Hello all, I have a Cisco PIX 501 version 6.3(5). It is deployed in an office with 10 PCs, all with web access. Every day (at different times) one or two of the PCs will lose internet browsing connectivity. When they are unable to browse I can still ping internet hosts i.e. yahoo.com. If I reboot the PIX connectivity is restored. Has this got something to do with the PIX losing it's ARP cache? I reloaded the software (went from 6.3.(4) to 6.3(5)) and it still does this daily. The ARP timeout is set to the 4 hour default. Please see config below and thank you very much for any help you can give.
