OpenVPN client on router?

Question

openvpn

There was a need to put most of the home traffic through the OpenVPN server installed in the Amazon cloud. Since not only computers are connected to the network, but also household devices on which the OpenVPN client cannot be installed, it is supposed to buy a ZyXEL Keenetic Giga router and install the client there.
At the same time, there are torrents that generate excessive traffic, for which Amazon asks for money, as well as some sites that consider visitors from Amazon to be bots. Is it possible and how best to make them work bypassing the OpenVPN client?
All that I have been able to google is mainly about the reverse process, i.e. organizing access to the router and everything behind it through OpenVPN…
Update:I would also be happy with the option when OpenVPN works on the router by default without any traffic filtering, but a direct connection is available for computers. Those. if the router can support two connections at the same time and a particular client can be assigned any of them at any time, this would also be a solution to the problem.

Answer 1

Tell me how to install OpenVPN on Giga?

Answer 2

openwrt ?

Answer 3

2 options come to mind, this is either a cisco router and PBR, or linux with iptables with the ipp2p module and marking packets and sending them bypassing OpenVPN. Plus a simple route table for "some sites that think Amazon visitors are bots."
In principle, if you remember about the smoking rabbit, then I think the 2nd option can be implemented on OpenWRT.
You will have to put the module for iptables there if you decide, the rest is not a problem.

Answer 4

Something tells me that the task is much simpler and can be solved with a regular routing table and static routes
