Cisco’s ASA 5505 appliance is ideal for small business environments. We often deploy it in offices with under 10 employees on staff. Single employee can use multiple devices that require internet access. Problem is that low cost ASA 5505s come with a 10 user license (or allow 10 inside hosts).
You can use the show local-host command to see hosts connection information. To determine which inside hosts are using up the connection license show local-host brief | i local host command can be used.
clear local-hosts all command will reset (release) all connections from local hosts.
