For VHF, the RMS Packet, EA5HVK VARA FM, and UZ7HO Soundmodem settings are:
Note that you will need to specify unique port numbers for Soundmodem and the two copies of VARA FM. If you leave the port numbers set to the defaults you’ll get port conflicts.
For UHF, a second copy of RMS Packet and a second copy of VARA FM are started. After you’ve installed RMS Packet and VARA FM, make copies of the folders for each before you start configuration. That way you start with a clean configuration for both the VHF and UHF sides.
I use RMS Relay so the Gateway will still be usable for local VHF/UHF traffic if the Internet connection fails.
A little wrinkle here: if your gateway is connected to an AREDN mesh network (as is my other gateway, W4UVA-10) then your gateway computer will need an additional Ethernet port to connect to the mesh network, and you will want to select the mesh IP address at “IP address to receive connections” on the “Site Properties” panel. (See https://www.cvadn.net/winlink-mesh/ for client configuration details.)
I use Startup Delayer (https://www.r2.com.au/page/products/show/startup-delayer/) to make sure things start in the right order: Soundmodem, RMS Relay, RMS Packet (VHF), RMS Packet (UHF). The two instances of RMS Packet are configured to automatically start the two VARA FM instances.
