LTE + Ether1 gateway

Fri Jun 17, 2022 2:19 am

Hi all! I have two ISP (one on Ether1 with DHCP on 192.168.8.1) and second on Lte ( DHCP 192.168.8.2)

I want to route all traffic from eth2/eth3/eth4 to ISP1, and all traffic from WI-FI to ISP2

I read some articles about mangle but can't figure out how to use it in my case. Do I need to create separate bridge for Wlan1 and Wlan2? Thanks!

First seperate the networks of the two ISPs, as you mention both are on the network 192.168.8.0...
The simplest thing you can do is routing rules... https://help.mikrotik.com/docs/pages/vi ... d=59965508

Could you help? Can't find where is my mistake. All traffic still going to 192.168.8.1 gateway. But I want Wlan2/Wlan1 to 192.168.9.1

The simplest thing you could do is create a second bridge for wlan1 and wlan2, assign an IP address to that bridge ( different from the one used now ), create a DHCP server on that bridge, and then on policy routing rules for that subnet use as table your ISP2 table.
