I currently have my internet connection from a local provider. It is plugged into ether1 on my routerboard. I now have the opportunity to use a friends connection. It is double the download speed and quadruple the upload. I am thinking of purchasing a couple UBNT NanoBridge M5-22. to link to him about 8 miles away. I wish to only use his connection for voip and torrent usage and all other traffic on my system. I know i have a lot more reading to do but I would like to get the equipment and ordered and installed on our towers asap. Is it easy to set up such a network and is the nanobridge a good choice. His router is also a mikrotik and I am allowed full access. In exchange all I have to do is maintain his network.
Thanks
Lyle
have you tried using some pcc? I believe you can
/ip firewall mangle
add action=mark-routing chain=prerouting comment="Voip" in-interface=ether1 \
new-routing-mark=voip passthrough=no protocol=tcp src-port=1234
/ip firewall nat
add action=dst-nat chain=dstnat comment="voip" disabled=yes dst-port=1234 \
in-interface=ether5 protocol=tcp to-addresses=[b]voip phone IP[/b]
then
route it to your friends IP
/ip route add comment="Route Voip Traffic" distance=1 dst-address=[b]friends IP[/b] gateway=\
ether5 routing-mark=voip
I may of forgotten something…Hope that helps 
That seems simple enough. I will do some more reading and order my new equipment. Thanks for pointing me in the right direction.
