Recently I have set up our Cisco ASA 5505 to use a syslog server running the latest Kiwi Syslog Daemon for logging. The 5505 is set to use UDP for the syslog server. Everything seems to be working and all events are being logged to the syslog server. The only problem I am having is that IP addresses are not resolving to hostnames. I have gone into the DNS settings in Kiwi and set up our internal IP subnet and correct DNS servers for both internal and external subnets. This doesn't seem to have any effect, so when a user accesses a URL, the syslog server logs it as the IP address of the URL and not the actual hostname. Is there a certain way the Cisco should be set up, or the kiwi syslog daemon should be set up to allow this conversion of IP addresses to host names?
