Hi, I apologize, but I don't understand this very well.
If i'm on a Machine with IP 10.5.0.32 and want to sent a packet to
10.6.0.20, I don't want the packet to go out to the public but to
10.5.0.6 because that is my gateway to 10.6.0.0/24 <http://10.6.0.0/24>.
I am not filtering traffic or do any port forwarding. I want to add a
route to 10.6.0.0/24 <http://10.6.0.0/24> on 10.5.0.1 gateway.
my understand was to do something like this:
cat /etc/network/interfaces
iface eth0 inet static
address 10.5.0.1
netmask 255.255.255.0
gateway public IP
up route add -net 10.6.0.0 netmask 255.0.0.0 gw 10.5.0.6 dev eth0
this does not work because then all traffic gets routed to that interface, 10.5.0.6 including public traffic.
Thanks,

Thank you for your reply,
default gateway for 10.75.0.0/24 <http://10.75.0.0/24>
<http://10.75.0.0/24> is 10.75.0.1
if I ran the following command on gateway machine (10.5.0.1)
ip route add 10.6.0.0/24 <http://10.6.0.0/24>
<http://10.6.0.0/24> via 10.5.0.6 dev eth0
any traffic bound for 10.6.0.0/24 <http://10.6.0.0/24>
<http://10.6.0.0/24> gets re-directed
to 10.5.0.6, but only that machine. I have not configure iptables or
port forwarding. can you point a direction on how to accomplish
that step?
Thanks,

Hi All,
I'm new to this list, I want to thank you all for
support in
advance.
I have a router running Debian with one interface
facing public
and 2nd
interface to a LAN 10.5.0.0/24 <http://10.5.0.0/24>
<http://10.5.0.0/24>
<http://10.5.0.0/24>.
I have a 2nd router one interface on 10.5.0.0/24
<http://10.5.0.0/24>
<http://10.5.0.0/24> <http://10.5.0.0/24>
and 2nd interface facing another LAN 10.6.0.0/24
<http://10.6.0.0/24>
<http://10.6.0.0/24> <http://10.6.0.0/24>.
So I want 10.5.0.0/24 <http://10.5.0.0/24>
<http://10.5.0.0/24> <http://10.5.0.0/24>
to be able to access
10.6.0.0/24 <http://10.6.0.0/24> <http://10.6.0.0/24>
<http://10.6.0.0/24>. I did the
following for a temporary
work around.
ip route add 10.6.0.0/24 <http://10.6.0.0/24>
<http://10.6.0.0/24>
<http://10.6.0.0/24> via 10.5.0.6 dev eth0
this works fine but if I log in to another machine in
10.5.0.0/24 <http://10.5.0.0/24> <http://10.5.0.0/24>
<http://10.5.0.0/24> network, I'm unable to access
10.6.0.0/24 <http://10.6.0.0/24>
<http://10.6.0.0/24>
<http://10.6.0.0/24>
can you please help? I have Linux 3.2.0-4-686 Debian 3.2
Thanks in advance!
Hi!
What is the default gateway for the network 10.5.X.X? The
default
gateway of 10.5.X.X known the route for the 10.6.X.X network?
Some iptables rules are applied? Port forwarding has
configured?
Regards. Fernando.

Hi!
You only need configure port forwarding in the default gateway of
10.5.X.X because it is the bridge between boths networks. Clients of
boths without routes of the other, send thats packets to the default
gateways.
If all is right, both networks are connected and you can use
iptables o whatever to filter any traffic or configure NAT between
networks.
You can find a lot of information of port forwarding in google[1],
for example[2]
