make sure the stratum proxy is turned on in the settings, then scan hardware (shouldnt need to scan in newer versions) then righ clock the proxy device, set the coin it is to mine, then click start.
If you close MultiMiner, and reopen it, then you need to click start again.
then point all your miners to the MultiMiner box IP address and the port for stratum or http port of your proxy. Ensure any firewalls have the port set to open (eg windows firewall).
Thanks, but it still does not work. I created a new Inbound Rule in Win7 firewall called Stratum Proxy to open 3333 to all. I have enabled Stratum port 3333 under Advanced miner settings/Proxy settings. I've scanned hardware and see all my S3s in MuM under Network. I saw somewhere that if they're mining via the stratum proxy that they stop appearing under Network. In the section called Proxy I checked the box Stratum Proxy #1 that says it's mining BitCoin.
MuM is set to "Begin mining when the app starts" and I've also tried clicking the Restart below the Stop button.
How do I point an S3

I entered stratum+tcp://192.168.1.253:3333 under Miner Configuration Pool 1. I left worker and password blank. I also tried 192.168.1.253:3333.
This PC is running MuM 3.8.1 with IP address 192.168.1.253
TIA
