Hi all. One of my regional site is replicating sql traffic to our main sql server located in headquarters. However we receive many fail replication errors. On checking the firewall log i notice the following which shows that my regional sql server fail to connect to my main sql server. There is a deny traffic after the origination connection was teardown. How do i solve this? Thks in advance.

Error Message - %PIX|ASA-6-106015: Deny TCP (no connection) from IP_address/port to

IP_address/port flags tcp_flags on interface interface_name.

Explanation - The security appliance discarded a TCP packet that has no associated connection in the security appliance connection table. The security appliance 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 security appliance discards the packet.

Recommended Action - None required unless the security appliance receives a large volume of these invalid TCP packets. If this is the case, trace the packets to the source and determine the reason these packets were sent.
