add subnet to dhcp, make bridge ?

[hellbeach]

Hello
At the moment we have one subnet in the network (10.40.40.*) and now we are starting to run out of ip´s. I am going to add 10.40.41.* as an additional subnet and I need some guiding.
How can I make the communication work between the two subnets ? So that for example 10.40.40.10 can ping 10.40.41.20..

We are using a novell 5 server for dhcp and routing.

what mask are you currently using?
do you have multiple sites - are their sites connected to your sites via any routers?
how does your connection to outside world work - any nat etc involved

All I really need to know if how I can make the "bridge" work on my local LAN and then I will work on it from there.
I´m using 255.255.255.0 as mask right now.
But can´t I just put an ip-forward in static routing from one subnet to another, or something like that ?

Lets say I have two subnets:
192.168.0.*
and
192.168.1.*
What is the best way to get the communication between these subnets to work. So I can ping from one subnet to another.
Do I have to set up some kind of routing or can it be solved in some other way ?

yes you would need some kind of routing -

i'm assuming that you are a single site and using 10's internally with no routers etc

if this is the case than it may be easier to modify the subnet mask to incresase the numbers - this shouldnt be undertaken lightly though as it has certain ramifivations

ie static addresses would need modified and dhcp would need to be altered to issue the new details

What should the subnet mask be for this to work (it´s 255.255.255.0 at the moment)

need to work it out with the numbers you are using

a mask of 255.255.254.0 will give you 508 numbers instead of the 254 that a 255.255.255.0 will give

you need to check that this will fit into your structure as things would need to change
