ER605 - No Internet Access for Switch and Router but End Devices Online.
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Hello,
I'm encountering a connectivity issue where neither my switch nor my router can access the internet directly. While my switch can successfully ping the router, showing that local network connectivity is intact, it cannot ping any external IP addresses on the web. My router can ping the web from its WAN interface but fails to do so from its LAN interface. Interestingly, all my end devices connected to the network do have internet access. Is this by design ?
This peculiar situation directly impacts my ability to set up NTP on my switch, as neither the switch nor the router seems to have proper internet access despite a clear route to the internet from the router's WAN side and functioning internet access for end devices.
Additionally, my network is configured with multiple VLANs, and I have not made any changes to the NAT settings on my router. My router uses the local NTP server address 0.0.0.0, ensuring its time is synchronized, but the switch, unable to use NTP on the web, it can only synchronize to the PC clock.
Given this scenario, I'm at a bit of a loss and could really use some advice or suggestions on how to tackle this issue, do I need a static route ? Has anyone experienced something similar or have any insights on what might be going wrong and how to fix it?
Any help would be greatly appreciated!
Hi @Pouet
Thanks for posting in our business forum.
My question will be is your router on default setup?
Second, what does your VLAN look like? Getting IP, so I assume you have set up the VLAN correctly. Consider multi-net NAT?
Use any search engine?
