How do I portforward webmin/ssl/ssh (the whole world) onto another box


1) https uses ssl.. correct?

2) Do I need to open the port for https/ssl 443 inorder to serve https?

3) I want to foward ssl and webmin to another linux box, how do i do that? I've tried these commands:
$IPT -t nat -A PREROUTING -p tcp --dport 10000 -i $IEXT -j DNAT --to 10.0.0.2
$IPT -A FORWARD -p tcp -i $IEXT -o $IINT -d 10.0.0.2 --dport 10000 -j ACCEPT

are there any other ports that webmin might use?

1. Yes.
2. Yes. "Opening a port" is done by the webserver, the IANA designated port is 443/tcp, but you could SSLify any port, redirect port 80 and 808 to 443 if you want to go SSL-only, etc etc, it's all in how you configure the daemon. *This doesn't count for packages that SSLify their own connections like Webmin using some Perl-SSL module, it doesn't need port 443 open...
3. Run netstat and find out, but I think Webmin only runs 10000/tcp. Btw hope you're aware Webmin has plaintext passwds in older versions...

I've done it..

the webmin service uses port 10000

but the client (browser) uses a range of unprivalaged source ports
hence the final resolution was:
$IPT -t nat -A PREROUTING -p tcp --sport $UNPRIVPORTS --dport 10000 -i $IEXT -j DNAT --to 10.0.0.2
$IPT -A FORWARD -p tcp -i $IEXT --sport $UNPRIVPORTS -o $IINT -d 10.0.0.2--dport 10000 -j ACCEPT
