Hi @Dimitris_T 

Thanks for posting in our business forum.

Can you show me your VLAN config? Network diagram as well? Please make the VLAN on the diagram which would be great.

Management VLAN? Is the VLAN VLAN interface? Is that what you are referring to in this context?

So, as for now, I cannot judge the issue yet. Here are some unclear things:

1. If your devices can get Internet from VLAN10, which means it should be able to access the Internet. So, forget about the ping 8.8.8.8. Will you be able to ping the VLAN 10 gateway IP?

If good, that means PC2's firewall is blocking the previous pings. Fix the firewall.

2. VLAN1, all other devices in the VLAN1 can access the Internet? If yes, they can ping 8.8.8.8 okay?

Static Routing can be changed to the next hop of your gateway IP. Try if this works.

Let me know your results.

Hi Clive_A

 

The Network Diagram is:

 

Router : 192.168.0.1 ---> Firewall: 192.168.0.250 ---> Switch TPLink: 192.168.0.150 ---> and the Pcs that is on that Switch.

 

Vlan (1) : 192.168.0.0 :  is the default VLan.

Vlan (10): 192.168.10.0 :  I create it for some PCs.

 

Here some images from TPLink.

VLans:

 

 

 

 

When I connect a PC to Port 1-4 (with VLan (1) ) I have Internet, I ping 8.8.8.8, All Switches,and all other Device on the Company.

When I connect the PC to Port for ex. 5 (with VLan (10)) I have Internet, I can ping other devices on any VLan... for example Gateway, Firewall, Printers, PCs, Switches...

BUT I CANNOT ping the Switch TPLink that is connected... Only the TPLink I CANNOT ping...

 

I have change the route... and still cannot ping the Switch

 

Inside The Switch from Network Diagnostics I cannot ping 8.8.8.8 and others devices that are not belongs to VLan1.

Ping Result 8.8.8.8:

 

 

Ping Result to PC with VLan 10:

 

Ping Result to my PC with VLan 1:

 

 

You should check this guide out.

I start to think this is a problem with your static routing and multi-net NAT. There does not look like a problem with the switch.
