I'm not a Cisco PIX internals expert, but in TCP built (302001) I got an 
inbound|outbound so I can identify who start the connection.

If (302005) shows only the connections FROM foreign address TO local one 
(as Cisco says) , how someone could identify the connections FROM local 
address TO a foreign one ? 

Maybe I'm missing something ? 
I've not found in Cisco System Log Messages Guide any other message about 
outbound UDP built( all links for pix are here 
http://www.cisco.com/en/US/products/sw/secursw/ps2120/products_system_messa
ge_guides_list.html ).


Thanks again

P.S. Naman shows me that in PIX v6.2+ there is a different message for UDP 
Built with inbound/outbound indicator, so I have to 'assume' that maybe in 
PIX version 6.0 it was a Cisco matter the absence of a direction indicator.

The question remains...I have to get all 302005 as messages indicating 
ONLY connections from foreign address to local ones ?
There is no indicator for an UDP Built from a local address to a foreign 
one ?
Or the Explanation should be :

Explanation   This is a connection-related message. This message is logged
when a UDP connection is started to foreign address faddr using the global
address gaddr from local address laddr, or when a UDP connection is 
started from foreign address faddr using the global address gaddr to local 
address laddr.

?

Hi Verde,

You know in my opinion Cisco has one of the best support sites in the 
world.
I don't believe there is a single product that can't be deployed using 
only
their website.


Example of what you asked for:

Log Message %PIX-6-302005: Built UDP connection for faddr IP_addr/port 
gaddr
IP_addr/port laddr IP_addr/port

Explanation   This is a connection-related message. This message is logged
when a UDP connection is started to foreign address faddr using the global
address gaddr from local address laddr.
