The Cisco VPN with TCP-transport is realy doesn't work.
Note: Cisco AnyConnect VPN Client afaik is using another method of secure-connection, so only old environments are affected.
To make the Cisco VPN work in Shared Networking please switch Cisco VPN to use UDP transport:
In Cisco VPN Client: select the connection, click Modify icon in toolbar -> choose Transport tab and switch to the IPsec over UDP
