NAT Migration FAQ

What is NAT and how is it affecting the wired network?

NAT, or Network Address Translation, is a technology widely utilized in home Internet routers and large enterprises. It eases the burden on computers requiring public IP addresses by using a set of public IPs to route traffic through a network to private IP addresses. This enhances security and optimizes IP address utilization in wired networks.

Why is the BUMC wired network changing?

The changes to the BUMC wired network are driven by a commitment to enhancing overall security. The primary goal is to fortify the network against potential cybersecurity threats. By implementing these changes, BUMC aims to stay ahead of evolving security challenges, ensuring a safer and more resilient network environment for all users.

Is this change only affecting BUMC buildings?

This project initially targets BUMC buildings, but the technology is already in use by new buildings across campuses, including the Center for Computing & Data Sciences. Its goal is to streamline and preserve the university’s public IP space, eliminating the need for separate IP allocations for BUMC.

How will the network address change impact me?

The network address changes are specifically designed to bolster security measures. While the intention is to increase overall protection, users who currently connect to external vendors or campus computers using specific IP addresses may be affected. We recommend reviewing the provided guidelines to understand the potential impacts and take necessary steps to adapt to the changes.

Will I need to do anything to adapt to the network changes?

Yes, users may need to make adjustments in their connection methods. It is recommended to switch from using IP addresses to using the computer’s hostname, such as BUMC-PC######.ad.bu.edu. Detailed instructions on how to make this transition are available on our website. We encourage all users to review and follow the provided guidelines to ensure a smooth adaptation to the network changes.

What if I experience issues after the network address change?

In the event of any issues following the network address change, please reach out to our support team at bumchelp@bu.edu for further assistance.

Can I still connect to computers on campus using an IP address?

Yes, but you will need to update to the new IP address after these changes. To avoid issues, you must use the VPN and we recommend using the computer’s hostname.

Regarding my reserved/static IP provided to a third party for internet system access, what IP details do I need to give them after the update?

If you had a reserved address before the change, you should still have one after. If not, request a new one by opening a ticket. In either case, the third party will observe an IP address within a small subnet range, and you should share that range with them. For assistance, contact bumchelp@bu.edu.

For my reserved/static IP granted access through firewalls at CRC Datacenter, what IP information will I need to provide after the change?

If you had a reserved address before the change, the IP will change but it will still be a reservation, just a new IP. The third party will see an IP address within a specific subnet range, and it’s important to provide them with this information. If needed, reach out to bumchelp@bu.edu.
