I have encountered one difficult problem, I wished all expert could give my - newie some tips,
One ASA 5505 - ASA 7.2(1) and ASDM 5.2(1)
One ASA 5510 - ASA 7.2 (1) and ASDM 5.2(1)
These two firewall make site-to-site VPN connection
two ASA has three interface - the one is inside (security level is 100), the another is outside (security level is 0), the finally interface is metro (security level is also 100)
***** I didn't know why around 3 days to one week , these two ASA would hang and make all internal PC cannot access to internet, it need to uplug and replug power, and then the ASA resumed. I didn't know how to shooting this problem, is ASA version is old (7.2(1)), or other problem,
***** I didn't know how to see the log, in the matter of fact, I have already set up a syslog in the one windows server, but I see log, I found no any error log for ASA error or hang message, please everyone.
