dual-stack test failing

[manuelbuil]

Environmental Info:
K3s Version:

Vagrant env

Node(s) CPU architecture, OS, and Version:

Cluster Configuration:

3 servers

Describe the bug:

dualstack test is failing due to wrong addresses and lack of ipv6 default gateway

Steps To Reproduce:

• Installed K3s:

go test -v -timeout=10m tests/e2e/dualstack/dualstack_test.go

Expected behavior:

dualStack test working

Actual behavior:

dualStack test fails because:

• Node address check is wrong
• No gateway is defined for ipv6 and thus any connection to ipv6 services fails (e.g. when testing the clusterIP)
