Remove static routes for second Connection.

RouterOS Scripting
1

I have 2x ADSL connections on my Mikrotik. One for Local traffic, the other for international traffic…

Although I did create a script to route local traffic, I want to be able to delete these (static) routes all when needed…

Possible to delete all static routes?

You can use the Mangles facility inside your Firewall to choose who can use each DSL connection in your local network.
