MikroTik

I have mikrotik at one of my towers for a test run. I can issue public and natted private addresses through the pppoe, works good! However I cannot admin my wireless equipment behind the mikrotik. Is there a way to pass the 192.168.100.0/24 subnet through the router (just like a bridge) as well as have the private addresses natted and the public addresses going right through?

then when you need to access anything on that side you just conect to the vpn this way you can keep it secure too
