Aruba 2930F inter VLAN routing

Goals :

  1. Separate LAN into 3 different VLAN
  2. Granting access to the Internet to those 3 VLAN through VLAN 1000

Issue : Unable to access the Internet from a PC connected to any of those VLAN : 100,110,120. I attached my configuration. I think I missed something important. Any help much appreciated.

 

Test environment

Re: Aruba 2930F inter VLAN routing

Can you try to add to the switch an 'ip route 0.0.0.0 0.0.0.0 192.168.22.1'. Check this post to see that ip default-gateway is just for the switch itself in 'no ip routing' mode.

 

Also if that doesn't work, check on your router if it will perform NAT for all traffic coming into the LAN interface, or just for the subnet on that interface. Some routers only NAT or allow traffic from the subnet, not if it is routed like in your case.
