I am setting my 2 antminers at a location I lease, I don't have control over the building's internet or router, and building's internet wants to be on IP 10.3.3x.xxx
I couldn't figure out how to get my antminers working until I changed the protocol of the WAN to DHCP (without saving)
going back to the interface tab, and restarting the WAN, I was immediately kicked off the direct IP 192.168.1.99 without any access to the antminers, but they started hashing at the pool.
Fortunately I can restore access by power down/power up the ants, which returns the WAN to static IP. In order to get them hashing again, I need to redo the WAN change above.
You have a working formula so I'd just stick with it. Unlike Avalons, you don't really ever have to check in with the AntMiners as theres no stock overclocking or voltage/fan tweaking.
