Hello all
I’m pretty new to the world of Mikrotik and RouterOS, and I would appreciate your help on this.
On a wireless network i’ve build up for my local community, I have 2 RB 750G.
One is at the internet source, with two ports used, one at the wan side, and one at wlan side.
I’ve already setup this one as a bridge, remotely, but it was before I finished the network, I was alone on it, and by trying, I’ve done it without problems.
I had only 2 active interfaces, so by giving different IPs to each interface, I finally found which one was attached to the wan and which was attached to the backhaul antenna. I got access back to it, and put everything in the bridge.
I’d like now to setup the second RB as a bridge. Up to now it works only as a switch, configured as defaut, with port 2 as master and port 3-5 as slaves. I know that port 1 and 5 are unused, as I can see it with winbox (those ones aren’t synchronised at 100mbits FD)
Ports 2-3-4 are connected to :
- my BH antenna
- one 120 sector
- one 60 sector
But I don’t know which one to what port exactly
What I’d like to do is to put these ports in the bridge. The problem is that it is now connected to Internet and used by my neighbors.
do you know a way to do this silently, transparently, with minimal downtime for users ?
What i thought to do was to give each port an IP address, then when I would put the port out of the bridge, if it is the port I’m connected to, i could use this IP address to connect back to the RB and continue my setup. Shouldn’t take more than 5 minutes.
I first choose to give IPs in the same subnet (192.168.71.241/24 to 192.168.71.245) to each port. But not all IPs answer to my pings.
When I read the wiki manual, it says
Two IP addresses from the same network assigned to routers different interfaces are not valid unless VRF is used
So I believe it explains why only some of those IPs set on switch’s ports answer my ping,and some others don’t. Only 2 on 5. Strangely one of the IP that doesn’t answer my ping is the IP i used to connect to this routerboard. It works with winbox or telnet, but not for ping.
Anyway, I can count on this, I want to be sure to connect back to the RB when the ports are get out of the switch configuration.
i don’t want to use VRF for this. I read farther that
For example, the combination of IP address 10.0.0.1/24 on the ether1 interface and IP address 10.0.0.132/24 on the ether2 interface is invalid, because both addresses belong to the same network 10.0.0.0/24. Use addresses from different networks on different interfaces, or enable > proxy-arp > on ether1 or ether2.
Should I set proxy-arp on all ports ? just one ? which one ?
Would this solve my ping problem ? and enable me to connect to any of the IPs, especially to the port my AP is connected to ?
Otherwise i think I have another solution, that is simply to give 5 IPs belonging to 5 different subnets. I’ll give 5 others to my own antenna, and maybe will it be OK ?
Is it the way to go to do that ? What do you think of it ?
For the rest, the bridge interface is already created but has no ports, it has a public IP, users/password are set, masquerade and DHCP deleted on port 1. I just need to put these 3 ports in the bridge
How would you do that ?

Fred
), and you’re right, I should have done a network map. That’s not easy to show the picture only by writing about it.
