Hi!
I would like to ask if Mikrotik RouterOS is able in some way monitor port 80 (http).
Config is the following:
Router has a public IP. Has a vpn to our central office.
VPN and internet from behind the local router didn't worked.
We were able to connect to the router trough the public IP and check the config. It was OK.
Then figured out if the ping works from the router and the local subnet to the internet it should be a blocked port problem.
Checked with the local ISP and the had blocked almost all the outgoing ports.
So has the ROS some tool to monitor if a port is open?!
Thank you for the reply!
Best regards

Run telnet to port 80 (it is working, when any program is listening on this port),
when port is open you get reply,
Port 80 is closed,
when port is open you get reply,

Trying 1.1.1.1...

Tera Term Pro is a telnet client with a built-in scripting language. It can also be programmed to change settings in MikroTik Routers if certain conditions are met.
