Hello everyone.

Ugh... I'm afraid to even ask the question... Just to be fair - I am an amateur - I don't even know what I don't know...

Ok so I am setting up proxmox but its "complicated".

- Normally proxmox runs with LAN device as a main network (internet) interface - in my case its wireless.

- Wireless network runs as 192.168.1.10 wlp3s0.
- There is a LAN interface present enp0s25 its set 192.168.0.1
- There is a vmbr0 which is also bridged with wlp3s0 device running with 192.168.2.10

- I have post-up rules in my /etc/network/interfaces that are setting up the masquerading and enable ip forwarding - the rules look like this

Code: 
post-up   echo 1 > /proc/sys/net/ipv4/ip_forward
post-up   iptables -t nat -A POSTROUTING -s '192.168.0.0/24' -o wlp3s0 -j MASQUERADE
post-up   iptables -t nat -A POSTROUTING -s '192.168.2.0/24' -o wlp3s0 -j MASQUERADE

Thanks to those I have internet on both LAN and VM machines. Before I added those - I had neither.

Well... the devices from the enp0s25 side can talk to the vmbr0 devices so for example if I ssh from 192.168.0.104 to 192.168.2.12 vm - it works. I can also connect to the wlp3s0 proxmox ssh on 192.168.1.10

Wireless devices on my network running 192.168.1.x IP can access wlp3s0 ssh on 192.168.1.10 - that's the proxmox server BUT they cannot access any of the vmbr0 devices - as in the vms

So for example laptop connected wirelessly as 192.168.1.40 can ssh to the wlp3s0 192.168.1.10 (proxmox server) but it cannot ssh to the 192.168.2.12 - vm.
In the same time desktop connected via cable as 192.168.0.104 can ssh to both of the above mentioned ssh servers.

I am assuming that I need to add routing rule so that the wlp3s0 192.168.1.10 device lets the requests from 192.168.1.x devices to the vmbr0 192.168.2.x devices correct?

I am not even sure if its my proxmox routing that's the issue or my modem / router from the ISP that's blocking the connections between the sub-networks

What I would like to achieve is have proxmox access internet via wlan and then spread that internet to the virtual machines using vmbr0 device and to the LAN machines on enp0s25 - so that all the networks 192.168.0.x 192.168.1.x and 192.168.2.x are talking to each other.

Before you ask me - its a home server, not work / school related. I am not looking for someone to do my homework, I am trying to learn / get it going for home purposes

Thanks in advance for any help provided.

Kind regards.

Andrzej

Hi all

Just to add:

1604854141056.png

My router cannot ping the vmbr0 device either. I think there would be two reasons. Either the router is not great - wouldn't surprised me - and it basically cannot route the packets properly OR and I am hoping this is the case - the wlp3s0 (proxmox wireless device) is not routing packets properly - this would possibly be an easy fix for someone who know what they are doing (diagnostics / iptablesfoo).

Regards.

Andrzej
 
I ran this on the proxmox machine

Code: 
iptables -A FORWARD -i wlp3s0 -o vmbr0 -s 192.168.1.0/24 -d 192.168.2.0/24 -j ACCEPT

iptables -A FORWARD -i wlp3s0 -o vmbr0 -s 192.168.1.10 -d 192.168.2.0/24 -j ACCEPT
iptables -A FORWARD -i vmbr0 -o wlp3s0 -s 192.168.2.0/24 -d 192.168.1.10 -j ACCEPT
iptables -t nat -A POSTROUTING -s 192.168.2.0/24 -o wlp3s0 -j SNAT --to 192.168.1.1

Didn't help... Any takers?

you can't add ip address on a interface enslave in in bridge. It's curious than dhcp is able to give it an ip, but I don't think it's work.

about enp0s25, I don't known what you're trying to dot, but it's not a bridge, so you can't add bridge options to this interfaces.

why don't you do a simple

Code: 
auto vmbr0
iface vmbr0 inet static
        address  192.168.2.10
        netmask  255.255.255.0
        bridge-ports wlp3s0 enp0s25
        bridge-stp off
        bridge-fd 0

or with dhcp


Code: 
auto vmbr0
iface vmbr0 inet dhcp
        bridge-ports wlp3s0 enp0s25
        bridge-stp off
        bridge-fd 0

Hi

For some reason your method did not work. After reboot I've had no internet on the enp0s25 device. Possibly on vmbr0 too.

My config at the moment is insane but it works and I've figured out my problem with port forwarding. Well its a workaround but it works so...

Now I am having trouble with multicast but that's a story for another place and time.

Hi

For some reason your method did not work. After reboot I've had no internet on the enp0s25 device. Possibly on vmbr0 too.

My config at the moment is insane but it works and I've figured out my problem with port forwarding. Well its a workaround but it works so...

Code: 
grep -v '#' /etc/network/interfaces

Code: 
auto lo
iface lo inet loopback


allow-hotplug wlp3s0
iface wlp3s0 inet dhcp
        wpa-ssid redacted
        wpa-psk redacted


auto vmbr0
iface vmbr0 inet static
        address  192.168.2.10
        netmask  255.255.255.0
        bridge-ports wlp3s0
        bridge-stp off
        bridge-fd 0


allow-hotplug enp0s25
iface enp0s25 inet static
        address  192.168.0.1
        netmask  255.255.255.0
        bridge-ports wlp3s0
        bridge-stp off
        bridge-fd 0
