I have an odd problem I am hoping someone can help me with.
I have a Pix 515 firewall Restricted with 16MB Flash and 64MB RAM. Whenever I tried to boot it with version 7.0.8 or 8.0.4, the firewall stays up for about 5 minutes and then it reboot itself every five minutes. With version 7.2.3, it seems to be stable to stay up without reboot.
My configuration is very simple:
nat (inside) 1 0 0
global (outside) 1 interface
access-list External permit ip any any log
access-group External in interface outside
Anyone run into this issue before? Thanks in advance
