yahoo messenger error capture

[Shady <shadym () gmail com>]

I am a sysadmin of a small network and I am having a problem logging in with
yahoo messenger in my network. I am using pfsense firewall (freeBSD based
firewall) as a premitter firewall in my place and I have the proxy server
turned on in the firewall settings (Squid + SquidGuard). I tried allowing
all website access through SquidGuard and I have opened all the ports for
that particular client just to find if it can connect but no dice. I was
able to successfully connect when I turned off the proxy settings from
internet explorer but that defeats the purpose of having SquidGuard. I
thought of capturing the traffic before and during the login error to check
on he problem but I can't really tell whats he problem since I am new with
network protocols and I am still studying. So what can you tell from that
capture (attached with this email) what could be the problem. Any help is
greatly appreciated.
