Access switch from VPN

mgatti0129
Level 1
Level 1

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?

Regards,

Paul



****Please rate useful posts****

HTH Paul ****Please rate useful posts****

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
