i have a client, who has been running pfsense since january. i recently

within the site will seem to work fine, but when you try to open another
site, pause.. then opens.
For the sake of the archives - Jonathan sent me the packet captures as I
instructed in a previous reply. It's nothing pfsense-related, it's DNS
on the client machine.
The client machine is doing several AAAA lookups (IPv6) which are timing
out or getting empty responses before doing A lookups (IPv4) for the
domain name. This is adding a 10-15 second delay to every DNS lookup
while all the IPv6 lookups fail. Since your typical page load is going
to make a few DNS queries, incurring this delay several times, it has a
significant impact on page load times. Once the machine queries the A
record as it should have initially, it gets a reply very quickly and
immediately pulls down the web page with no delays whatsoever.
Is this a Vista thing we should look out for? If so, whats the fix
that worked here?
No clue... I haven't heard back since I emailed him offlist with some
info on his captures. I would definitely be interested in knowing what
caused that to happen, hopefully he'll post back.
I'm running Vista and don't have this issue.
