Cisco 350GX 24 port Switches VLAN configuration doesn't work

[Cinta_87]

We have procured 5 Cisco 350GX 24 port Switches. Each site is connected with one Cisco Switch to Fritzbox 7590.

Current setup:- Fritzbox has an Static IP configured from ISP. DHCP is enabled on the router itself. It has 4 LAN ports and 1 WAN port.

VoIP phones, printers, NAS and PC's are connected to the switch and are part of default Vlan ID 1.

Requirement:- Need to separate all VoiP traffic with PC's traffic by creating separate Vlan's.

Steps implemented:- Created 2 vlans. Devices in Vlan 1 default has internet. 

Created Vlan2 and assigned the switch ports of connected phones to vlan2 but this vlan is not able to reach to the internet since it's part of differnet network range.

How to make these two different networks communicate with each other?

Your help is highly appreciated!!

you need add this subnet to Fritzbox Route back to Switch IP address that is vlan 1 and make new IP range to your NAT List.

Hi,

It seems you have created the VLAN 2 SVI on the Cisco 350XG switch, please add a default route on the switch towards Fritzbox 7590 VLAN 1 interface IP. In Fritzbox 7590, please add the reverse route for VLAN 2 IP Network towards the VLAN1 interface IP configured on the switch (direct connectivity between Fritzbox 7590 and switch).

Voice VLAN (2) traffic will be tagged and data VLAN (1) traffic will be untagged on the switchports. Please apply the VLAN tagging properly on the switch port including the up-link port on the switch and check the service.
