Here's my use case :
I have 2 independent networks & 3 servers. Server 1 & 2 are connected on Network 1 (172.24.xx.xxx) while Servers 2 & 3 are connected via network 2 (locally : 192.168.1.x).
Now, Server 1 has a NTP server configured. So, I configured a NTP client on Server 2. Everything works fine till now.
But, now I also need to synchronize the Server 3 (on local network). So, can I install both NTP server & client on Server 2, such that NTP client daemon syncs with Server 1 & NTP server daemon connects with Server 3.
