I wouldn't always expect program() to work well for remote hosts but the match() filter seems like it should. Also, I can't tell if $HOST is now being correctly interpreted in 1.6.1 because the message is being written to the wrong place :-) I can say that it does seem to work correctly for other syslog-ng hosts (which I have set up to use TCP), it's primarily the UDP transport that seems to be having problems.
I don't understand how this might work differently than 1.5.26, though I
think the problem is that you have to enable the check_hostname() option
as '%FWSM-6-302' is taken as the hostname (if you enable check_hostname
it will be interpreted as the part of the message as '%' is not a valid
hostname.
I can't remember any changes in this area though.
