Are
you sure you want clear text passwords being passed across the internet? You would be served much better using
ssh instead. Whichever you
choose, you can do either with iptables.
iptables
–A prerouting –t nat –p TCP –d <external static IP address> --dport
<port you want routed to the internal SCO box> -j dnat --to <IP
address of the SCO box>:<port number you want the port that is being
forwarded to arrive on at the SCO box>
ex:
iptables –A prerouting –t nat –p TCP –d 213.23.45.2 --dport 22 –j dnat --to
192.168.0.5:22
if you
want this to be port 10000 on the firewall then you can do--dport 10000 and
–to 192.168.0.5:22
You
will then need a line for the port as
follows:
iptables
–A FORWARD –i eth<number of the external ethernet card> -p tcp --dport
<port number on firewall>
-j ACCEPT
ex:
iptables –A FORWARD –i eth0 -p tcp --dport 10000 -j
ACCEPT
Again,
I would strongly discourage using telnet across the
Internet.

Subject: IPTABLES Routing
Here is
my situation:
I have
a Redhat 8.0 server setup as a DSL gateway/firewall using 2 network cards. One
NIC for the internal IP and other with the public IP.
We have
a SCO server that we telnet to from our internal network. This server is setup
with a modem for when we want to connect to it from a remote location. But now
we would like to connect to it remotely through the
Internet.
So my
question is, can our Redhat 8.0 server be setup so that we can telnet
into it, then have it redirect incoming telnet connection to the SCO
server on our private network?
Is this
possible, or must I also setup the SCO server with it's own public IP
address?
Can
this be done with IPTABLES or other, if so how can I go about doing
this?
Your
help is appreciated.
