Hi All,

I have one user that get's disconnected and reconnected several times a day, below is the log entries:

I have tried running a ping from the host to the peer and this didn't keep the connection alive.

I have about 20 routes pushed out, is there a limit to the amount of routes?

This user is NOT logged in elsewhere, only one connection.

Should I perhaps have him remove the client profile and allow openvpn to send him a new one?

This is very annoying and has only just started to happen. Only this user has reported this behavior.

Many many thanks!

OK this is happening for several users. It's started since I added a bunch of routes into the system. Is there a max amount of routes?
