you haven’t mentioned your firewall or router config between the private corporate network and the public internet (or I missed it). Cisco firewalls and I bet others too, have a very interesting and powerful capability – to examine and edit/change packet data (payload data) on the fly in real-t

Hi Nick. First question, does the internal zone *have* to keep the same name? As has been said already, this is a fairly common setup done by people a long time ago who usually didn't think through the consequences of their actions.

Unfortunately, redesigning the internal zone is way beyond the scope of what I can do, but thanks for the info. On 04/11/2023 13:40, Greg Choules wrote: Hi Nick. First question, does the internal zone *have* to keep the same name? As has been said already, this is a fairly common setup done by

As on other replies, a different internal zone is a huge project for the company, not a quick win, unfortunately. On 04/11/2023 08:55, Michael Richardson wrote: Given VPNs, RemoteAccess and the like, I strongly recommend against split-DNS configurations. They were great ideas in 1993, when all

Given VPNs, RemoteAccess and the like, I strongly recommend against split-DNS configurations. They were great ideas in 1993, when all sites were concave, but that's just not the case anymore. Instead, I recommend having a sub-zone, "internal.example.com", or some other convenient name. Put a zo

It means something in your network sent a query containing the literal URL below. The message is just misleading - the resolver tries to do QNAME minimization on it, it fails, switches to full name which ends with NXDOMAIN from root. Ondrej -- Ondřej Surý — ISC (He/Him) My working hours and yo
