----CISCO-- [net a.b.c.0] HOSTB
          |----|-----------|
              HOSTA
                  |-----[slip]----| [net a.b.d.0]
                                HOSTC
                                  |--------------------|
                                                       |
                                                     HOSTD, HOSTE, etc.

The Cisco has a static route for network a.b.d pointing to the ethernet
address of HOSTA.  I would like to set up an access list on the Cisco
which limits incoming TCP connections to net a.b.d to the SMTP port
on HOSTC,  However, I would like any of the hosts on net a.b.d
to be able to initiate connections to anyplace in the rest of the net.
At the same time, I do not want to limit access in any way on net
a.b.c.

The brief description in the gateway manual doesn't make the required
statements leap out at me.  Has anyone done the before who can provide
the boilerplate?

Thanks,
