Recently,
I configured a RB1100Ahx2 to work and provide multiple network on different interfaces. Ether1 & 2 are bridged in bridge1 and work in a 10.0.0.0/19 network with hotspot enabled. Ether6,7 & 8 are bridged in bridge2 and work in a 192.168.1.0/24 network. Ether9 is configured in 192.168.88.0/24 network (no bridge). Ether10 is the WAN interface with PPoE client running. All interfaces are confiured as proxy-arp.
Internet access works flawlessly and IP distribution with DHCP servers running on each network.
Now my issue is that on bridge2 and on ether6 I am connecting a switch where other devices on the switch are connected with static ip addresses from 192.168.5.0/24 and 192.168.6.0/24 due to application server configurations. When the lan cable is connected on the mikrotik a lot of ip conflicts occurs, on the computer which has different IP configurations on its IPv4 configurations in windows.
When we are using the ISP’s router with the default settings on 192.168.1.0/24 network no conflicts are happening.
(I allow forward traffic on all subnets and srcnat masquarade also)
Any clue on what is going on ?
