@tolx_ Welcome to the VHT forums! Great to have you here in the community. This should be doable using VLANs. With VLANs, you can carve up an existing single physical adapter so that it appears like multiple adapters that can be used for various purposes. Below is a crude drawing of what you could do:
With VLANs the number of physical uplinks is no longer limiting since you can present virtual interfaces to VMs, devices, etc. Let me know if this makes since or helps?

thank you, i have a netgear gs308e switch and i am trying to see how to add two vlans in one port and its not working

@tolx_ it looks like the gs308e is VLAN capable just from a few searches I have done. Saw here that for most, you will find what you need under VLAN -> 802.1Q -> Advanced only. You will want to add VLAN tags to your ports where you uplink your second NIC from your Proxmox server with the VLANs you choose to use for WAN and LAN/other. Let me know if you see the VLAN, 802.1q, Advanced only menu in there.

so i did all that you said and maybe i made a mistake in one of the steps
i went to my Netgear switch and enabled vlan with 802.1q and for the port membership the first port is what is connected to my router and also the second
i also played around with the pvid and made it this
in my proxmox server, this was the setting i used for enabling the vlans
i tried pinging my host network and its not still working could you pls look at my configuration and let me know where i went wrong

@tolx_ Just at a glance, there may be a problem with tagged vs untagged traffic on your switch. Can you also post your configuration shown in /etc/network/interfaces on your Proxmox server? That will help give some more detail on what is being sent exactly on the Proxmox side.

@tolx_ Just looking at your screenshot. So the 192.168.20.21 IP address is your management IP that you are attempting to connect to for management right? Also, what VLAN are you expecting this IP to reside on and which switch port are you connecting it to?
