Re: nat ipchains on debian woody


I´m novice on debian, i have decided recently to change from redhat or
mandrake (fatal experiencie in two years), so excuse my ignorance.

First i dont know how to do this step "The first thinng you must do is to
install a kernel with IPTABLES support"
How can I do it ? How can i test if it is on my server?

Second, I  have see this on my server

morpheo:~# apt-get install iptables
Reading Package Lists... Done
Building Dependency Tree... Done
Sorry, iptables is already the newest version.
0 packages upgraded, 0 newly installed, 0 to remove and 0  not upgraded.

It seems to be iptables installed but the previos errors said that iptables
where not avaliable.

Thanks in advance, and for your spanish response, I have a poor english too,

Hello Fraancisco:
The first thinng you must do is to install a kernel with IPTABLES support,
the ipchains is not recomendable for kernels up to 2.4. The kernel packages
of woody distro have this support
Next you MUST install iptables:  ip-tables apt-get install iptables
Then you should enable ip forward and ipfilter, with the instructions early
mentioned by Mark, but if you want to run a proxy ip forward is not necesary

You must read a lot of documentation of Squid and IPtables

Ahora en español,

Hola franciso:

Lo primero que tienes que hacer es bajar un kernel que soporte iptables,
ipchains esta desconntinuado.
Despues tienes que instalar ip-tables apt-get install iptables
Deespues hacer lo que te indicaron con anterioridad habilitar el ip forward
quee no es necesario si vas a poner un proxxy y el ipfilter.

Hay que leer mucha documentaciion de Squid y de IPtabless.
