      so i tired to ping on my server i only have access to it due to a mouse and keyboard, and a monitor, but i cant ssh in. i tired ping LAN.net (from my server aka 10.0.0.15) and i got this as a result. temporary failure in name resolution

      which one should be the TCP/UDP?

        Select both...port 8006 is UDP and update Proxmox will use TCP.

          is this what you meant? also sorry for the late reply ( i guess early lol for me at least). would adding another LAN for my eno1 work? like if i went back and accessed my proxmox and added the vmbr0(aka eno1)? would disabling the proxmox firewall work? I'm just trying to figure it out

          also this is Photoshopped!! dont worry its not blank...!Screenshot (23).png

          edit when i was assigning, the gateway i used the WAN gateway. but I've noticed that any time i connect a device to my LAN it gets a different gateway. so should i have put the LAN gateway or the WAN gateway??

            Only your LAN has a gateway...WAN just connects you to the Internet...your network is LAN.

            That's because you still have it the same way in your original post despite several instruction. Maybe, that's why you have this, see below. Since you have port forwarded, that suggest you have some server function other than Proxmox. So, that seems to suggest you're implementing a sophisticated network. That's fine however, you must know what you're doing. A network diagram would be best for us to see what you want to accomplish.

                You image is invalid file type for the forum. This primitive image is how I imagined your network...see below. In your ISP router mode, you have access to Proxmox while ISP router in bridge mode, you don't have access. The drawing should help you see why.

                This image below is what you were told to do and since your Dell has a four-port NIC, you have two for pfSense WAN and LAN, one for Proxmox, and the other you can use for your port forward. Does this helps?

                    @Papa_Dragon okay to clarify

                    1. swap promox to pfsense LAN gateway?

                    2. swap dns using nano /etc/resolv.conf (done)

                    3. change IPv4 tcp protocol to TCP/UDP?

                    i tried for the caveman drawing, sorry if its bad

                    this is the written version of what i have set up

                    1. internet>modem (in bridge mode) then from there 2 port NIC card (pfsense WAN and LAN interfaces) enp6s0f0 is made into WAN LAN is enp6s0f1 same NIC. there are 3 bridges in total and they go as follows:

                    vmbr0=eno1 (OG 4 port NIC)

                    vmbr1= enp6s0f0 (pcie NIC)

                    vmbr2= enp6s0f1 (pcie NIC

                    1. then on that same NIC, i have the LAN going off to my network switch. done.

                    2. the OG port for Proxmox is eno1 (not a "0" btw) that is hooked up to the network switch. done

                    so total 2 ethernet cords that are currently in my switch.

                    how i started/set up my VM on Proxmox

                    shaw modem is not in bridge mode

                    -named it pfSense

                    -chosen my hardware, ram, cpu cores, then on the networking page i said no, to default vmbr0 and opted to choose my own

                    • hit finish

                    • went over to hardware tab on VM and input vmbr1 (WAN) vmbr2(LAN) i even labeled them to not get things messed up

                    -made sure to hit boot at start

                    -booted it up

                    -then when it asked me for Vlan i said no

                    -then opted for me to choose an interface. WAN is as stated earlier same for LAN

                    • hit 2 on the pf boot menu

                    -set my own LAN ip address for pfSense

                    -proceeded to add a range for pfSense for my LAN

                    now what is on the switch (if its important) is as follows

                    • I have the pfsense LAN

                    • Proxmox eno1

                    • a wifi router to get wifi in my house

                    • smart lights

                    • PS5

                    what i have set up on my pfsense firewall

                    WAN

                    nothing

                    LAN

                    -i have a portforward for a game server for my friends and I

                    • i also have those "proxmox management"

                    • DNS

                    and other things in that photo

                    this is everything, i hope this clarifys things a little.

                    i apolozige that you need to repeat yourself its just a little over my head and the way i learn or at least know what to do is by a list of things like what i typed. so for example if i created a new LAN rule, it helps me understand if i know what to put. so it goes like this

                    interface: LAN

                    protocol: any

                    source : blah blah

                    and so on and so forth

                        @Papa_Dragon i got it up and running!!!!

                        So heres what I got done. I double-checked everything to make sure it was all up and running.

                        for anyone reading this issue

                        Here's a step-by-step walkthrough of the process, divided into sections:

                        Proxmox Setup:

                        Set up Linux bridges:

                        Create two Linux bridges: vmbr1 and vmbr2.
                        Assign enp6s0f0 to vmbr1 and enp6s0f1 to vmbr2.
                        Set up the VM:

                        Install the desired operating system in the VM.
                        During the VM creation process, choose "No network device" as the network configuration.
                        Configure VM settings:
                        Go to the VM's options and enable the "Start at boot" option.

                        pfSense Setup:

                        Set up WAN and LAN interfaces:

                        Configure the WAN interface of pfSense to connect to the modem in bridge mode.
                        Assign enp6s0f0 as the WAN interface.
                        Assign enp6s0f1 as the LAN interface.

                        Configure firewall rules:

                        Create appropriate firewall rules to allow desired traffic between WAN and LAN.

                        Network Setup:

                        Assign IP addresses:

                        Set the LAN IP range for pfSense
                        Set the gateway for vmbr0 (OG 4 port NIC) to LAN gateway make sure its the LAN

                        Set static IP for Proxmox:

                        Configure the Proxmox server with the static IP address 10.0.0.15 (or any available IP within the IP range you set).
                        Use a subnet mask of 255.255.255.0
                        and set the default gateway to the LAN.

                        Connect your computer to the LAN side of pfSense (aka Switch):

                        Pluged my computer into one of the ports on the network switch connected to the LAN side of pfSense.

                        Configure your computer's IP address:

                        this is where i had issues!!!!!!!!

                        i had to Set your computer's IP address to be within the same network range as the Proxmox server.
                        Assign an IP address of 10.0.0.xx
                        Use a subnet mask of 255.255.255.0
                        gateway: LAN of pfSense

                          I told you repeatedly, even drew an ugly looking diagram because I didn't want to spend valuable time with a network fancy diagram...wow! Glad you finally got it.
