Hi All.
I'm having a quirky problem with a PIX 501 and was wondering if anyone had any ideas.
Recently I've pulled a PIX 501 out of a closet (having never been used) and configured it for a VPN with my PIX 506e at an offsite location. This offsite location has a PC, Printer, Access Point, and remote VOIP phone. The VPN itself works great, but periodically the PIX just drops some network devices, specifically the Access Point and the Firewall. Both devices stay off until I reboot it (through an SSH connection) they then spring back to life.
Before I go buy another firewall only to have the same thing happen I was wondering if it could be a config issue. Or is this most likely a hardware problem?

Hello Jim,
Have you tried other troubleshooting? like; 'clear arp', try to ping the AP, take captures, see logs, etc.
The PIX firewall is getting to end of support, but further troubleshooting needs to be performed at the moment you have the issue to confirm if this is harware of software.
Regards,
Felipe.

Hi Felipe,
Thanks for responding.
I've tried the following things to no avail:
When the devices drop neither VPN traffic nor local LAN traffic can ping them.
I don't have a good means of capturing traffic, nothing I have in this location has a monitor port.
The timing on the dropping of theses devices is inconsistent as well. It can be anywhere from 30 minutes to 3 days. Lately it seems less than 24 hours passes by before they're dropped.
Thanks,
- Jim
