you have/
1- A broadband pppoe mikrotik server
2- tp link router 1
3- tp link router 2
the broadband pppoe mikrotik server gives a username and password to the tp link router 1 to aceess the internet .so the first router access the internet via( username + password broadband account connection )
now,we brings the second tp link router 2 and connect it with the first tp link router .so the second tp link router will get the internet via DHCP DYNAMIC connection from the first tp link router 1
the questin is =
how can i get any information about the second router (not the first ) by mikrotik server ? wich tool ? which way in mikrotik server to perfom this idea?
When traffic gets routed, source MAC address gets lost or replaced by router’s MAC address (the former happens in true point-to-point technologies, such as serial line or L3 VPN), hence packet looses fingerprint of the original sender. When there’s SRC-NAT involved, src-port pattern gets garbled, so you can’t deduct remote device’s personallity based on open ports pattern. Combine both and you loose any insight of what’s behind that black box.
if you have to discover remote devices on router 2, make it a bridge, instead of a router. turn of DHCP on the TP Llink, connect a LAN port of router 2 to a LAN port of router 1.
this is the only way to do it if you want to monitor inside of Router 2.
same apply to Router 1, it needs to be a bridge too so the Mikrotik can see what’s behind it.
