VLAN Client Communication Issue

Hi All,

 

I've got an issue on a client site who is using a T1600G-28PS switch.

They are operating a restaurant.

 

Wireless Clients on a VLAN aren't talking to eachother, but can talk to hard wired devices

We are using a Ubiquiti WAP - Client Device Isolation is not turned on.

 

There are some POS printers on ports 1-21.

Port 22 is the WAP

Port 24 is the Feed from the rest of the network.

 

VLAN 1 is the management VLAN - 10.0.0.x/24

VLAN 30 is the POS VLAN - 192.168.9.x/24

 

Port 22 & 24 have a PVID of 1, it is untagged on 1, and tagged on 30.

 

Both devices are connected on the POS WiFi VLAN both are getting IP's in the POS network.

The bunch of printers on VLAN 30 plugged into 1-22 are all printing and can be pinged with no issues.

It seems like it's an issue isolated to this network segment.

 

I haven't got any L3 rules/configuration set up, not sure if that's affecting things.

I inherited the site, but the switch does seem fairly vanilla in terms of other configuration.

 

Any guidance on this would be awesome.

 

Thanks!

  @WellConn 

what's the router? is there an acl to block the talk? 

what you have on port 1-22 are getting 10.0.0.1/24 while  your vlan 30 can ping 10.0.0.1/24?

as for the switch, it is forwarding the traffic by mac address table. vlan you create is not 802.1q vlan but vlan interface.

  @Tedd404 

Thanks for the response!

 

Router is a watchguard firewall, no acl's.

If it was blocking the talk wouldn't it block all communication(iPad to Printer) not just iPad to iPad?

 

1 to 22 is getting a 192.168.9.x/24

10.0.0.x/24 can ping forward and back without issue.

 

In L3 Interface, I have added the Interface and it's now showing as UP.

 

Is there a different way I need to assign the ports when doing VLAN's by Interface vs 802.1q??

 

Please let me know.

 

Thanks!
