Inter vlan routing and static vs dhcp

[Djsky123]

Hi, I have a strange issue.

MX85 as a security appliance, also provides dhcp on a few vlans.

my main laptop on vlan 1 can generally see devices on other vlans.

I’ve plugged a smart device into a switch port that has a pvid of vlan 2.

if the device is set to DHCP I can see the webpage of the device from my laptop on vlan 1 without issue.

if I set the device to a static ip with exactly the same address, subnet, gateway, dns - I can PING the device from the laptop, but can’t access the devices webpage at the same address.

any ideas?

hello,

Is the MX the DHCP server for vlan 2 as well? What kind of switch are you using? Any other devices performing layer 3 in the environment besides the MX? What if you plug the smart device straight into the MX and bypass the switch?

[Djsky123]

Yes, it’s running dhcp for all vlans.

they’re Engenius Switches, but no layer 3 functions.

not on site for a few weeks, so can’t do any physical changes to test.

Why don't you just make a DHCP reservation for this device instead of setting a static IP?

That’s fine but I’d like to understand where the problem lies.

Are you sure you have configured the correct Gateway?
