Can't access PVE web interface - will dynamic DHCP fix it?

[owlcapone]

Hello everyone,

This is my first post here so I hope to find the help I need. I initally wanted to install PVE on my Optiplex SFF as a home lab server project just to try things out. Also, My first VM I wanted to install was pfSense as I wanted it to replace my home router (which is a single deco XE75 Pro) , here is the sequence of what I did:

• I've installed proxmox on this optiplex and assigned the IP address 10.10.10.10/24 to it
• Installed pfSense VM and assigned vmbr0 bridge (Intel E1000) to WAN and that uses eth7 (which is the first of 4 ports NIC I have)
• I've assigned vmbr1 bridge as LAN (uses eth6 port)
• The static IP I assigned for pfSense LAN was 10.100.100.1/24 and activated DHCP server on it.
• I created another 2 bridges vmbr3 (eth5) and vmbr4 (eth4) on the remaining 2 ports of that NIC and called them LAN2 and LAN3 in pfSense.
• Now pfSense is working great and ready to work as my new home router.
• After that, I disconnected my original router (deco) and changed its mode from router to AP mode for WIFI access.
• Plugged in WAN in the first port (eth7) and deco in LAN (eth6) and yay everything is working.
• Now I am trying to access PVE web UI but unfortunately, I remembered too late that it was installed on the old router subnet and there is no way to access it other than through a monitor and keyboard that I have.

Now, All I can see is a bunch of errors on the monitor that say each port has entered block mode then forward state (I didn't really pay attention but it's definitely something wrong going on).



My question is:

Can I change the network settings of PVE through the terminal to access a dynamic IP address through DHCP (from pfSense I assume) and then assign a static IP address to it later on?

If that's not a valid solution, how do you think I can tackle this issue?

Side note: the other two ports LAN2 and LAN3 don't have any internet connection whatsoever despite the fact that their dhcp server is working and they assign IP addresses to any device connects to them without any issue. It's just no internet connection at all. I'd appreciate if someone can tell me why is this happening.

Hi,
pull off the router, that is supposed to be your gateway, was not a good idea, but nevertheless...
Access to the GUI is comming from the LAN side, so your 10.100.100.1 should be the website you shall use.
Doing changes on the CLI shall be possible, as the SSH server shall be avtivated by default on port 22. Giv it a try on your LAN IP address.

When you setup Proxmox Networking via the GUI, it internaly changes /etc/network/interfaces for you, which is Debians default networking config file. So if you have direct access to the machine, you can backup that file and make changes to it to restore remote access.

After changing settings in the file run "ifreload -a" to apply them.
