[SOLVED] Can not ping outside of network with VE Host

[bencanfield]

Hi, this is my first time ever posting on a forum and I am new to Proxmox. I am running into an issue where I can ping anything within my network but can not get passed my gateway when trying to ping something like "google.com". However, with VM's I am able to ping outside of the network. I have followed what I belived to be every tutorial I could find to troubleshoot but I have been unable to find a solution.

cat etc/hosts
127.0.0.1 localhost.localdomain localhost
192.168.1.167 pve1.local pve1

# The following lines are desirable for IPv6 capable hosts

::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

auto lo
iface lo inet loopback

iface enp0s31f6 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.1.167/24
gateway 192.168.1.1
bridge-ports enp0s31f6
bridge-stp off
bridge-fd 0

iface wlp1s0 inet manual

source /etc/network/interfaces.d/*

ip route

tcpdump: listening on enp0s31f6, link-type EN10MB (Ethernet), snapshot length 262144 bytes
^C

0 packets dropped by kernel


All of this makes me believe it is a router issue. That being said, I do not have much experience with networking and I am unsure what would need to be fixed.

Any tips would be greatly appreciated,
Ben

Following this traceroute: I'd suggest that your Router could not communicate with it's default gateway
But it probably worked earlyer and the DNS resolution of google.com is still chached.

To debug further:
- Can you Ping from the Router in direction Internet?
- Able to ping your Gateway from Proxmox Shell?
- Have you multiple Subnets on the router and you must create the Firewall ruleset to allow Internet access?
- Do you have any MASQUERADING (Source NAT) missed to configure?

If you could make a short draw or scetch of your network including the subnet infos I could probably see more...

For whatever reason my firewall was blocking outbound traffic for my server. Was able to override it. Solution solved
