Routing with a VLANS - changing subnets
I inherited a network on a weird internal subnet (100.100.100.x) the gateway (issued by Windows DHCP server) for clients is a firewall and the switch isn't currently used for routing. I want t...
Here is a quick network diagram which may help visualise this better.
Hi bluesound,
Welcome to our community!
If you wanted to have the 2 VLANs to communicate with each other, then you might need to enable routing on those VLANs. As they are working on 2 different subnets. May I know the model number of your switch? You can also enable routing on your firewall.

Hi there,
I was on holiday for the last week, so I've just got back today, My switch is a NETGEAR GS752TPSB
When I try to tell the netgear to route VLAN 121 to VLAN 1 I get a message.... that I'm not allowed to set up a route on the management vlan. So I tried to change the management VLAN to 100, and set all ports to be untagged on vlan 100 and now I can't manage my switchthrought http OR through the SmartCenter I've a feeling I should have set it to tag vlan 100 rather than untagged, or configured a port with a PVID of 100.I don't suppose you can suggest a fix to this other than a factory reset and restoring the latest backup of my settings.
ThanksChanging the management VLAN will definitely result to unaccessible UI if it is not properly configured. Management VLAN pertains to the VLAN where you can only access the admin page. If you change the Management VLAN to 100, then you can only access the admin page if the computer that you are using is under VLAN 100. Routing is not supported on the switch that you have. You may need to do the routing from your firewall and not from the switch. You may reset the switch to factory default in order to access the admin page again.
