XE connection problem after using Cisco AnyConnect Client

Question

Hello
I have a rather annoying problem connecting to an XE instance AFTER I have disconnected from a VPN via a Cisco AnyConnect VPN Agent.
Sequence of operations:
- start Oracle XE and work normally
- connect to client's vpn
- do other stuff
- DISCONNECT from Client's VPN
-> unable to connect to XE service any more, unless I reboot
The problem does not happen with other vpn clients like Cisco VPN Service, Juniper, Checkpoint.
Details:
- sqlplus connection WITH service name (eg sqlplus user/pwd@XE): FAILURE with ORA-12170
- but...sqlplus connection WITHOUT service name (eg sqlplus user/pwd): SUCCESS (weird !)
- tnsping XE: TNS-12535 error
- lsnrctl status output (sorry, italian localized)

I have stopped the Win firewall and the problem is still there, so it is not a firewall problem
