[Shorewall-users] Shorewall on a file/webserver/router Help

Hi,
     I have a install of shorewall I have 2 interfaces(I think)
ppp0[connection device] and eth0 [LAN device],
I want to allow all traffic from the the internet in or aleast port 80 and
CVS and webmin and mail and everything normal to the main machine with
shorewall on it.

I changed to policy file but it just gave me errors as to double interfaces.
I also what still to alow connection sharing comming from eth0 which is
working now over NAT I think
Is there some way to fully expose the internet interface?
Is there a way to fully expose eth0 from the LAN side?


Im stuck as I can''t even get into the machine from eth0 to edit  the
system
etc.

pctas,
Please read the support page. You haven''t provided enough information
for us to assist you. A small ASCII art diagram of your LAN would be
useful also.

If you want help with your policy file, you''ll need to include it in
your post.

Why are you using a firewall? Full exposure of an interface is what a
firewall is designed to prevent.

Sorry, but we need more information to help you.

Using ssh or telnet? Is the proper deamon running on the machine your
trying to connect to?

Status.txt included

For illustration purposes see  an average basic 2 interface LAN as in the
documentation
http://www.pcaus.com/mazda/BasicLan.png  (40kb)[disregard the wireless
accessponit ]

Yes I very well read the documentation pages located at sourceforge
Therefore my request on this List that maybe someone knew exactly how to
disable the firewall still leaving the NAT translation for connection
sharing intact

The firewall is working very good to good for my liking
I simply wanted to allow all traffic in from the internet on ppp0 for a
webserver and let all traffic out to the internet from the LAN on eth0 to
ppp0 [NAT](already dose this)  and also let the lan be open to filesharing
what have you maybe video(dream on) to.


from the documentation I see arround 4 or 5 files that may need editing ,
 I have observed that it is very possible to allow only one service access
here and there, but, I wanted to know if there was a quick and simple way to
let NAT translation take place on all interfaces without editing tons of
services and ports into the service files and shorewall files

Thansk again
                          O Im not paranoided or worried about access to my
machines/machine

Jesse,
What you''re asking for is a router with NAT. Shorewall is a firewall. I
suggest you remove Shorewall, and read the following documentation. It
describes NAT configuration.

http://tldp.org/HOWTO/IP-Masquerade-HOWTO/index.html
http://tldp.org/HOWTO/Masquerading-Simple-HOWTO/index.html

I have a feeling you may need these instructions. Follow them after you
discover your network has been compromised.

    * Remain calm; don''t hurry.
    * Notify your organization''s management.
    * Provide a game plan (with options if possible).
    * Apply need-to-know.
    * Use out-of-band communications; avoid email and other
      network-based communications channels.
    * Take good notes, good enough to serve as evidence in a court of
      law.
    * Contain the problem; pull the network cable.
    * Back up the system(s), and collect evidence.
    * Eradicate the problem and get back in business.
    * Lessons learned, apply what you have learned.

Bridging/Proxy-ARP, a DMZ, and ez-ipupdate is what you should look into.

You''re right - the line below is in error. It should read:
"Shorewall Masquerading not made for simpletons"

I announced a week ago that until further notice, I wouldn''t be
involved in
Shorewall support or development. And I have been maintaining a low profile 
since then.

I knew that Tom - I was just kidding because it seems like you only took a few
hours off!

Tom''s been lurking.... 

He needs to go do some salmon fishing or do some hiking\Skiing up in the
high country and take a good break ..... 

I subscribe to several lists and you will always see someone once in a while
pop-up with a bad attitude and he\she usually will not get any help from
anyone after they do that. This has been a great list thanks to Tom''s
hard
work and dedication and I believe that it will continue to be a great list. 

Tom you need the time off to be with your family and loved one''s and
hopefully some of the people who have been helping out on the list will
continue to do so and we will all continue to learn from each other.

Cheers,
Mike
