Externally-Accessible 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) and MSSQL (tcp port 1433).
• File transfer services: FTP (active and passive: tcp ports 20, 21), FTPS (FTP over SSL: tcp port 990) and SSH file transfer protocol (tcp port 22).
• 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).
• Range Three: 167.98.21.80/28 (i.e. the addresses 167.98.21.81 through 167.98.21.94).

In addition (but not required), the Workbooks service delivery team use separate infrastructure and occasionally access from their IP addresses may be useful. These are 87.127.242.44 and 87.127.242.46.
