Playing online in Ireland question

Hi, I live in the United States and play PartyPoker and some other sites regularly. I am currently in Ireland and am unable to connect to any poker sites except 2 (ultimatebet and truepoker). Any ideas of what the problem is and what I should do to fix it?

I live in Ireland and can connect to any site, any time. Check if you're behind a firewall etc.
