what line I need to disable and what one to add if I want to change the three ADSL modems to bridge mode so Mikrotik router get the public IP from ISP.

Re: change multi WAN Mikrotik router setting if modems bridg

You set the modem to bridge mode, set up PPPoE clients on the three interfaces (http://wiki.mikrotik.com/wiki/Manual:In ... PoE_Client) and replace the references to the WAN interfaces and WAN ranges with the new information. You'd also replace the gateways of the routes with the interface names (for point to point links like PPPoE connections you can refer to interfaces instead of IPs). I can't be more specific because you choose the WAN interface names, and we can't possible know the IP address ranges they use to assign addresses.

after creating pppoe clients for each wan port, should I change all the interfaces and gateways setting it as the fallowing
Code: Select all
/ip firewall address-list

/ip dns set allow-remote-requests=no cache-max-ttl=1w cache-size=2048KiB max-udp-packet-size=512
I kept the IPs in the top of the code to enter the modem pages. I need to change to bridge because I have around 30 user online in the same time and they have many connections. I thing the modems doesn't handle many connections at the same time

after the change, it seems that I can no access the modem pages. what should I do?

Note: when I connect to the modem directly I can acess the modem page ( for example modem 1 : 192.168.9.168)

I have added nat rule for wan1 , wan 2 and wan 3 and now I can acess the modems but will this effect the load balancing (Is this OK?)
