CISCO ASA 5512-x Syslog Issue

[kyawhtinwin]

After an update to the new Syslog server, I am not able to see ASA Syslog on my firewall.

DR Firewall extranet interface sends Syslog to log server, then verify traffic from production firewall.

DR firewall interface is linked to Production FW one of the interfaces.  What is a possible issue?

Best Regards,

Since you don't mention any changes done on the ASA side it is unlikely the ASA stopped sending messages. However you can certainly perform a packet capture for the messages leaving the ASA and with the syslog server destination.

If you confirm the packets leaving the ASA, then similarly capture the packets arriving at the syslog server from the DR firewall Extranet interface.
