Hi,

There really isn't any "issue"; it works fine. I guess you're looking for
an example of how.

Say your interface is called ppp0. Just add lines to /etc/ipnat.conf like
so:

rdr ppp0 203.57.42.254 port 25 -> 192.168.1.218 port 25
rdr ppp0 203.57.42.254 port 80 -> 192.168.1.220 port 80

I think that from these examples you can figure out the rest.
