[labnetwork] Static IP Addresses needed for hardware interlocks

Thu Apr 8 11:24:24 EDT 2021

Hi Julia,

I want to piggyback on what some of the others have said.

UCSD uses FOM and we have blocked many of our relay controls from the
outside internet by placing them on special subnets/VLANs. Inside each
subnet/VLAN, we can set up rules about what the devices can see outside of
the subnet/VLAN. I think this is very similar to what Michael and Ryan said
above. It should be possible within FOM, but getting IT to work with you is
another story.

Please let me know if I can be of further assistance.

John
