[SOLVED] soyoustart, cannot ping guest from host

[dkent]

I setup Proxmox 6 on Soyoustart server and installed Centos 8 guest, but I cannot ping guest from host and vice versa. This server has only 1 public IP.

Could someone please help. Thanks.

Here are the configuration on host:

root@proxmox6:/etc/network# cat interfaces
auto lo
iface lo inet loopback

iface eno3 inet manual

auto vmbr0
iface vmbr0 inet dhcp
bridge-ports eno3
bridge-stp off
bridge-fd 0

-- route --
root@proxmox6:/etc/network# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 xxx.xxx.xxx.254 0.0.0.0 UG 0 0 0 vmbr0
xxx.xxx.xxx.0 0.0.0.0 255.255.255.0 U 0 0 0 vmbr0

hi,

i see you are using dhcp. how is that supposed to work at all? you should probably use a static address on your PVE host.

This server has only 1 public IP.

you should check natted network setup[0]

@Ogus, thanks for the response. Ya, dhcp was no good for internal network. I ended up creating vmbr1 with a static ip and then bridged that to the vms, which worked nicely.
