Reduce OpenVPN AS data usage

TomasCrespo

Hi! I have successed installing OpenVPN AS. It is working perfectly

However I have one client (a Rpi with raspbian) that consumes 20MB/daily in idle status, I mean without using the connection for nothing.

Do you think this values are right or are too much?

This client is on a 3G pay per use data connection, so I have to pay for 600MB/month even not using the connection.

Could I tweak some configuration to reduce this data use?

Thanks
