PIX 525 stops traffic at inside interface

Unanswered Question
Jun 18th, 2007

After 9 or 10 hours of normal operation the pix stops traffic at the inside interface. It's a PIX 525 with PIX 6.3(5). Logging is disabled at all - so I guess no problem with the syslog service. Any ideas or recommendations where to start troubleshooting?


I have this problem too.

Try these steps:

1.Check cable connectivity on the inside interface.

2. Check the status of Inside interface, whether its up or down.

3. Clear ARP table using the cmd "clear arp".

4. lowering the arp timeout , may solve this problem

Note:Ideally, the PIX should have an arp timeout of 14400 seconds, and there should not be any need in lowering this timeout value. Additionally, any value less than 60 seconds is not recommended and will result in an error message warning that ARP cache timeout values less than 60 seconds may cause packet loss.

has this always been a problem?

what license do you have?

what is your NAT setup?
