Trying to understand default configuration of hAP2

RouterOS Beginner Basics

Hi,
As a newbie to these routerboards I am trying to understand the default configuration settings for ‘Home AP’.

I can see a bridge has been created for ether ports 2 - 5, with ether 1 being the WAN port. My question is which part of the configuration ‘connects’ the WAN side to this specific bridge?

Thanks.

A few aspects:

  • ether1 is not part of bridge meaning that devices connected to bridged interfaces and devices connected to ether1 can not communicate directly, they have to use router as gateway
  • ether1 receives specific configuration depending on ISP requirements (either DHCP client or PPPoE client or …)
  • firewall rules treat WAN interface differently - blocks incoming connections, firewall performs NAT for outgoing connections and port forwarding for select incoming connections (if configured).
    For this part to function correctly it is important to keep membership of interface lists current and correct. And default config makes ether1 member of WAN interface list. If PPPoE is used, also corresponding interface is added to WAN interface list.

Hi,

take a look at IP > Routes. There is defined which “way” your device should go for your LAN(192.168.88.0) or WAN (0.0.0.0)

If ports are not member of a bridge, then packets need to go trough the routing process.
