Setting up a secondary router to allow connection to only one host on different subnet

July 18, 2013 2:20:16 AM

Hi there folks,

Basicly where i need help with is this:
I have a secondary router with wireless. I want to set that router up on a different subnet with mac filter and not communicate with the main router, not giving access on all pc's and the internet, but do on only one ip on that main subnet.

I've tried allot but as something should work i'm not getting results.

e.g. this did not work at all ROUTE ADD MASK nor

Please be of help if you have the time

Kind regards
