PMA Firewall

Why is this being done:

A firewall has been installed to protect the PMA network from the rest of the campus and the world. The goal is to decrease the number of exposed vulnerabilities on the PMA network. This increased security will cut down on the number of ISO quarantines about services listening on the network and prevent devices from being blocked on the network. Over the next five years, we will work with building tenants to move them to a new scalable network to align the building with the rest of campus centralization efforts.

What departments does this effect:

Physics
Fusion
Math
Astronomy

What type of connections does this affect:

Wired only, wireless is not changing
Devices on public networks only (private will not be affected)
1. Public IP addresses begin with 128, 146, or 129.
2. Private IP addresses that start with 172 or 10 are not affected

What will still work (please see graphic below):

All traffic within one department
All traffic from any computer connected to VPN
All outgoing connections from the computer inside PMA except when connecting to a different department in PMA
If you can perform a task while on Wi-Fi you will be able to perform the same task while on hardwire except when connecting to a different department in PMA
Connections to instrument and printer networks
Any whitelisted services (Complete this form to request a service to be whitelisted: https://utexas.qualtrics.com/jfe/form/SV_6Rplgi8pWRUTz9j )

What will no longer work after all the rules are applied (please see graphic below):

Traffic between departments: Physics, Fusion, Math, Astronomy
Incoming traffic initiated from TACC (it is recommended to initiate the connection from the computer in PMA not from TACC)
Incoming traffic from devices on Wi-Fi

When will this be done:

Due to the unknowns surrounding the COVID-19 pandemic, we aren't able to provide a full schedule. This graphic will be updated as dates are determined.
