point your rented rig to your machine, before doing this you need to create a config file in the roaming folder, for your coin
put inside the usual
rpcallowip=192.168.1.*
rpcallowip=127.0.0.1
rpcuser= you choose
rpcpassword=you choose
rpcport=4439
server=1
try to point the rig to 192.168.1.your last ip number of your machine, private ip not public, but i think you need the public ip of your provider here...
Should i sync to wallet first?
Does this method work even the wallet couldn't sync?
The main problem is the wallet couldn't sync due No active nodes and there is no pool also.
