Use additional address as VLAN gateway

Hello Josh Marchant,

Thank you for reaching out to the community, You must have a VLAN tagging switch hooked up to the UTM. At a minimum, the port connecting the UTM to the switch must be configured as a trunk port, and it must be a TAGGED member of each VLAN that you want the UTM to use.

Hi Vivek,

I do have a VLAN tagging switch hooked up to the UTM via a trunk port, however I'm still not clear on how to configure which additional IP address to use as a gateway,

Thanks

So you have created an Alias/Additional IP under Interfaces & Routing > Interfaces > Additional Addresses > for desired "On interface" And now you want to use that Alias/Additional IP as the the gateway for the Ethernet VLAN under  Interfaces & Routing > Interfaces > new > type Ethernet VLAN, is that correct ? 

That is correct yes

In that case , while create a VLAN:

You have an option to to enable "IPv4 Default GW"  their you can provide the gateway IP.

I did try that, but when using that it forces the VLAN to be added to uplink balancing which isn't what I want.

In that case Josh Marchant,

Did you check the option mentioned by BAlfson

Unfortunately we don't use web filtering so our license does not include it. Is there no way to do this with static routes?

Adding a manual static may help but that wouldn't be reboot persistent...
