IP masq, forward ?

["Szfelix" <szfelix@freemail.hu>]

I am a new debian user.

I have 2 eth in system, and I want to use as gateway for local net.

in the etc/network/interfaces
----------------------------------------------
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
# The loopback interface
iface lo inet loopback

# The first network card - this entry was created during the Debian
installation
# (network, broadcast and gateway are optional)
 iface eth1 inet static
        address 192.168.0.1
        netmask 255.255.255.0
        network 192.168.0.0
        broadcast 192.168.0.255
#        gateway 195.38.101.206

 iface eth0 inet static
       address 195.38.101.206
       netmask 255.255.254.0
       network 195.38.100.0
       broadcast 195.38.100.255
       gateway 195.38.100.1
   route add -net 195.38.101.206 netmask 255.255.254.0 dev eth0
   route add default gw 195.38.100.1 metric 1 dev eth0
--------------------------------------------------------------
etc/options
---------------------------------------------------------
ip_forward=yes
spoofprotect=yes
syncookies=no
--------------------------------------------------------


I change the WIN2000 server.
The local terminals can ping the output eth card but I can't go out on the
internet.
>From gateway  I can go out.
So simply what and where I must write to resolve this problem.

and, where i can find a documentation, step by step to understand the linux
platform.
I pograming in DOS,WINDOWS since 1990 , so imagine what is in my mind...  :)

I try MAN but I want to understand, to feel the LINUX system.

        Thanx
