What should the coinonatx.config file look like on a Ubuntu server, which also contains the wallet with 1000 coins?

rpcallowip=xx.xx.xx.xx
rpcuser=xxx
rpcpassword=xxx
staking=0
server=1
listen=1
port=
masternode=1
masternodeaddr=
masternodeprivkey=

should it contain the externalip=xx.xx.xx.xx instead?
