remoted linked server problem

I am running SQL 2005 trigger and update the table in remote linked server. This is working perfectly when the firewall is off. However when I turn on the firewall, it wont run any more. I need the firewall on for the security issue. How can I run this trigger with firewall on? Thanks.Do not create triggers that operate outside the scope of their own database.|||Do not create triggers that operate outside the scope of their own database.
