DNS resolution slow on first lookup
-
Hi,
This may be pretty n00b, but I couldn't find too much on this problem via the forum search, the documentation, or Google, so I figure I did my official n00b search ;-)
Here is the issue: I have PFsense set up pretty much as an out-of-the box post wizard configuration running on a Soekris net5501 running the 1GB CF card installation. The firewall works awesome. Very nice piece of work. However, the one thing I have noticed is that the initial hit on a web page seems to take 6-10 seconds to get a response. Firefox alerted me that it was in the midst of looking up a site. Hence I went to a terminal on a client machine and did an nslookup of some random real domain. Sure enough the DNS lookup took 6-10 seconds. Subsequent lookups on that domain returned immediately due to the DNS cache. I decided to take this a bit further and tried logging into the SSH shell on my pfsense box and try the nslookup there. Exact same problem. Since I run my own DNS on a Linux machine internally for our company, I tried the nslookup on that machine and it was very fast… usually .2-2 seconds for the initial query (pre-cache).
Is there anything I can do to pfSense configuration to have it return faster for initial queries? Thanks in advance for answers.

Did you configure your internal DNS server on "system –> general setup" ?
Did you also uncheck the box: "Allow DNS server list to be overridden by DHCP/PPP on WAN"

I've found that it doesn't even auto-configure DNS anymore since the last few nights' updates so this might be related.

DNS from DHCP should be fixed with any snapshot from late Saturday on.
