Bridge & ARP question

RouterOS General
1

Hi all,
If I’ve got a RB with “PUBLIC” (WiFi) and “LAN” Interface…
Let’s say the Public IP is 10.0.0.1/24 and I want to bridge the internal LAN to be accesable as if they are all directly connected to the 10.0.0.0/24 network.

E.G. on the LAN interface I have PC’s with IPs 10.0.0.10 & 10.0.0.11
Will a PC on the Public network with IP 10.0.0.2 be able to ping 10.0.0.10, i.e. will the RB respond with ARP on all IPs connected to it’s internal interface just by bridging the PUBLIC & LAN interfaces?

Thanks
Ekkas

if you bridge your public and local interface, btw, to bridge you have to have wifi atleast in ap-bridge mode

I just want to simulate a simple wifi bridge like a senao where I can have ips behind it that is on the same network as the wirless client side…
Any advice?

janisk already said that you need bridge interface and wlan1 and ether1 added as ports on it. if wlan1 is not ap-bridge, you probably need also wds features on that interface. it’s one more (very important) question: is it possible to use wds… what’s the interface on the other side. is there wds features too.

Thanks, yes other side is also a MT unit. But for this one client, I just made another subnet to get them going, should be alright. Had to change IPs and so on but it was urgent so had to get it working…

Thanks anyway

let’s say the two units are RB’s and we bridged the wlan + ether .. what about the wlan on each side ? ap-bridge or station or … ?

[ap-bridge + wds static] both sides. each router bridge with ether1, wlan1 and wds1 as ports.
