I've got this message

%PIX-6-106015: Deny TCP (no connection) from 10.220.4.110/3999 to 10.219.65.91/ 25689 flag ACk interface outside,

When I tried to connect to a device out of my network, the rules into the fw are ok, any comments?

PD

My PIX is a Cisco PIX 515 Firewall Version 6.3(3)

This message is logged when the firewall discards a TCP packet that has no associated connection in the firewall unit's connection table. The firewall looks for a SYN flag in the packet, which indicates a request to establish a new connection. If the SYN flag is not set, and there is not an existing connection, the firewall discards the packet.
