[NBLUG/talk] I think I broke my ping!

[Nat W]

I may just not be understanding your problem but do
you have a hardware
firewall? I am behind a linksys router, but you can
configure to let
certain ports through.

It would muck you up.  You need to digest what it is
you are trying to
do.



To get you started disable the script you are now
using.



Open FIrestarter and run the wizard.



1.  Pick your selected device which is ppp0, also
check the start
firewall on 

dialout option.

2.  Internet connection sharing dialog is next.  Pick
Enable Network
Address 

Translation and select your device ppp0, then enter
your INTERNAL
network 

address range..... or have it autodetect it.

3.  Next dialog, pick the network services you would
like the outside to
have 

access to., or disable all public access.

4.  Next dialog,  Disable TOS filtering you don't need
it.

5.  Next dialog.  ICMP filtering, enable filtering on
the different
types, if 

you want ping to work then UNcheck Echo.

6.  Next dialog.  Save and quit.



make sure firestarter is running with a;



service firestarter start 

from a root prompt

make sure firestarter comes up on boot with a;

chkconfig firestarter on



then check it out... dialup and connect and see if you
can get out from
an 

internal box.  Even if you disabled ICMP on the
firewall box you should
get 

ping to work on one of the internal boxes.



You can fine tune the firewall with the firestarter
gui tool in X.
