Hi Everyone,

Cisco ASA5520 (Fix IP) ----- ADSL Network ----- Linksys AG241 (Dynamic IP)

Attached files is configuration on both ASA and Linksys. Please help suggest me for the solution.

Chim,

Can you do deb cry isa 100 and deb cry ipsec 100 on the ASA and initate a connection?

If concerned about too much debugs - "debug crypto condition peer ...."

I'm interested to see where negotiation is failing - granted I have not taken a look at the linksys device.

Marcin,

Unfortunately that I forget to capture debug log from ASA. I've only old version of debug log (as attached file) when I first setting up but it different with existing configuration on both ASA and Linksys.

I will continue setup it on 7 June then I will capture debug information as you mention.

Chim,

Indeed messages are not too informative but they indicate a problem wit decoding quick mode messages or similar.

Fresh debugs would be appreciated

Marcin,

I already solve the problem. The problem is I configure preshared-key on wrong tunnel-group. I configured on DefaultRAGroup but the correct one should be on DefaultL2LGroup.
