Hi!
Could someone explain me this log?

Deny inbound (No xlate) tcp src outside:12.47.197.fff/25963 dst outside:xxx.ddd.ccc.zzz/389

how is ti possible that the source is outside and the destination is outside too?

ThankYou
 
The message is basically telling you there is not a Global or static rule in the firewall for address xxx.ddd.ccc.zzz, and someone is attempting to contact that host.

The fact that both the source and destination address are outside is legit in the warning, because the PIX treats static and global assignments as "outside" addresses (in other words, if you do a "static(inside,outside) 192.168.1.1 xxx.ddd.ccc.zzz", 192.168.1.1 is the inside address and xxx.ddd.ccc.zzz is the outside address).

All that does not mean you should add a global/static to make the above message go away, of course. From the looks of it, someone is trying to contact a host of your via LDAP (the "/389" is the destination port, which is LDAP). My guess is someone is doing some sort of scan to see what's open, and you firewall is correctly dropping the traffic.
