Externally-Accessable Services

The set of services permitted using 'External Access' are:

• Web services: HTTP (tcp port 80) and HTTPS (tcp port 443).
• Email: POP3 (tcp port 110) and POP3S (tcp port 995); IMAP (tcp ports 143, 220) and IMAPS (tcp port 993).
• Database services: MYSQL (tcp port 3306).
• Network services: DNS (tcp/udp port 53) and ICMP ping (echo-request).

Regardless of the 'External Access' setting scripts can send email via the Workbooks API; emails are sent using the user's Workbooks Email Configuration.

Configure any firewalls protecting these services to accept connections from the Workbooks Service's IP address ranges:

• Range One: 80.69.20.160/28 (i.e. the addresses 80.69.20.161 through 80.69.20.174).
  
• Range Two: 89.187.105.224/28 (i.e. the addresses 89.187.105.225 through 89.187.105.238).

In addition (but not required), the Workbooks service delivery team use separate infrastructure and occasionally access from their IP address range may be useful. This is 92.54.142.224/29 (i.e. the addresses 92.54.142.225 through 92.54.142.230).
