Could Not open some sites from Windows Vista and Server 2008 when using FreeBSD as gw

[Dennis Melentyev]

Hello Vladislav,

As Jeremy stated, it's too little facts to analyse.
What does tcpdump show, what are the PF rules, proxy settings,
authentification, etc.

Just wild guess: is it IPv6 running on MS stations?

PS. You might have more help from Russian/Ukrainian speaking UAFUG maillist.
