25Mbit/s. The connection is for sure not the limiting factor. Uplinks is
used for ~350Kb/s while the downlink even uses less during the "backup".

How should this do any harm? The router is a totally different pc.
Shouldn't the cpu usage be high at least if OpenVPN settings would
interfere here?

What do you mean? I do not want to use direct connections as I have to
do a port forward in this case.
