guess that traffic is getting NAT'd out, and not hitting the tunnel (by
the way, you probably only need debug crypto ipsec 5, not 100...)


Do you have NAT setup on the 5505? If you do, do you have a NAT exclude
ACL setup that excludes "your device networks -> remote device networks"?

hello eveyone,

first thanks everyone who replay on my post.
I can't established SA, crypto acl is the same on both ends, well they tell
me so. I can't see config on other side but maybe from log that i can se on
my ASA i think that problem is on my side. I realy don't know maybe problem
is in licence (10 inside hosts) but i have only 2 inside hosts
(192.168.11.11 and 11.12).
I will try to apply crypto acl with ip rule and see what happens.


I think this was previously mentioned by Paul Melson... try to use IP
addresses in your IPsec interesting traffic ACL... I agree with him, that
having specific ports in ACL1 is the problem, as far as I know

So ACL1 is now:
access-list ACL1 extended permit tcp host 192.168.11.11 host 10.1.100.13 eq
4000
access-list ACL1 extended permit tcp host 192.168.11.11 host 10.1.110.250 eq
4000
access-list ACL1 extended permit tcp host 192.168.11.11 eq ftp host
10.1.100.105 eq ftp
access-list ACL1 extended permit tcp host 192.168.11.11 host 10.1.100.105 eq
ftp-data
access-list ACL1 extended permit tcp host 192.168.11.12 host 10.1.100.13 eq
4000
access-list ACL1 extended permit tcp host 192.168.11.12 host 10.1.110.250 eq
4000
access-list ACL1 extended permit tcp host 192.168.11.12 host 10.1.100.105 eq
ftp
access-list ACL1 extended permit tcp host 192.168.11.12 host 10.1.100.105 eq
ftp-data

ACL1 should be:
access-list ACL1 extended permit ip host 192.168.11.11 host 10.1.100.13
access-list ACL1 extended permit ip host 192.168.11.11 host 10.1.110.250
access-list ACL1 extended permit ip host 192.168.11.11 host 10.1.100.105
access-list ACL1 extended permit ip host 192.168.11.11 host 10.1.100.105
access-list ACL1 extended permit ip host 192.168.11.12 host 10.1.100.13
access-list ACL1 extended permit ip host 192.168.11.12 host 10.1.110.250
access-list ACL1 extended permit ip host 192.168.11.12 host 10.1.100.105
access-list ACL1 extended permit ip host 192.168.11.12 host 10.1.100.105

At least try this config, and see if it works... worst case roll it back to
what you had before.

Do a 'debug cry isa 5' and try to ping a remote host from e.g. 10.1.100.13
and see if the tunnel tries to build
