Firewall Rules

Below is a list of traffic that will need to allowed through the bookstore firewall for access to TCS systems. We also need to know the forward facing IP that bookstore traffic comes from in order to enable certain processes. Primarily for SFTP access to import any course adoption records, student accounts, etc. that the bookstore may need to import in bulk.

I’ve added the URLs in case your firewall supports URL based filtering.
