Phased Service Moves
This evening I successfully moved a second set of services from service provider IP space to BGP IP space. The first phase of this project began over a year ago – I turned up AS62758 in early December 2013 prior to the migration of a Learning Management System. With this second phase now complete, most externally offered services are now running on BGP IP addresses. I have two more remaining phases, to move the access NAT network, and to move a Student Information System. These remaining two phases will be happening over the next two weekends.
- Reduced TTL values on affected records a week before the change.
- Pre-configured new firewall with new IP addresses, 1:1 NATs, and allow/deny rules.
- Pre-configured PTR records.
- Pre-modified SPF record to add new IP range.
- Tested several of the port forwards with a simple Debian VM running an nginx server to display a success page.
- Changed affected VM’s network from old to new network.
- Made several cabling changes/additions.
All testing was successful, which makes sense, as no changes needed to be made on the systems themselves, just firewall, and physical/virtual cabling changes.
