[SOLVED] Help - Access Management Interface Post-Installation

[jcate207]

Hi, I'm a beginner to networking and home lab stuff so I apologize in advance if this is duplicate post or whatever. I've done my research but I'm not sure how to troubleshoot the issue assessing the management interface post-installation. I'll try to distill some of the things I've tried and
DHCP IP Pool: 192.168.0.100 - 192.168.0.249 (ensured the server Ip avoided these ip addresses)

output: cat /etc/network/interfaces

iface lo inet loopback

iface eno1 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.100.2/24
        gateway 192.168.0.1
        bridge-ports eno1
        bridge-stp off
        bridge-fd 0

iface wlp9s0 inet manual

output: cat /etc/network/interfaces

127.0.0.1 localhost.localdomain localhost
192.168.100.2 pve.home pve

# The following lines are desirable for IPv6 capable hosts

::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
fe00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

---

abridged output: ip a
2: eno1 is up
4: vmbr0: is up
inet 192.168.100.2/24

---

The output on host server(server running proxmox) for "curl -k https://192.168.100.2:8006" looks to show the HTML for the Management Interface.

---

Issue: Timeout accessing Management Interface from another PC web browser. Not sure what's next to investigate.

Thanks in advance for the help.

Hi,

Does your router (192.168.0.1) do routing between 192.168.0.1/24 and 192.168.100.1/24 ?

If not, why put proxmox server on 192.168.100.2 ?

Best regards,

As far as I understand no. It uses the following IPs for DHCP



Not sure what the "/24" part of "192.168.0.1/24" does, but that was the default used by the Installer.

Does the static IP assigned to Proxmox need to be assigned to one of the IPs used by available for use by the DHCP pool?

As far as I understand no. It uses the following IPs for DHCP

If your router doesn't route between these two networks, you must give to the PVE an IP address from the same network that your PC has.

The netmask /24 means IP addresses from x.y.z.0 to x.y.z.255

Does the static IP assigned to Proxmox need to be assigned to one of the IPs used by available for use by the DHCP pool?

The opposite. NOT from the DHCP pool but from the same network (and of course the address must be free, not used by any other device). Good luck!

No, but you promox need to be in the same subnet if you don't have routing between 2 subnet.

To put it more simply, you proxmox should have an IP between 192.168.0.2 and 192.168.0.99 assuming you don't have other devices in static IP in this range.

The way you had configured your network is to join your proxmox from your PC, your PC (in the 192.168.0.XXX subnet) need to ask 192.168.0.1 (your router) to join 192.168.100.2 (your promox), but your router don't know anything (as I understand) about the 192.168.100.xxx subnet, so it's normal that it doesn't work.

Not : it's a simple explanation without too much technical details so yes I know technically this explanation is not true, but I assume you have restricted knowledge of how a network works technically.

Best regards,

Thanks @janus57 and @Onslow. I assigned it to 192.168.0.6 and that worked.
