[lime-users] First time user - using my own router

by Jason Gauthier

Greetings, I've been looking for a mesh network for my home to ease the trouble with flakey and various APs from different vendors. One issue I continually run into when shopping for a mesh setup is that many of the commercial ones want to replace your router, take over DHCP, etc. With LibreMesh is it possible to continue using my own router? I have a Cisco ASA that I am somewhat partial to and I don't want to stop using it. I couldn't find anything (obvious) in the docs on how if this scenario was possible. Thanks, Jason

[lime-users] port forwarding / static ip / dmz in lime?

by bruno vianna

I want to host a public server in my local mesh, so I need to forward ports and assign static ips. What is the best way to do it in lime? If I use openwrt uci on the gateway, will it replicate to other nodes? What about DMZ, does it make sense in lime?
