Hi,

Just acquired a 2820vn, and having fun with it. Upgraded to 3.3.5.1_232201

Public IP Address is 81.x.x.254, with aliases for .250 and .249.

Web and DNS servers are on the internal private 192.168.x.x subnet as .250 and .249 also.

Services are NAT routed using Port Redirection from Public:port to Private:port e.g.: 81.x.x.250:443 -> 81.x.x.250:443

Also have the public->private mappings in the NAT/Address Mapping section.

Devices on the 192.168.x.x network cannot connect to a service presented through the a public Alias IP 81.x.x.x e.g.: Web port 443.

However the services are accessible when accessed from the internet remotely.

Have seen a lot of references to NAT loopback not working, but cant be sure if this is the case.

Any assistance greatly appreciated!

NAT loopback definitely still broken. It's causing me and my clients a lot of grief. I'm aghast that Draytek break this and over half a year later still haven't fixed it.

Just curious, for situations like this, is there a reason you cannot just use split-DNS?

I.e SBS2008 will create a new DNS zone called remote.domain.co.uk with the host set to the internal IP. That way no loopback is needed as you're talking directly to the internal IP?
