Help needed: forward traffic from one port to other 3

Hi there,

I’m struggling with setting up my device. Need help.

Here is what I’m trying to achieve:

I have 5 physical interfaces with the following IP addresses:

Physical ether1 (management): 10.2.10.10/16
Physical ether2 (video encoder): 10.2.100.1/16
Physical ether3 (net 1): 10.2.3.1/16
Physical ether4 (net 2): 10.2.4.1/16
Physical ether5 (net 3): 10.2.5.1/16

Physical ether1 will be the router’s management port. No problem with that.
Physical ether2 - video encoder with IP 10.2.100.2 (video encoder can do up to 4 streams but have only one physical interface), which should be streaming to:
Physical ether3: to IP 10.2.2.11 UDP 5000.
Physical ether4: to IP 10.2.2.90 UDP 2314.
Physical ether5: to IP 224.23.0.113 UDP 1234.

Interfaces 3, 4, and 5 should be isolated networks. So no communication between those.

With Torch, I can see the streams going on interface ether2, but any attempt to route the streams to desired physical interfaces resulted in no success.

Please, guide me in the correct direction. Thank you.

Well its plain to see,based on the provided info, you should repeat what you did for ether2, for ether3 and ether4! :slight_smile:

Look again to the /16 !

Everything in the range 10.2.0.0 till 10.2.255.254 , it is all one and the same subnet here, except the 224 (broadcast?) address.
AFAIK no routing will be done between interfaces of the same subnet, they are supposed to be bridged here.
The /16 probably is or has to be /24, and the ethernets not connected to a bridge.

Well, I did things I found on the forum like 1 LAN (Encoder) to 2 WAN (assuming the WAN are isolated ports), and everything ChatGPT suggested.
As I’m new to MikroTik, I tried different configs and reverted so many times, that now I can not tell exactly what I deed…

Now, again, I have a clean config.

No, I do not need a bridge. The interfaces should have designated IP addresses and isolation. The 224 one is a multicast stream. I need to redirect the specific stream from port 2 to the other physical ports.

No, I do not need a bridge. The interfaces should have designated IP addresses and isolation.

Routing will not work if all interfaces are the same /16 subnet. What is the case in your config: /16 means that only 10.2 defines the network/subnet (netmask 255.255.0.0) , the rest is per host/device)
