Hi Steve

You seem to have plenty of server and switch ports available.

In your case I would suggest to use a separate cable for every VLAN defined on your switch.

Hi Stefan,

I had some hardware issues with my server and had to reinstall.  I saved the interfaces from what you had sent me last and I have a few more questions if you don't mind.

Below is the last configuration that you sent me.

What I would like to do is run a patch cord from my & to my switch that will do VLANs if this is the best we of doing it.

I want to be able to send to my VOIP Phones ( VLAN30 and Computer Network ( so that I can run a single cable to my VOIP phones and then from the VOIP Phone be able to use VLAN30 for VOIP and then use VLAN20 for the computer beside the VOIP Phone.

Would running a single cable from Computer Network NIC and a single cable from my VOIP NIC (which is my Proxmox) the best way of doing this or what would you suggest.

Thanks very much, I really appreciate your help.
