Can A PC On VLAN1 Access VLAN2?

[SonnyB]

Hi,

Our Meraki is configured to auto assign IP's to PC's and VOIP phones, isolating the 2 on different subnets. 

Is there a way for a PC that is on the PC subnet to access the VOIP subnet? 

In the past, in a similar situation without using VLAN's, I would assign the PC a static IP, gateway, that was used for the PC subnet and also the VOIP subnet. From there, I could access either networks.

For example, 

PC Subnet is

IP: 192.168.10.xxx

Sub: 255.255.255.0

Gate: 192.168.10.254

VOIP Subnet is

IP: 192.68.50.xxx

Sub: 255.255.255.0

Gate: 192.168.50.254

Any suggestions are greatly appreciated.

Thank you very much,

Sonny

Yes, definitely. Do you have a MX? If the MX is the default gateway for each network, you don't need an additional configuration.

Just to be sure, do you have any firewall rule?

Also try disabling the local firewall on the machines.

Hi @alemabrahao , yes, our is a MX. At the moment, there are no firewall rules. I think the MX is the default gateway. I'm trying to confirm it's IP.

You have configured two subnets both on the same VLAN? If so thats not good practise and for VOIP systems would mean network could be noisy of client devices are sending a lot of traffic such as multicast.

If you have them on seperate VLANS then you could setup route if using a layer 3 switch, if you don't have a layout 3 switch you would need a router/firewall like a Meraki MX or Fortigate.

Hi @BlakeRichardson sorry for the confusion. 

VLAN1 (PC's)

has its own unique subnet.

Example: 192.168.10.xxx

VLAN2 (VOIP's)

has its own unique subnet.

Example: 192.168.50.xxx

Cool. Ours is a Meraki MX. I'm guessing that I just need to find which port the PC we're dedicating this to and then change it from VLAN1 to VLAN2? 

[alemabrahao · Accepted solution]

Are both PC and server connected directly to the MX?

If so, you have to configure the port where they are connected in their respective VLANs.

This is actually a very simple setup.

Thank you very much. I had to locate the PC's IP to find the port it was on and then switched it from VLAN1 to VLAN2. 

Cheers.
