connection between subnets

[basdijkstra]

i've been trying for a while to create a connection between subnets. http-://dl.dropbox.com/u/712072/technisch%20ontwerp%20tekening.jpg

so the windows xp clients need a connection to a windows 2003 active directory. But if i ping to that network, i get a netwok unreacheable, witch is logical because it is in a different subnet.

Is there a command or something else to resolve this?

edit:
i got a Linux opensuse router. two Windows 2003 Active Directory's, two Windows XP clients to test on and a Linux Opensuse to act as a webserver/backup server.

Hi,
I still have some questions:
Has every Subnet it's own router or is one Router maintaining all subnets?
Are the Router using NAT or just Bridging?
Have you tried altering the routing table of 192.168.1.253 ...
for example:
route add net 10.1.1.1/29 gw 192.168.1.<?subnet1?>

you may post route -n

greetings, Zomby

hi, thanks for the reply.

i have one router and is maintaining all the subnets.
The router is a NAT.

the thing i'm trying is this:
windows 2003 Active directory --> windows xp
10.1.1.3 --> 10.1.1.35

and different.
i can ping from the windows xp client to the network card from the other subnet, but if i ping the windows 2003 server i get 'Destination Protocol Unreachable'

The command you are looking for seems to be iptables.

It manages the firewall and NAT.

Examples:
iptables -L -v -n
iptables -L forward -v -n
iptables -A forward -d 10.1.1.3 -s 10.1.1.32/27 -j ACCEPT
