In setting up a new RB750 I noticed that its default accept established and related connection input rules have the WAN port listed as the in interface, but the router at demo.mt.lv does not specify an interface.
None of my basic configurations have ever specified the WAN interface, any idea why the 750 does?
Any advantages?
depends if you trust your local network. if you don’t want any limitations on the internal network, specify only the WAN interface for your blocking rules.
