Multiple Subnets with one router
Posted on 2007-11-25
We are currently running a really great switch with a really lame router in our office and I need to see if its possible to do a complicated configuration with this setup.
We have the following:
Cisco Catalyst 2950 Switch
Linksys wrt300n router
Cable internet connection
I have run into the need to setup 2 separate Windows Small Business Server 2003 networks using the equipment above. I am a beginner to trunking and vlans and I'm wondering if it is possible to set something like this up. I know that the cisco can to vlans but not exactly sure how to configure this (I think I've done it but not sure). I'm also not sure how to make 2 vlans on 2 different subnets not see each other but see and use the same router (what ip should the router have?). In the end I'd like to have something like the following:
Windows Small Business Server as domain controller, dhcp, DNS etc.
@ IP 192.168.10.1, 255.255.255.0
Windows Small Business SErver as domain controller, DHCP, DNS etc.
@ IP 192.168.1.1, 255.255.255.0
Both networks using Linksys WRT300n as the gateway to the internet (not sure what the IP of the linksys should be)
I think I've got the VLANs setup via cisco network assistant but can't be sure as I'm a noob.
Basically I left everything alone except gave port 24 (where the second SBS server will connect to) the following settings:
Admin Mode - Static Access
Static Access VLAN - 2
I also changed the settings of Port 1 to the following for trunking (this is the port that connects to the linksys)
Admin Mode - 802.1q Trunk
Trunk Allowed Vlans - ALL
Pruning Vlans - 2-1001
Native Vlan - 1
All other ports were left to their defaults which appear to be vlan 1
Currently the router is setup at IP 192.168.10.254
I've got one SBS working but it is on VLAN 1 and has an IP of 192.168.10.1,255.255.255.0
I can't seem to get the other SBS working on VLAN 2 with and IP of 192.168.1.1
I've tried with a subnet of 255.255.255.0 and 255.255.0.0 and still nothing.
Can someone please advise me as to how to get this working (or if its even possible). Is my switch config right? What should the router IP be? What should the network settings on the SBS servers be? What else am I missing.
Thanks much in advance for any help.
