Hi @xHAWAKx 

Thanks for posting in our business forum.

What's the PVID on #23?

What does the routing table look like?

What would be the gateway IP address?

Can you ping another device from the switch but not be able to ping back to the switch?

Hello  @Clive_A,

 

• PVID for port 23 is set as 1

 

 

 

 

 

• Routing table in the switch is set up as in picture below 

 

 

 

• The gateway IP is 10.99.10.1

 

• From the switch I can only ping the other switch (10.99.10.20) I can't even ping PC 5

 

 

 

 

Any other client from the switch go in timeout.

 

 

 

The only client that can ping the switches is PC 5

 

 

I commited some mistakes in the net-diagram please check the new diagram below (I apologise for this)

 

 

 

 

Basically I only able to connect to GUI of the swtich because of the interface n.3 with the IP 10.99.10.6 (this is a work around and I do not want it like that)

 

 

Thank you in advance for your help

 

Add a routing.

0.0.0.0, next hop 10.99.10.10. If this helps.

10.99.10.6 is not pingable but 10.5 is, that's a firewall issue on the computer.

Dual NICs mean you have two pages for network firewalls.

I am not worried about this PC as 10.5 is pingable.
