Fw: Shorewall with Debian
Checked:
IP_FORWARDING=On
Another things that bothering me
I am using class A network as 10.1.1.x/24, subnet 255.0.0.0
Isn't this is OK for private network?
I used this IP to set up few offices using Winblow AD and it is always working OK
Anyone want to comment on this?
Off course any answer for my solution always warmly welcome... :)
And yes, I did read the 'two-interfaces' and 'three-interfaces' examples
This is why I post my questions, because I still can't make it work.... :(
Cheers

1. Check /etc/shorewall/shorewall.conf and make sure
IP_FORWARDING=Off is really
IP_FORWARDING=On
reading through all the shorewall-doc package helped me tremendously.
admittedly it took me a couple times to get it right.
My setup is 3 nic as well though I have two 'net' and one loc.
aptitude install shorewall-doc
;-) good luck.
