Hi I am new to Mikrotik & would like help with the following situation. I have a client who wants to install wireless for voice services. I have worked with enterprise wireless products that have the ability to allow clients to roam across subnets securely & have fast handoffs as well as keeping the client IP whilst roaming. Does Mikrotik have the ability to do this, if so where can I find help with the configuration of the router boards? Thanks in advance Sweeper
you probably could implement pseudo-mobile-IP in MT. Usually these things are in the wiki (wiki.mikrotik.com), but there’s no such thing as a step-by-step guide on how to implement it (yet!).
You would need to set up EoIP tunnels between your off-subnet APs and a router placed on the main subnet. This way the wireless clients all appear to be on one subnet.
You can read up more on EoIP tunnels at http://www.mikrotik.com/testdocs/ros/3.0/vpn/eoip.php
Finally, keep in mind that MT’s AP mode doesn’t work too well with VoIP mode. Handovers are slow as there is no Inter-AP communication, so if you’re using WPA the client (phone) will have to go through the whole handshake each time it changes AP. Also, the lack of antenna diversity on the 11a/b/g modes can be a killer for voice.
