I’ve configured forwarder in DNS in zeroshell so I get internet dns from my ISP.
some time if I dnslookup to local host in zeroshell it’s not up to date. to flush the cache I have to set dns inactive and set back active. (and during this time forward doesn’t work). Is there a way to flush it without deactivate it.
And where do I set the delay between to refresh of this cache.
Thanks
