i have asrock fatalit1y pro gen3 with 2 lan rj45s
which 1 do i use for only 1 conection please
routers/switches with multiple LAN slots for RJ45 make equal use of all slots - -
you can use any, some, or all without concern that there might be differences in the usage.
The WAN slot (on routers) or sometimes the UP LINK on a switch does matter;
they both go to the TCP Source that is to be share via the LAN.
but these fuk@#$%^& questions r waiting so much time and patience
