I need to connect two office suites that are located in the same building, less than 100 meters apart. Both suites have address schemes of 192.168.0.x. Both suites have a managed switch (Netgear FSM726). These switches do not appear to have VLAN capabilities. There are about 35 devices on each side. It seems to me that changing one side to 192.168.1.x and placing a router between the two sites is the way to go, but I have never done anything like this before.
Is there some better, easier, more secure way of connecting these two sites than using a router? I know that a layer 3 switch could be used, but read this would not support a WAN port, which may be needed in the future. If a router or layer 3 switch is the way to go any thoughts on make/model?
If I need to supply more information, please ask away!
Thanks for any help, Chris
