Print Page - Firewall Rule to Block all Inbound Traffic

Title: Firewall Rule to Block all Inbound Traffic
Post by: Smack2k on May 31, 2019, 01:12:26 PM

I realize this may be a dumb question, but I am new to the OpnSense Interface, so I want to make sure I set it up right...

To setup a Firewall rule that blocks all Inbound Traffic to the Firewall (Traffic trying to get in from the Internet) what would be the proper setup of the rule? I know the rule would be set on the WAN Port, but not 100% sure of the Interface and what goes where...

Interface - WAN
TCP/IP - IPv4+IPv6
Protocol - Any
Source / Invert - ?
Source - Any?
Destination / Invert - ?
Destination - Any?
Destination Port Range - from Any to Any

Thanks ahead of time for the assistance...again, I know this should be simple, but I want to make sure I am seeing it properly!

No need to set up a rule - inbound traffic is dropped by default.

Shields Up! will confirm this: https://www.grc.com/x/ne.dll?bh0bkyd2
