Cisco-VPN-Client-v5.x, CiscoAnyConnectIpsecVPN Client, ShrewSoftVPN Clients, some GreenBow Clients and some branches with CiscoBranchRouters running EzVPNRemoteClient. Now a major part of these clients use aggressive-mode with psk and xauth. So iam kind of stuck with no options in the short-term to migrate to main-mode only access. OpenWrt Packages aarch64cortex-a72 Official openconnect8.10-2aarch64cortex-a72.ipk: A VPN client compatible with several SSL VPN implementations (ocserv, Cisco AnyConnect, Juniper, Palo Alto) OpenConnect is an SSL VPN client initially created to support Cisco's AnyConnect SSL VPN. The OpenConnect project is intended to connect to a Cisco Anyconnect server, replacing their proprietary client. OpenConnect is an installable package on OpenWrt. As @WiteWulf said, some configurations of the server may not be compatible.

One of our recent projects required connecting a MikroTik-based office gateway to a client’s Cisco VPN. That task is just a click-away if you have access to a Cisco console or if you can create a support ticket for asking to change or debug VPN settings. We started with only a group name, a group password, and user credentials, which turned the issue into a true challenge. So, if you are in the same situation and cannot check logs or follow official guidelines, check out our solution.
Cisco VPN: Problem overview
By default, a MikroTik RouterBOARD with firmware older than version 5.0 offers an IPsec VPN interface and settings, but Cisco’s proprietory VPN is a modified IPsec, so we were dealing with two incompatible protocols.
Note: This method works only on RouterBOARDs with at least 16 MB of available RAM, the more — the better.
What you need
- RouterOS with the Metrouter package or KVM;
- OpenWrt for MIPS arch with MikroTik kernel patches (or KVM, if you have an x86 board).
Solution
After you load an image to router memory, import the image following instructions.
Import image:
Create an interface for a virtual machine:
Note: OpenWrt provides a DHCP server by default. If you feel that your client might get an incorrect IP, you should block the interface’s MAC address using a firewall while you are configuring.

Change default values to dhcp or your static ip.
After disabling the DHCP server:
Save and restart Dnsmasq:
Switch off MikroTik firewall rule for the metarouter interface (if you have blocked it previously) and restart network on OpenWrt:
Check network address:

Add the route to a remote network on the RouterOS. I added all the routes that the VPN client received.
Use these routes on Openwrt:
10.0.0.0/24 dev tun0 scope link
10.1.1.0/24 dev tun0 scope link
On Mikrotik:
And repeat this procedure for every route.
Additionally, you can add a monitoring script on Cron, which pings the remote network and restarts the connection, if packets become lost:
