Because of the substantial costs involved, whereverpossible, B-end (i.e. school end of the fibre) shifts should be avoided.For the technically minded, there are four schemes under which a school’s computers can beallocated IP (Internet Protocol) addresses:OPTION 1 - LGfL supplied private address rangeThis option provides a school with a range of private IP addresses. LGfL provides up to 6 “ClassC” ranges of 255 IP addresses per connection. These ranges can be allocated across thenetworks according to your requirements.OPTION 2 – Public IP addresses with school’s own managed firewallThis option is suitable where a school would wish to have total control and responsibility fornetwork security. LGfL will supply the school with a quantity of public IP addresses for use on itsfirewall. 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 3 - Retaining existing IP address rangesIf a school wishes to maintain their existing IP address scheme then, in most instances, this canbe accommodated by use of NAT. If a school has multiple networks LGfL will provide dynamicNAT, such that each network will appear as a single IP address to an external site. LGfL willprovide static NAT for devices that need to be externally accessible, such as web servers orSMTP email servers. Firewall policies to protect access to such devices from the Internet areprovided by the WAN (wide area network) Management and Security service.OPTION 4 – School’s own public IP addresses with your own managed firewallThis option uses the schools own public IP addresses. To use this option the school must haveprovider independent public IP addresses assigned directly.8
