Default Gateway of Bridge

RouterOS Beginner Basics
1

Ok this is what I am trying to do.

I have one uplink port (eth1) and two additional ethernet ports (eth2, eth3) and wirelese (wlan1).
I need to have on port eth3 direct wan network for TV setup box. I have created a bridge for that and it works.
Then I wont wlan1 and eth2 to be in the same network and that they get ip from dhcp pool and access to the internet via eth1. Now I created a second bridge and I put dhcp pool on that bridge and when I connect I get IP address but no access to the internet.

Is my concept wrong or I need to configure something else?

Did you setup:

  1. src nat / Masquerade on ether1
  2. Default gateway for clients pointing to Bridge IP in DHCP
  3. DNS Server IP’s for clients in DHCP

I added src nat / Masquerade on ether1 it works if I do not add eth1 to bridge, a soon as I add eth1 to bridge the maquerade rule gives this error:
in/out-interface matcher not possible when interface (ether1) is slave - use master instead (eth1_pass_to_eth3)

According to your OP, ether1 is your WAN/Internet port, why will you want to add ether1 to Bridge with ether2/wlan?

You may bridge some LAN segment ports for your needs. Don’t bridge ether1 port, cause it’s terminating interface for your ISP network.

Yes eth1 is wan port, I need eth2 to have direct wan network (TV-setup box gets IP from ISP you can not use your own DHCP).
Currently I have between wan (modem) and router additional switch and tv setup box is connected to switch. I wanted to eliminate the switch this is why I bridge the wan network (eth1) with eth2.

Then put masquerade rule on bridge interface that has members eth1 & 2
