Issue accessing Proxmox server web interface after setting up pfSense

[Papa_Dragon]

Hello,

I'm encountering an issue with accessing the web interface of my Proxmox server.

Here's my setup:

I have a Dell R710 server running the latest version of Proxmox, and I recently installed pfSense as a VM on it. Currently, pfSense is the only VM running, and it is connected to the LAN.


My networking setup is as follows:

My ISP connection goes to the WAN interface on my server, and from there, it connects to a network switch. The LAN connection from the switch is connected to the server's built-in 4-port NIC.

Initially, I tried configuring pfSense to use the PCIe NIC, but it didn't detect the hardware, so I ended up reinstalling Proxmox a few times. Finally, I created two bridges to resolve the issue. The first bridge, vmbr0, is connected to the PCIe NIC, and the second bridge, vmbr1, is connected to the eno1 interface, which was originally providing internet to the server.

Now, I'm facing another problem. Although pfSense is running and has internet access, I can't access the web interface of my Proxmox server. I have an idea of what the Proxmox server's IP address might be, but I suspect that the issue might be related to DNS.

I have tried changing the DNS settings, but I don't get any internet access as a result. I also attempted to edit the "/etc/network/interfaces" file using the "cmd" command, but I didn't get any internet access after making the changes. For now, I have set the DNS to whatever gives me internet access.

When I try to ping "google.com" directly on the server (not through SSH), I don't get a response. However, when I ping "<my_ip_address>", it works fine. This leads me to suspect that there might be a DNS or firewall-related issue that is preventing the connection.

The CMD I have used to troubleshoot is as follows

nano /etc/resolv.conf which currently is set up to this

comein es.shawcable,net
search eg.shawcable.,net
nameserver 64.59.135.147
nameserver 64.59.120.113


Nano /etc/network/interfaces

auto 1o
iface lo inet loopback
iface eno1 inet manual
iface eno2 inet manual
iface eno3 inet manual
iface eno4 inet manual
iface enp6sofo inet manual

I iface enp6sof1 inet manual
auto vmbro

iface vmbro inet static
address 10.0.0.15/24
bridge-ports enpesofo
bridge-stp off
bridge-fd
sauto vmbr1

iface vmbr1 inet manual
br idge-ports eno1
bridge-stp off
bridge-fd 0

-chmod 644 /etc/resolv.conf
-ip route add default via 192.168.1.1 dev vmbr0
-unlink /etc/resolv.conf

I would appreciate any additional troubleshooting steps or guidance to help resolve this issue. Thank you in advance

i think it should be domain? commas are not legal characters for domain name.

iface eno1 inet manual
iface eno2 inet manual
iface eno3 inet manual
iface eno4 inet manual
iface enp6sofo inet manual

these all look like letter o (oscar), it should be 0 (digit)
same thing for the rest

address 10.0.0.15/24

-ip route add default via 192.168.1.1 dev vmbr0

your gw should be on the same subnet as your IP, its not.

I suggest you go over the configuration files with a fine tooth comb

good luck

Sorry, they were miss typed. Here are the actual pictures.
Also ip route CMD was just something I tried for troubleshooting as well as the other cmds
