Extend LAN IP Range

I need to extend my network.
I have two sites, site1: & site2:
There is a router that forwards all packets from one site to the other.
We are running out of ips in the 11 network (site2).
I was wondering what is the best way to go about extending the netowork ip range at site 2.

Thanks for your advice/help

If you have a Cisco router, you could add a second subnet with the "ip address secondary" command applied to the LAN interface.  Otherwise, you will need to remove (re-IP) the network and replace it with and a subnet mask of  This would give you an IP range of all the way through for a total of over 500 available IP's.  It's very important that you don't just apply the subnet mask to the existing network, as it would then overlap with the subnet and cause problems.

hi there!
there are two options possible,as was mentioned by bigcurefan
still I want to caution you, that extending physical broadcast domain to more than 256 hosts is not recommended.
i would recommend configuring separate vlan for each of /24 subnets and route them via one interface of your router if you have no spare one.
