DNAT to another Network?

[Svavar Örn Eysteinsson <svavar@xxxxxxxx>]

Hi everybody.

I have one question about DNAT.

I have a computer foo.com on an ipaddress xxx.xxx.xxx.xxx

Is there any way for me to DNAT all traffic with destination to foo.com
to another server out-of-town, e.g. computer foobar.com with zzz.zzz.zzz.zzz
that
is not on my public network.?

         |                |         |
         |                |         |
    Network A             |      Network B
         |                |         |
         |                |         |
     Firewall             |    Computer B (final destination)
         |          |-----|
         ->Computer A
