People:
           I=B4m new using iptables and i want to know if it is possibl=
e=20
to forward all the packages to a specific port to a specifica ip=20
address. This is my environment and what i need to do:

I have a lan under 190.168.0.x

then a have a gateway with iptables + ipcop to filter all packages to=20
WAN (internet)

My ISP give us a set o public ips and all the packages from the lan to=20
the wan use one public ip (one from that set) =3D 190..139.106.194

Currently our smtp server is been considered as SPAM for a few domains=20
(and we need to change this ASAP).

It is poosible to configure iptables to set all the packages from=20
190.168.0.x:25 (smtp port) to use a different public ip addres of the=20
set that our isp gives us?

brieflly:

all packages from our lan to a port different to 25 use 190..139.106.19=
4=20
and all packages from our lan to port 25 use 190.139.106.195

Thanks in advance!
