Thank you very much.

Currently we do not have a way to flush the DNS cache unfortunately. The DNS cache is hold in the memory used by MWG so a process restarts clears the cache (but interrupts the users, of course). For the underlying operating system I am not aware of any cache.

In the Configuration -> Proxy -> DNS section of the UI you have some more options for the DNS cache. If you see issues more often, probably you may want to reduce the maximum TTL.

If you can tell more about the problem, maybe there is another solution we can think about.

Best,

ANdre

Hi Andre

In the current MWG Main Release version 7.3.2.10 there is now the possibility to flush the DNS Cache.

In MWG Admin WebUI goto:

Configuration | Appliances | <gateway> | Proxies (HTTP(S), FTP, ICAP and IM) | DNS Settings | klick "Flush DNS Cache" button

I do not know when this feature was introduced.

Regards,

Tom E.
