Mikrotik client for cisco vpn concentrator

Hi all.

As I see, Mikrotik can’t connect to cisco vpn concentrator?

Currently I connect to it with linux box, using vpnc.

(http://www.unix-ag.uni-kl.de/~massar/vpnc/)

…and it works flawlessly, but I would like to replace my linux boxes with routerboards.
I don’t know what protocol this is, all I have is

IPSec gateway
IPSec ID
IPSec secret
Xauth username
Xauth password

…and as I can see, there is no way to create such connection on Mtik. I don’t have access to Cisco router, so I can’t configure normal IPSEC.
