Conformance test runner cannot connect to NKG Pods

[kate-osborn]

Describe the bug
The conformance tests send traffic to the IPs of the NKG Pod for the corresponding Gateway. However, all tests that send traffic are failing with:

http.go:217: Request failed, not ready yet: Get "http://<POD-IP>": dial tcp <POD-IP>80: i/o timeout (after 26µs)

and

http.go:217: Request failed, not ready yet: Get "http://<POD-IP>/": context deadline exceeded (after 22.3µs)

To Reproduce
Steps to reproduce the behavior:

1. Run conformance tests. If you don't want to run the whole suite, run HTTPExactPathMatching test. This will reproduce the error.

Expected behavior
Test runner should be able to connect to the NKG Pod and get a response back from nginx.

Your environment

• NKG edge

Additional context
This error occurs in 16 tests so it is critical that we fix this bug.
