Hello everyone,
First and foremost, I apologize for my lack of knowledge in the field, as I am a relatively new student in the networking world with limited experience.
Currently, I am working on a school project in which I need to provide private and internet services to three different VLANs.
The classroom computers are configured to operate on a switch with the network 192.168.36.0/24.
My router is connected to the classroom switch to ensure that the class computers can access the settings of the devices I am working with.
The connection between my router and the switch is made through optical fiber.
Based on this setup, I have three VLANs that are working to provide Public services, private services, and network resources.
- VLAN 10: Private Services
- VLAN 20: Public Services
- VLAN 30: Network Administration
The issue is that my router can ping 8.8.8.8, but my switch cannot.
Additionally, I have tried to configure DHCPv4 for VLAN 1 networks, but it is not functioning.
I can access the switch and router through PuTTY:
- Router: 192.168.36.17
- Switch: 10.10.37.254
Honestly, I would appreciate it if someone could review the configuration of both devices, identify errors (which I'm sure there are many), and assist me in correcting them with the necessary commands.
Thank you very much to anyone who has taken the time to read this.
