Publishing a mail server

[Lukey]

When I try to use the publish a mail server wizard, I get the error message that there are 'no external IP addresses currently available'

This cannot be true as our ISA server holds an external IP address and we are on a leased line ISDN connection.

Just wondered if someone could point me in the right direction or let me know if I am missing a setting somewhere as I think that this should be quite straight forward.

Many thanks

You should have 2 NIC, one with the local address and the 2nd one with the external ip no DHCP, connected to you isnd router.
Is this your case?
