Will VLANs solve this problem?

[beye1850]

I have 8 separate LANs
Each LAN has 5 nodes
The IP addresses of the nodes are 10.11.10.1 to 10.11.10.5 (this cannot be changed)
I need the nodes on all 8 LANs to be able to connect to a server on another LAN

If I setup a VLAN for each of the 8 LANs plus 1 VLAN for the server on a 2950 Cisco Switch, will this allow all the nodes to connect to my server, or will I recieve IP conflicts since each LAN has the same IP addresses in use?

Thanks for the help

I dont believe so. The 2950 cannot do that.
Network devices in different VLANs cannot communicate with one another without a router to forward traffic between the VLANs

Im sorry I forgot mention that we also have a 1700 Series Router which can handle the communications between the VLANs

You would still get IP conflict.

Your best bet is to get a router and implement Network Address Translation on each LAN interface (be it a VLAN interface or a physical LAN interface). That way the node addresses will appear as separate individual entities to the server and fix your duplicate address issue.

Hope this helps ( and makes sense).

Hi,
It seems unrealistic that you cannot change the IP addresses of only a few hosts to make your life a lot easier!!

My 2p worth.
Phil. If everything is coming your way then you're in the wrong lane.

I somewhat agree but sometimes the mountain must come to Mohammed. Maybe this gets around licensing? Terry?
