check in your configuration output. But if you are trying to configure L2TP over IPSEC , then your configuration to me looks fine from ASA perspective .

Also , can you confirm that you have manually put an inspection in place for the traffic in terms of ports s e.g 50 ,51 ,4500 . Please also check NAT configuration (e.g. crypto isakmp nat-traversal ) , but most important is the ports inspection by default this is not inspected.

If all above is correct . Can you send over packet tracer output for the interested traffic.
