Public bug reported:
VPN agent works incorrectly with DVR on multi-node setup. It looks like
VPN agents on network nodes try to find snat namespace which in fact
presents only on one of the nodes, it leads to errors on nodes without
this namespace when IPSec connection is created.
The following errors are observed:
