No Network Access After Install

Hello,
I just installed Proxmox and cannot access the network. I can ping my interface but cannot ping the gateway. I cannot access the web interface either.

I also noticed there is no eth0 listed when checking ifconfig.

/proc/net/dev does not show eth0.

/etc/udev/rules.d/70-persistent-net.rules does not exist

Network configuration
IP: 192.168.1.253
Netmask: 255.255.255.0
Gateway: 192.168.1.254

Thoughts? What should I try or do you need me to provide?

I found this link but it just kind of dead ends..
