Hi people!
I habe in a linux machine 2 NIC .

NIC 1 -> 192.168.1.2 broadcast 192.168.1.255 netmask 255.255.255.0"
attached to NIC1 is one DSL Modem.


Question 1:
How will I have to configure nic 2 that both networks don't bite each
other.

Question 2:
How will the clients behind NIC2 (connected to a switch) to be configured?

Put nic 2 in another network, example: 192.168.4.x and give nic 1 as
nic 2's gateway. Be sure to enable net ipv4 forwarding.

Give them 192.168.4.x ip addresses with nic 2 as their gateway.

You tell us.
ifconfig -a

It is up to you what address you give it. (or up to the dhcp server if
you are using that).

You need to create a small subnet. If you want some information about this,
try googling for "creating a subnet".

My config:

# This network configuration was written by net-setup

config_eth0=("192.168.1.2 broadcast 192.168.1.255 netmask 255.255.255.0")
config_eth3=("192.168.2.1 broadcast 192.168.2.255 netmask 255.255.255.0")

dns_domain_lo="heimnetzwerk"

and if i configure a client behind eth3 let us say with:

192.168.2.2, gw: 192.168.2.1 and nameserver: 192.168.2.1

i stil even can't jump with the client in the internet. Ip forwarding is
activated and masquerading too


Here te firehol (firewall) script:
--

server_skypeserv_ports="tcp/9082 udp/9082 tcp/23399 udp/23399"
client_skypeserv_ports="default 23399"

masquerade ppp+

interface eth+ lan
policy accept

interface ppp+ world
protection strong 10/sec 10
server http accept
server https accept
server icmp accept
server skypeserv accept
client all accept

router world2lan inface ppp+ outface eth+
client all accept

router lan2lan inface eth+ outface eth+
route all accept
--

however, I can't jump with the client in the internet. I can ping to the
other machine, but not in the internet. The hell I know why :(

For any advises, I would thank you kindly.
