So, I have a machine on my network, which should be only connecting to the internet through a VPN. I needed to tell my RouterOS box to block all access, except to this said IP address… The following should do the trick… YMMV
this will drop any packets from the srcaddress (IP address) that are not for the destination dstaddress (IP address). in my case, dstaddress is the VPN server I want to connect to. So, in theory, all packets should just go through the VPN and not leak out into the rest of the network… again, still testing this so be careful!
