M4300
Hi All, I currently have a set up as follows Vlan 10 - 200.0.10.1 Vlan 20 - 200.0.20.1 Vlan 30 - 200.0.30.1 Vlan 40 - 200.0.40.1 Vlan 100 - 200.0.100.1 Vlan 250 - 200.0.250.1 Interne...
Hi Jens,
Thank you for your reply.
We do have routing within the switch through the various vlans etc so vlan 10 devices can talk to vlan 20 devices etc. This is done through the switch and not a router.
We are currently running all /24 subnets
The issue i am having is not the inter vlans connections but getting the devices to route to the gateway 200.0.100.254 i will attach my current config of the switch which will hopefully flag an issue with my config.
Thank you very much,
Nick
Hi Nick,
shot into to dark: does your Internet gateway know where to route packets in the direction of your VLANs? You'll likely have to add static routes for the subnets not local to your Internet gateway, all pointing to the routing interface 200.0.100.250.
> This is done through the switch and not a router
sorry for my old-school use of words: To me, the M4300 is (as configured by you) both a switch (for layer2 traffic) and an IP router. Whereas your external Internet gateway may be "just a router", or firewall, or whatever. To me, any IP node connected to more than one IP subnet and routing traffic between them is (in some cases "also") a router ;)
Regards,
Jens

Yes Jens! The router will only send packets to the LAN interface for the attached subnetwork, any other packets will be directed to the default gageway, and that's the Internet then.
Consider adding a policy route for the other VLAN subnetworks to the router LAN interface, or a static route to the switch attached LAN IP.
