So I have been cleaning up the networking cables of my homelab. Starting with my server, I have a cable that is terminated with a keystone jack on one end and a field term connector on the other end. With my cable tester, it’s fine; and when I plug it into the server, I get lights. However, I don’t get IP. This has me stumped. The old cable with regular RJ45 terminations works fine. What gives?
Orange-white, orange, green-white, blue, blue-white, green, brown-white, brown. 
For these terminations, they are labeled for T568B (and T568A). Also I found an ethernet cable tester when I went to Micro Center a few weeks ago and if the cables are swapped, it shows that. If there is a bad connection on the cable, it also shows that. This cable is a good cable.
I’m mostly wondering if it has something to do with the field term connector or something.
An rj45 cable on both ends works (and gets an IP)
test the other cable (keystone) to another system which you know will get an IP.
The keystone connection might be bad.
I can try another system. That’s a good test.
However, the way I am testing it now is that I made my short cable that I intended to go from the patch panel to my Netgate box. I tested it with my cable tester and verified that it’s a good cable. Then I plugged it into the keystone port, and hooked the other end to one end of the cable tester. Finally I plugged in the field term connector to the other end of the cable tester and tested it.
log time ago I had a cable that the cable tester showed good.
but the cable was not wired either as A or B so it would not get an ip.

Just got a chance to try this out on another system, the system I am currently typing this on as a matter of fact with said cable connected, and it works.
So I reconnected it back to the server, patch panel, and Netgate appliance; and everything works now. 
On a side note, it’s interesting to me how running an iPerf test between my homelab server to my desktop is faster than running the same test between PFSense and my desktop. Any ideas why that is the case?
my network is 1Gbps.
I tried iperf on pfsense, I get 941 Mbps between iperf and a server.
Tried iperf3 between servers, same.
Hmm. I have 2.5GbE for everything, so I get about the same result as you between PFSense and my desktop. But through the firewall, I get about 2Gbps.
