Hello!

We have an leased line to the internet with only one oficial IP. The
Exchange Server is standing in the internal LAN and has a private IP.
Is it possible, to route any traffic from tcp/25 to the oficial
address to the internal address?

Regards

Martin

Hello Martin,

yes, this possible via the static command.

Example:

static (inside,outside) tcp official-ip 25 internal-ip 25 netmask
255.255.255.255

additionaly see the following site:

:yes, this possible via the static command.

:static (inside,outside) tcp official-ip 25 internal-ip 25 netmask 255.255.255.255

As there is only one external IP, instead of "official-ip" in the
above, one would have to use the keyword "interface".

static (inside,outside) tcp interface 25 internal-ip 25 netmask 255.255.255.255
