Firewall rules inbound/outbound + NAT

[AntoineBAK]

Hello

I would like to understand why there are firewall rules inbound and outbound in two separate menus as traditional firewall, there is only one menu with inbound and outbound connections ?

can you explain what do we mean on Meraki by inbound and outbound ?

Other topic : What about the priority given to the different NAT configuration

If we have port forwarding and 1:1 NAT both configured for example, which one has a higher priority ?

thanks !

There is all information that you need:


https://documentation.meraki.com/MX/Firewall_and_Traffic_Shaping/MX_Firewall_Settings

https://documentation.meraki.com/MX/NAT_and_Port_Forwarding/Blocking_Inbound_Traffic_on_MX_Security_...

If you check the documentation you will notice that port forwarding and 1:1 NAT have differences.

While port forwarding uses the IP configured on the MX's WAN, in 1:1 NAT you can define another public IP within the block that your ISP provided, obviously if it is not a /30.

So there is no priority.
