This guide will help DIY Linux users who wish to setup more than one provider on their network. It is assumed that the first provider, whether it’s an XA miner or a DIY Windows/Linux/Docker/NAS provider, is running on the default ports of 4281-4285 (note only 4282 and 4283 need to be forwarded from spd 1.6.2 onwards). A second provider cannot be run on the same default ports as the port forwarding on your router can only forward port 4282 & 4283 to a single internal IP address. Therefore when setting up multiple providers behind the same external public IP address, the ports need to be changed on the second (and subsequent) provider to non-default ones.
