[c-nsp] NAT question

[Marc Steiniger]

Hi Raz,

The easiest solution is to configure your internal DNS server to
resolve to the internal (LAN, private) IP address, while your external
DNS servers resolve to the public IP address.

Should this not be possible, I believe it would ultimately this is
possible with dns fixup PIX 6.3 and newer (or 'alias' with 6.2 and
older).  Simply create your static mapping appending the word "dns" to
the end.  This will result in DNS record translation:

static (inside,outside) x.x.x.x y.y.y.y dns

where x.x.x.x is the public IP address, and y.y.y.y is the private LAN address.
