ASA5520 Spontaneous Reset and Lost DNS

[mallen]

Running an ASA5520 7.0(1)that will periodically "reset". All VPN traffic then gets cut off until we manually re-enter the DNS info that was "saved" to flash. Ideas? Thanks.

What 'DNS' information are you typing in? Typically DNS information isn't used in setting up VPNs.

Our internal DNS -- we simply relay internally to the "real" world. The LAN access of course, does not work without the DNS info in the ASA. There are really two questions here: why the spontaneous reset, and why does saved DNS info not save?

Thanks!

Hello,

What commands are you typing back into the pix that are missing upon reboot? Are you saving the configuration afterwards?

I recently had experience with an ASA5510 which would periodically spontaneously reboot. An upgrade of code fixed the problem.

Via ASDM, under the VPN tab, General tab, Group Policy definition, is a default group policy that contains the primary and secondary DNS IP addresses. Yes, it says it has saved it to flash, but the spontaneous reboot clears this one setting.
