Hello,
I have a 2960S Catalyst switch in my LAN, with the firewall and the servers in the same VLAN (vlan 3).
All the servers and the firewall are in the vlan 3 are in the "192.168.19.0/24" subnet, the firewall has the IP "192.168.19.1".
I can land on the firewall with a VPN (192.168.130.0/24) which has a complete view on the subnet 19/24.
I can access, manage and get SNMP information of the Catalyst from the servers but I can't do the same from the VPN.
Is there some feature I need to enable on the switch in order to allow 192.168.130.0/24 to access it?
Thank you in advance
Maurizio

Hi Maurizio,
Can you ping anything on the 192.168.19.0/24 network when you are on the VPN?
Kind regards,
Paul

Hi Paul,
thank you for your reply.
Yes, I can ping everyhost on the 192.168.19.0/24 network (1) but the swtitch.
From the switch itself I obviously can ping everything in the same LAN but the default gateway 192.168.19.1 and the network on the other side of the VPN (192.168.21.0/24).
From any host in the .19.0/24 network I can ping the default gw and every host in the 21.0/24 subnet.
Here (2) the running-config of the switch.

Hi Maurizio,
Which port on the switch is used to uplink to the firewall?

Paul

Hi Paul,
th port dedicated to the firewall is "interface GigabitEthernet0/3".
GigabitEthernet0/1 is used to uplink to the ISP infrastructure.
The GigabitEthernet0/2 is used as a link between the switch (vlan 2) and the firewall.
interface GigabitEthernet0/1
