Proxmox Web Interface Not Accessible When Shaw Modem is in Bridge Mode

@Papa_Dragon It seems as if you're not following instructions given. Also, you need to read up on pfSense as much as possible. A statefull firewall, such as pfSense, nothing can enter the WAN unless the request comes from LAN; so, putting these rules on WAN is pointless...they're not doing anything...see the circle on the pic below. You were told to leave WAN with the default rule it had OR read Netgate document on WAN.

What's this 10.0...that's not a complete IP address...please disclose the full address. If you look at the circle, LAN.net tried to contact this 10.0 address BUT the address is not responding. Now, look at your DNS below the circle...you see that your DNS is working...

@NollipfSense

i understand the confusion. And i apologize if I am making this difficult. in my defense i had no idea what pfsense was... until like 2 months ago. this is a new hobby for me, with a huge learning curve and i am excited to enter the world but didn't realize how much work it would be, but i can assure you that i am willing to learn. i am trying my best to follow your instructions, but i mostly go off of your pictures to understand what to do. i wouldn't be on this forum if i knew what i was doing, but sense its new to me I am reaching out and asking for help because i have a very small percentage on what i am doing. So again i am sorry if this is frustrating.

for the wan i have portforward that i would not like to disclose, as it may or may not be exposed to the world and a potential security risk. all i well say is that its a game server that i have set up with my buddies. it appears that its doing nothing but infact it is. Also for the LAN it was a complete address. i just photo shopped it to block out any potential security risks.

Good, we all had been there.

Learn to use firewall alias...they're awesome firewall tools so you can show without disclosure. Also, ping LAN.net from 10.0.0.15...make sure the protocol is IPv4 TCP/UDP so we know that also works

@NollipfSense

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.

@NollipfSense ![Screenshot (23).png]
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...!

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.

@NollipfSense okay well its a bit confusing so if you wouldn't mind giving me a breakdown on what needs to get done i would appreciate it! i would like a breakdown step by step please.![image-370.png.webp](Invalid file type.

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 · Jun 9, 2023, 1:46 AM

@NollipfSense this is actually the physical set up

Papa_Dragon · Jun 9, 2023, 6:38 AM

@Papa_Dragon okay to clarify

swap promox to pfsense LAN gateway?
swap dns using nano /etc/resolv.conf (done)
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

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

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