Hi,
Its not a problem with the network as such, its your addressing. A few options;
1. Configure a routing device to route between both subnets
2. Change the ip address ranges so both the clients and servers are in the same range.
Cheers

Murphy was right! The server and the clients should be on one network. So the clients will be able to access the server.

So in the Internet, how is it that networks on different networks can communicate with each other? What exactly do you configure on the router that allows it to be able to allow two two different networks communicate with each other? Is a SOHO router capable of this?
thanks

Each IP host has a routing table that defines through which gateway (router) it will access each network to which is no part of. Routers, likewise, have such a table, only that they are configured to also accept traffic from other hosts in one network and forward it to hosts in an other network. Of course they need to have an interface to every network that they will forward packets to and from, in order to do that. Any embedded router and any PC, as long as they have the appropriate interfaces to connect to of all our IP networks (commonly Ethernet adapters, but can also be other types of physical or virtual interfaces), can do that job. The table can be populated statically, by the administrator.
In cases where our network contains many routers and many sub-networks, like in the case of Internet, populating and maintaining the routing table manually is painful, that's why there are several Dynamic Routing protocols, that handle the automatic negotiation to transfer routing information from a router the an other. According to the KISS approach, it is wise to not use dynamic routing unless you have to.
