In the end we got it working with this configuration:

Roborio:
static ip: 10.16.58.2
subnet: 255.255.255.0
gateway: 10.16.58.1
plugged into the AF port of the radio

Driver station laptop:
static ip: 10.16.58.5
subnet: 255.0.0.0
gateway: 10.16.58.1

Vision processing tablet on robot plugged into ethernet switch:
static ip: 10.16.58.6
subnet: 255.255.255.0
gateway: 10.16.58.1

another open port of the Ethernet switch is plugged into the remaining port on the radio.

doing this we can use it on field and off field and always communicate to them with the desired ip addresses.
the tablet talks to the roborio on port 5801 and the driver station on port 5802
