Hi all,

1) Dedicated Firewall
2) Server
3) Clients

It is a switched network and the 'Server' has only one interface card=20
connected to the switch. The 'Server' can only access the internet as i hav=
e=20
specially blocked the clients on the 'Dedicated Firewall'. Now what i want=
=20
is that=20

1) When clients connect to the smtp port of the 'Server' they are redirecte=
d=20
to the another smtp server on the internet. One more thing my 'Server' is=
=20
not listening on port 25 i just want to have a behaviour of port redirector=
.=20
Redirecting connections destined to the 'Serve' on port 25 to a specific=20
server on the internet.

2) Now in this case i wanted to have the behaviour of proxy server. Wheneve=
r=20
client connects to any ftp (or any other service) server on the internet=20
they are silently proxied thru the 'Server' as 'Server' can only access the=
=20
internet.

My clients gateway is set to 'Server'

Is that possible to achieve thru iptables if yes can someone give me a=20
direction or iptables script how to accompalish that.

Thanks...
