Good day
My first steps to building a NAT/NAPT
I am trying to understand how the plan9 ip-stack works.
This is what I am trying to do:
I have three ethernet cards in my machine:
Card1: Local address for plan 9 services
Card 2: local gateway for the boxes that dont use plan9
Card 3: Connection to the internet
Each ethernet interface will have a separate ip-stack
Doing like this I hope to separate plan9 services from the gateway,
to make my environment fairly secure.
Plan9 will not use the gateway interface, I will just import the internet interface when I want to access the outside world from the
plan9 machines.
If I open the data file in the gateway stack /net.gw/ipifc/0/data
from my initial NAT program,
it seems that I don't get any packets on that interface when
I try to access some outside ip-address from the non-plan9 machines.
I tried to set up a packet interface on /net.gw/ipifc/1 ,
and added iproutinng to this stack, and when I try to ping this new
interface, from a non-plan9 machine with the gateway set /net.gw/ipifc/0
I get ping reply, but the /net.gw/1/data is also silent.
I might have totally misunderstood something here?
Any suggestions
btw: When I send mail to this list i get the signature <my name> at bredband.net, and gets a lot of spam, is there a way to hide this information?
Thanks
