Aruba 2930F inter VLAN routing

Jump to Best Answer
  • 1.  Aruba 2930F inter VLAN routing

    Posted May 29, 2019 01:57 AM

    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

    HP Aruba switch 2930F.png

    Router Edgerouter X configuration

    • LAN IP : 192.168.22.1/24
    • Static routes :

    configure

    set protocols static route 192.168.100.0/24 next-hop 192.168.22.253

    set protocols static route 192.168.110.0/24 next-hop 192.168.22.253

    set protocols static route 192.168.120.0/24 next-hop 192.168.22.253

    commit

    save

    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.

    hello,

     

    I have exactly the same problem with my Aruba 2930F in combination with my Netgear Nighthawk X4 router and I am thinking about buying a EdgeRouter X to solve this problem, did the issue with the inter VLAN routing not working ever get fixed ?
