Option 2 OPTION 2 – Public IP addresses with school’s own managed firewall This option is suitable where a school would wish to have total control and responsibility for network security. LGfL will supply the school with a quantity of public IP addresses for use on its firewall. The quantity of IP addresses supplied will be based on the current and expected usage. All firewall policies and Network Address Translation (NAT) are the responsibility of the school.
Option 2 Does not have MIPS or firewall rules on LGfL 2.0 firewall. Access to all LGfL 2.0 services where possible. – VMB Network Statistic Portal instead of on LGfL support site. (1 day course) – No Email relay & No outgoing MailProtect without conforming to port 25 rules. (See next slide.)
Option 2 Mail Server If a school based mail server is hosted on Option 2 which means it has a public IP, it can receive and post email on port 25 going to and from the Internet given the schools firewall rules allows it to and the schools dns server points the mx records to the school based mail server. After the schools domain is configured on the LGfL email content control, If the school wants to use LGfL email content control for incoming scanning, it changes the schools dns server to point the mx records at the LGfL email content control. The LGfL email content control then delivers to the school based mail server via its public IP address. The schools dns controls which way mail is delivered into the school. The school based mail server and the schools firewall control the mail route out of the school.
LGfL 2.0 Option 2 Advantages Complete control over all ports interacting with the internet. No waiting for firewall ports & MIP configuration. Closest thing to ‘Raw Internet’. There is only one return path from the internet. Maybe easier transtion for LGfL1 Option 2 schools.
LGfL 2.0 Option 2 Disadvantages Complete exposure of all ports interacting with the internet and other Option 2 LGfL schools. Attack Bandwidth from other schools will be the smallest of bandwidth of both schools. Attack Bandwidth from the internet will be the bandwidth of the school. Restricted access over Janet UK due to Janet UK policy.
