DNS Doctoring SA520 (W)

Unanswered Question
Jun 14th, 2010

Hi there

We recently swapped a cheap RV042 with a SA520W, doing NAT overload for the office (1 public IP address).

There's also a small web server running internally and the SA520 is doing port translation for this server on port 443 (https), which has a hostname. This hostname resolves to the public IP address, there's no DNS resolver running inside, clients behind the NAT use Google's free resolvers ( and

With the earlier RV042 connecting to this internal server was never a problem and worked automagically. I think the RV042 was doing "dns doctoring" and did a rewrite on DNS replies which contained the public ip address on the WAN port.

Does the SA520 support this kind of thing?


I have this problem too.
