udp

Hi.

I’ve played around with home networks successfully, but I’m new to routeros and more detailed networking configurations. My background is application development, not network administration.

I’m using an RB751U-2nHD running RouterOS 5.16.

I have a simple udp server and client that I’m using to test network configurations. When I run this on my work or home network it works just fine, but when I tie the client and server computers into my MikroTik router there is no communication between the 2 pcs. I have done this hard wired and wirelessly, with the same results. Both computers are correctly getting their DHCP addresses from the router, FWIW, so I know they see the router ok.

I have done some searching in the docs and on google, but I have yet to find a direct answer to my issue. I can’t believe I haven’t found the answer yet so I must be overlooking something obvious.

I would greatly appreciate any advice/pointers to help me get past this. If this has been posted before then please just post the link to the answer. Thanks in advance.

Post your config (output from /export compact) with a note of which ports the relevant devices are attached to.

Thanks for responding. This will probably reveal what a noob I am. I'm seeing some errors near the bottom of this output. During the output of this both computers were connected wirelessly.

Hi.

Any ideas?

Someone else (offline from here) suggested bridging all interfaces together. For lack of a better idea I’m looking into that now.

Thanks.
