Some sites are blocked (http)
I have upgraded my system with pfSense-Embedded-Update-1.2-RC3.tgz, first dated 04.11.2007 and now 07.11.2007.
The problem is that some sites are blocked, while some aother are not.
A site I have problem with is:
$: nslookup osdir.com
–- ec2-67-202-28-124.compute-1.amazonaws.com ping statistics ---
30 packets transmitted, 0 received, 100% packet loss, time 29003ms
In the Diagnostics: Show States is see (filtered on ip):

Anyone seen this problem before?
I used pfSense-1.2RC2-full on a AMD TBird 1.4 GHz with 1 GB RAM without any problem.
The problem hitted me when I changed to VIA 1.2 Fanless with 1GB RAM-embedded
Bypassing tha pfsense box, everything is OK.
This is very weird…
The pfsense's CPU is all under 10% usage and memory is under 15%...
I'll try to take it down to RC2 later today
Is this multi-WAN?
If this is multi-wan you need to ensure static routes are in place to send a dns server out to each isp.
