I do HyperBackups every night to a remote target-DS - it used to work fine for years now.
Recently, I replaced the old router (Netgear) on the target-site with a new Synology RT2600ac.
Since this "upgrade" I get HyperBackup errors and also the entire WAN access breaks down (on the target site) for ~20min after HyperBackup starts.
On the source-site I get the following message:
The RT2600ac default MTU value is: 1492 - which I didn't change.
Data-Replications works fine without any issues (same source / target NAS like HyperBackup).
Any hints where to start the trial/error game?
Thank you!

PS: source is a coax (cable) line; target ADSL;
