I left the default route on the internal interface, eth0. I also left the dns pointing to the internal as well. I was able to ping around.

we need to look at how you want the pod to connect/route to what subnets internally(eth0) vs externally(net1).

root@nginx:/# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         10.42.0.100     0.0.0.0         UG    0      0        0 eth0
10.42.0.100     0.0.0.0         255.255.255.255 UH    0      0        0 eth0

Can it be assumed that 10...* is all interal to the cluster? Or are there vlans on your network that have that subnet. You might be able to say default is net1 and then make sure you have DNS and other routes just for the 10.x.x.x

Cool. I am fairly certain you don't need

        "routes": [
          { "dst": "192.168.0.0/16", "gw": "192.168.20.1" }
        ],
      "gateway": "192.168.20.1"

in the NetworkAttachmentDefinition

apiVersion: "k8s.cni.cncf.io/v1"
kind: NetworkAttachmentDefinition

I will test without but I think I need both in the NAD. I've added mac because I don't want a random mac every time i started up, dhcp gets messy. Yeah, I could remove the namespace but I always declare it, even it is is default.

I do need routes otherwise I can't reach it from the outside. I can remove gateway.

    {
      "cniVersion": "0.3.1",
      "type": "ipvlan",
      "master": "eth1",
      "ipam": {
        "type": "static",
        "routes": [
          { "dst": "192.168.0.0/16", "gw": "192.168.20.1" }
        ]
      }
    }
