I recently updated our internet server, and when we reinstalled, the isa server is not allowing internet traffic on the subnet that the wireless routers are on

I would recommend that you have a moderator move or you repost this question in the Forefront Edge Security - General Forum, which includes topics related to ISA. http://social.technet.microsoft.com/Forums/en-US/Forefrontedgegeneral/threads Visit: anITKB.com, an IT Knowledge Base.
