I’m trying to do some security I have a router hooked up for testing with one computer on it and I’m adding the rules to that router. This is a kind of big network with about 15 routers. There’s a core router that it keeps adding to the block list when I add the firewalls from these to pages.
Make life easier for yourself and rather just have a default deny rule on the input chain.
The only explicitly allow access on the input chain for yourself and/or your network.
Also move your services (ssh, winbox, etc) off the default ports. For example run ssh on port 22222.
