Hi. We have a Cisco ASA 5505 firewall as the gateway for our small (2 servers, 7 workstations) office network.
Recently, one of our workstations has been intermittently losing internet access (not network access, just internet). I don't see anything apparent on the workstation, but I believe that it be a licensing issue with the ASA. Unfortunately I have little experience with the firewall.
The workstation in question is configured correctly network-wise (static address, only using the internal DC for DNS).
My first question is how can I tell how many users the box is licensed to support? My hunch is that we are licensed for 10 and are intermittently ending up with 11 devices on the network (somebody's ipod or smartphone my be coming and going on the wireless).
If this is a licensing issue, I should be able to find some sort of message within the firewall stating that it is blocking access for 'Node X' or IP address x.x.x.x due to licensing restrictions, shouldn't I?'
If I look at the ARP table, I am seeing 10 entries currently. At this time, I can access the web from all workstations in the building.
Any help would be appreciated... this is extremely frustrating for the one user who continually seems to be getting bumped.
