RE: [PLUG] problems uploading through browser/ftping
|
Ok.... so I'm starting to get it.
I've determined that my firewall works... but is somewhat retarded and there's nothing I could do to fix that thing in this case. (That's why it was so cheap, eh?)
Dumb question #2. If I dump my router and throw in another network card in and use the webserver as a router, that'll work, right?
Is PPPoE in linux super evil to set up? Has anyone played with the gui connection sharing thing in Mandrake 8.2?
Thanks for your help, guys... I really appreciate it. This is finally starting to make sense...

The 192.168.x.x are private ip addresses that anyone can use. You
cannot connect to a private ip address from outside the local net cannot
be reached. Now if you set up port forwarding so that port 80 gets sent
to the web server, port 22 gets sent to the ssh server that you allow
access to from the outside,
Your firewall will have a minimum of 2 ethernet cards with eth0 having
the real IP address and the other ethernet cards reflecting the local ip
address. Also you need to set up port forwarding to work from inside
your local network to the outside.
# This allows your local port 25 to get out toi the outside world
iptables -t nat -A POSTROUTING -o eth0 -p tcp -s 192.168.1.0/16 --dport
25 \
-j SNAT --to 64.194.227.197
# This allows mail from the Internet to get to your mail server
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 25 \
-j DNAT --to 192.168.10.1
Now you were talking about ftp specifically and for ftp to work you need
to port forward both ftp and ftp-data
