Make one of the ZeroTier nodes as the intermediate device which routes traffic from/to ZT (enable IP forwarding).
You'd need to add the appropriate route for your internal network to go via the intermediate node in ZeroTier console, and add a static route on your main router for all ZeroTier traffic to go via that internediate ZT node.
Thank you for your reply @varkey . actually i am understanding the concept that you are saying but iam new to ZT and BSNL-FTTH last week only i got my connection.. so iam having no idea how to implement it practically. can you please say it elaborately
yes i planeed to use a rashberry pi for this job ... and i did'nt prefer to use another router.. because iam in need of using rashberry pi
and i having one dout @varkey as you said in early posts we can use bridge mode and bind LAN 2 port for that voice configiration
what i like to know is can we create another AP(SSID_2) in the ONU and is it possible to bind that second AP with that
if i did like that it will work or not? and is that supports SIP Forking..?
