This might sound like a stupid question to ask but I guess I will have to take that chance!

I’m hoping that someone can answer these two questions.

For security, can routerboard be set to only allow certain mac address into it, on port 5678.

Is there a way all data that goes threw port 5678 can be encrypted?

Thanks

5678? is it Neighbour Discovery?.. why do you need it to be encrypted?
