Newbie. Virtual IP question Device another subnet

[potes]

Hi,

Can anybody help this newbie solving this issue.

I have a device (DEv1) in a VLAN subnet (subnet1). I need that device to have also an IP in another VLAN subnet (subnet2) to be discoverable. As the VLAN are assigned to different interfaces I cannot attach another network card to the Dev1 to connect to subnet2.

Can I use a Virtual IP on subnet2 that will forward all request to the DEv1 IP on subnet1?. How can I do it?

I have been looking on internet and in the forums but I cannot find anything, everything I found about Virtual IP deal with the WAN interfaces.

Thanks

When you are using VLANs, why not assign the VLAN directly to that Intetface?

I also need the DEv1 connected to subnet1.

Now I have  VLAN50 (subnet1) on lagg1 interface and VLAN22 (subnet2) on lagg0 interface. Can I attach a VLAN22 to lagg0 and lagg1? That way I will be able to add another network card to Dev1 (is a LXC container) attached to subnet2.

You can add VLAN manually on Linux machine - here are more details https://www.linuxtechi.com/vlan-tagged-nic-ethernet-card-centos-rhel-servers/

But routing from newly created VLAN is a different ball game. If Dev1 is connected to a managed switch that allows more than one VLAN tagging per port then it might be a breeze otherwise it will get complicated.
