I have 2 servers, 192.168.1.1 and 192.168.2.1. I want to relay any broadcast traffic (192.168.2.255) through 192.168.2.1 to 192.168.1.1.
Here's what I'm doing to relay port 137 traffic, and it seems to work fine.
echo ncat.exe 192.168.1.1 1337 > relay.bat ncat.exe -l -p 137 -e relay.bat
nc -lnvp 192.168.1.1 1337
I can only find how to forward ports with ncat. I can't bind to 192.168.2.255 to listen of course. I hope that makes sense what I'm trying to do.
