I am pulling my hairs out on this one.. I am trying to open port 28967 from the modem towards my Linux file server. Please see my network diagram below. I tried including all that might be relevant.
I can do telnet 192.168.2.114 28967 from my Windows laptop and it gives me a blank screen immediately, which indicates to me that the firewall on my Linux fs is OK.
Next I want to configure my router 192.168.2.1 to forward port 28967 to 192.168.2.114. Please see the configuration below. I am stuck here. Currently I am forwarding from lan to lan to make it easy for me to test it from the couch. Later, when this works, I will be forwarding wan to lan. Now, when I telnet 192.168.2.1 28967 I get a connection time out and this is where I'm struggling to find out why.
