Live Streaming - problem with two pfsense boxes

[Nachtfalke]

Hi,

a colleague of me has to use a live stream. there is a testing site and he cannot pass the test.

http://live.time4you.de/ibt/acso/area=site/style=booky/paint=yellowblue/btn=i50/diction=acso/de/sys/sico/lico/public/check/start.xhtml

On the right side the is "Live-Content-Streaming".
After clicking on "Ausführen" there should appera a new line every second. If this isn't happening and all lines appear after 15 seconds than there is a "problem" with the firewall.

I am using two pfsense. pfsense1 with LoadBalancing and pfsense2 with squid (transparent mode).

I bypassed squid for the clients source IP, I do NOT use LoadBalancing for this client on pfsense1.
I changed bothe firewall to "conservativ" but with no success.

What could be the problem if there is one ?
I cleared the browsers cache, tried with FF6 and IE8.

Thanks for your help.

Hmm, I tested it at home with my small home router and the same issue.
so I don't think it is related to pfsense, squid or loadbalancing.
it's just the damn webpage ;)
