[SOLVED] Can not ping gateway

[zmalqp]

Hello, today I've decide to update proxmox from 6.3 to 6.4 but i have discovered that one of my node can not access internet and can not ping the gateway.

Ping result:

ping 192.168.2.1
PING 192.168.2.1 (192.168.2.1) 56(84) bytes of data.
From 192.168.2.202 icmp_seq=1 Destination Host Unreachable
From 192.168.2.202 icmp_seq=2 Destination Host Unreachable
From 192.168.2.202 icmp_seq=3 Destination Host Unreachable

This is my interface configuration:

I have 2 gigabit network cards, the second one is not currently in use ( I plan to use it when i'm able to update):

08:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. Device 8161 (rev 15)
09:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 15)

Result of "cat /etc/network/interfaces"

# If you want to manage parts of the network configuration manually,

# PVE will preserve these directives, but will NOT read its network

The configuration is pretty much identical to the first node, but on that node everything works fine....

Could anyone help me understand what i'm doing wrong?

Thanks!

I've found the issue!

It was not my proxmox config but my router config, the DHCP was set in range 192.168.2.10 -> 192.168.2.200
My node ip vas 192.168.2.202


My router was cutting all connecton form ip that are outside the DHCP range, once i change that it all worked out!


Ps: I've also update proxmox from 6.3 to 6.4 without any issue
