Answer 1

Cisco SSL VPN (aka AnyConnect) is configured like this:
www.cisco.com/c/en/us/td/docs/security/asa/asa80/c...
But it is not compatible with OpenVPN. For compatibility, you need to use an open analogue of OpenConnect. But I don’t know if it’s possible to drag it into your router.
By the way, I did not find a sane description of this piece of iron. But it is clear that it contains Linux. Does it happen to have more standard IPSEC or GRE in it?

Answer 2

that's just the point, that only pptp (which does not suit) and OpenVPN. thanks for the answer. We'll keep thinking.
