Hy am very new in Mikrotik technology and I want to build a Link at 8 Km between 2 sites.I have succedeed in building the Link I can ping the Wireless Interfaces but I don’t know how to ping the ethernet interfaces.I must tell that the Wireless interfaces are connected by the Nstream Protocol.Please help me because I really don’t know how to connect the 2 sites P.S. :If you can post a reply for a N00B person it would be great
there are 2 possibilities open for you
first is routing and use of routed networks. you can find that information in manual, like - simple routing (static routing) or OSPF
second possibility is to follow this wiki how-to
http://wiki.mikrotik.com/wiki/Transparently_Bridge_two_Networks
and build ptp link and transparently bridge together 2 places.
EDIT:
if you choose routed networking and to learn more about features RouterOS is providing then this part of manual is very essential for you
http://www.mikrotik.com/testdocs/ros/2.9/#IP%20Addressing%20and%20Routing
since you already created link and it is working, i think that job should be really easy for you.
