Yes, remote currently acts as a road warrior. If there's any good solutions
that require my network to have another topology - feel free to suggest
your thoughts :) Note that a remote has the same IP address all the time
and is always connected.
I have a similar idea about a GRE tunnel. For example, make a GRE tunnel
within a dedicated network namespace and include the process to this
namespace. However, maybe there's something more elegant? For example,
using iptables to mark packets and make custom routes.
