Greg, My corporate f/w is allowing port 13 in outbound direction. In the ISA I have created two Packet filetrs for TCP and UDP in the Outbound direction with Local Port as All ports and Remote port as Fixed Port 13. However, my sync fails, unable to access port 13. Any suggestions? Thanks. Regards, Raj -----Original Message----- From: Greg M.
