ok have it , now i generate a mn , but in masternode network always is active 00m:00s ... my config looks so
rpcallowip=127.0.0.1
maxconnections=9
rpcuser=xxxx
rpcpassword=xxxx
rpcport=15394
listen=1
server=1
deamon=1
staking=0
port=17100
masternodeaddr=188.104.8.148:17100
masternode=1
masternodeprivkey=privkey
externalip=192.168.2.102
It looks like your masternode is behind a NAT router. If that's the case, you should create a static mapping (port forwarding rule) on the router for the port 17100. In general running MN on a machine with public IP address would be easier (if you are not so good with networking/routers).
