Basic PVE 6.2 setup - guest have no internet accress

[rykr]

I'm read the docs regarding bridged mode. My interfaces file is essentially right from install.

auto lo
iface lo inet loopback
iface enp4s0 inet manual
auto vmbr0
iface vmbr0 inet static
address 192.168.1.130/24
gateway 192.168.1.1
bridge_maxwait 10
bridge-ports enp4s0
bridge-stp off
bridge-fd 0

network on the host works well. Guest boots up nicely and can ping the host but has no internet access at all.

Any idea what I'm doing wrong?

ip link shows this:

Anyone have any ideas on this? This seems so basic I have to believe it's something simple.

can you send you guest vm network configuration ?

 

[rykr]

ok. It's pretty basic. Machine has a single nic. Private server in my home. out of the box install. Had to add bridge_maxwait 10 to my /etc/network/interfaces file in order to get the network to work at boot.

Using bridge of vmbr0 (the one the installer setup).
no vlan tag
model is E1000
firewall is disabled.
all other options are default.

the vm can ping the host and, after disabling the Windows firewall on the guest, the host can ping the guest. However, the guest has zero internet connectivity. My home router sees the vm and lists it's ip as 192.168.1.160 and the windows vm shows it's ip as 192.168.1.160 but it lists "preferred" by it. Not sure if that means it asked for 160 but not response back.

Windows is the guest and is set to use DHCP for everything. This is a physical hard disk. I can boot the windows disk natively or boot it under Proxmox.

I tried installing a different os under a Proxmox vm and it didn't have internet either so I think it's like packet fwding two the gateway is not happening

can you ping your home router from your vm ?

if yes, and that you don't have internet access, something is wrong on the router side.

No. I can ping host only from vm

No. I can ping host only from vm

I’m having the exact same issue with an identical setup. I also have an i225-v NIC (I just posted in another thread of yours as well). Any chance that could be related?

Does your VM have the correct gateway IP set?

 

[rykr]

Does your VM have the correct gateway IP set?

Mine does. Gateway of 192.168.1.1 in my case

 

[zaptrem]

Does your VM have the correct gateway IP set?

So does mine, I double checked by comparing to other PCs on the network. The VM seems to successfully acquire a new local IP and the network’s suggested DNS servers despite me not explicitly setting them (I didn’t even set those DNS servers on the host). Does this mean it was able to communicate with the DHCP server, then lost that ability after setting its IP? Or did it grab this info from the host somehow?

 

[bobmc]

so what does tracert 8.8.8.8 from the VM do?
