HI,

I've a RV042G router and SG200-26 swithch

port 1 on vlan 1 is management 1UP,2T

port 2-26 on vlan 2 2UP

normally it cannot communicate to port 1 unless i plug the cable directly to port 1 to manage it

here is the question, im using VPN to connect back to office, but how can i manage the switch through vpn
