Hi, I have a tunnel vpn site-to-site with two ASA5505, the tunnel is up but when I try ping between inside lan I have in log file:
Teardown ICMP connection for faddr 192.168.0.100/0 gaddr 192.168.1.159/512 laddr 192.168.1.159/512

These syslogs do not indicate a problem, in fact they show that an ICMP connection is properly being built and being torn down again, which is normal.
So is the ping working or not?
I do spot one possible problem, you have:
access-group inside_access_in in interface inside
but inside_access_in is not defined anywhere on the first ASA.
If that does not help and the ping still fails, check the syslogs and "show crypto ipsec sa" (to see if encrypt/decrypt counters are increasing) on both sides.

..pheraps the problem are the static route ? I always used vpn based on openswan and in the site-to-site configuration is needful the parameter:
leftnexthop=x.y.y.z
this ip address is the ip assigned to router.
In cisco ASA configuration I have:
route outside 0.0.0.0 0.0.0.0 1.2.186.46 1
where 1.2.186.46 is router ip address and
1.2.186.42
..is the ip address on wan interface of Cisco ASA.
Sorry but I cannot understand where I am wrong ! :-(
Thanks.

Routing seems ok to me.
But as I mentioned already, can you please check "show crypto ipsec sa" on both sides, before and after trying a ping.
That should tell us where it is going wrong
Please also clarify from which side you were pinging, and on which side you took those packet-tracers earlier (and was that with the config from your original post or with the config from your previous post) .
02-26-2010 02:12 AM
I have done reset to factory default valuse and then I have made again all configurations (as the last configuration I sent to forum) and now I do ping with success but unfortunately I understand why in the first configuration I could not ping.
Thanks.
