ping from outside my 3 different gateways..

RouterOS General
1

hello all,

i have a local network, connected to a Mikrotik router, which has 3 different connections to the internet (3 ADSL modems).
i mangle all the devices from the localnet i want, to route through the specific gateway (ADSL modem) i want..
i also have a main mark, which is used as a “default” gateway for unmangled devices via ADSL-1.

when i try to ping those three different outside addresses from the internet, I can only ping the “default” address (ADSL-1).
my modems are setup to forward all packets to Mikrotik router.

so, is there any way to solve this problem, since i have an external monitor server, to notify me if an ADSL modem is down..


Regards,

George
