CISCO SSL VPN Server with Mikrotik as Client

RouterOS General
1

Is it possible to connect to a remote CISCO SSL VPN (authenticated with group/username/password) using a Mikrotik Routerboard (RB760iGS - 6.46.4)?
I tried to use SSTP Client but always get

SSTP_DUPLEX_POST /sra_{BA195980-CD49-458b-9E23-C84EE0ADCD75}/ HTTP/1.1
Content-Length: 18446744073709551615
Host: 0.0.0.0
Client: terminating… - closed by remote peer

Any help?

Thank you.

No, this type connection it’s not possible - RouterOS doesn’t support Cisco SSL VPN. SSTP (Secure Socket Tunneling Protocol) is proprietary VPN protocol from Microsoft. Cisco SSL VPN (or WebVPN) is proprietary Cisco solution (based on SSL / DTLS protocols ) . They are not compatible.

You can do this with a Linux system acting as the client though.
