I have mikrotik routeros installed on an x86 system.
I have 2 LANs.
LAN A. -192.168.30.0/24 for PPPoE clients
LAN B. -192.168.1.0/24 for my proxy server and Elastix server
I could access my elastix web gui and could place/receive calls when I am on LAN B.
However I could not do the same when I am on LAN A.
