Hi Everyone, I just reset my RB750Gr3 and on the first page : 192.168.88.1/webfig/ I can see Bridge All LAN Ports what it is meaning ?

By default ports cannot communicate between them ? or it bridge port one to the rest ?

I couldn't find the info on https://wiki.mikrotik.com/wiki/Manual:TOC or on the forum....

It makes the wired LAN ports act like a single switch, including the wireless LAN ports. So it makes it work the way you would expect if you came from a consumer router.

OK, but by default Port 2 to 5 are switched together, but without wireless and port 1 (aka WAN) right ?



port 3,4,5 are slave of Port 2 and therefore this is switched correct ?

Well, your question is about QuickSet... The usual advice from any experienced community member is "don't use QuickSet, ever". And I'd rather second that advice. So... Do not expect anyone to answer your question, unless someone from the actual Mikrotik staff looks here in the topic. Simply because nobody knows/cares.

Hi.

hEX has 5 ethernet ports, marked on the outside as "Internet/2/3/4/5".
Default config follows this - ether1 is configured as separate interface that is meant for WAN/Internet access, ether2-5 are a bridge for LAN devices (so each LAN device can talk to each other).

Enabling the "bridge all ports" means "all ports are LAN", in basic terms, so port1 is no longer special.
You would use this if you want to use the hEX as a dumb switch (because you already have the hardware) or use something slightly more complex/advanced for WAN/internet access (PPPoE, tunneling, VPN, LTE modem in USB port, etc).

That said, start with upgrading RouterOS, because master-port is an outdated concept so you probably are running old version.
