Why do I get a SINGLE:MULTIPLE on port 53 from pfSense when client pings it?

[torontob]

Hi everyone,

I have pfSense version 1.2.3 running. On stats I can see this:

udp	192.168.0.1:53 <- 192.168.0.112:57412	SINGLE:MULTIPLE

In Status > Services I can see that DNSMasque is RUNNING. Domain names like google.com and yahoo.com resolve all fine as well.

So, what does the above message mean? and what action should I take to fix it?

Thanks
