  • 1.  Ex4650 routing to internet from all vlans

    Posted 06-18-2025 11:20

    Hi all

    I've got an ex4650 that I've configured one interface with the IP of our upstream Cisco router and routing options next hop to that IP's gateway.

    From the switch I can now ping 8.8.8.8 as well as the gateway of that public IP configured in the next hop.

    my problem is I can't ping either from any other interface on the switch.  I can ping the IP of the interface I configured and other gateways and IP devices connect to the switch.

    I just can't "get out" from any of them.  I know this has to be something so small that I'm just missing it.

    Thanks in advance!

    Basically if I "ping interface [interface] [IP] where IP equals the configured gateway from any other interface except the one configured  I get "no route to host".

    The problem seems to be your Cisco router.  Make sure it is configured to source NAT from these other internal nets and that it has a route back to these internal nets.
