I had a working proxmox setup in my lab, and then I moved it to be in production. This is the intended setup.

proxmox pve ( I call host) just manages the vm's. I have 2 vm's. vm1 will be a debian gw and firewall, and also run samba for the internal lan.
I am not sure what I have "pooched", however, I am able to access the pve and vm1 via ssh , ( as I have another gw device on the network)
the pve network/interfaces show me this.

so basically 2 bridges, one bridge to eno1 and the other bridge to eno2

if I run "nmap -p 8006 vmbr0 or vmbr1" they both show the same that the web gui is running.

if run nmap from outside the host ( on the internal lan) on either of the ip's, ( 192.168.1.10 or 192.168.1.12) I get the following, and am not able to connect to the management gui.

on the host eno1 is connected to the ISP gw ( wan) and eno2 is connected to the lan switch.

any ideas, I think I have over thought this and am just confused.

thank you

So you have two NICs in the same subnet? There's probably already your problem. Just don't.

actually no, one nic is connected to the ISP/internet/wan and the other is connected to the internal lan
 
sigh, humbled again. as I look closer at this, my ignorance is displayed. thank you for your time.
