<p>If I have two pods running on different namespaces, and there is netpol already setup and cannot be modified, how would I approach the POD to POD communication making the ingress and egress possible again without modifying the existing object?</p>

<p>The netpolicy that is already there probably does a general ingres / egress block. If you add another policy that specifically allows the POD to POD you need then it will, in this case override the general policy. See <a href="https://serverfault.com/questions/951958">https://serverfault.com/questions/951958</a></p>

<p>Yes, you can add another network policy according to your needs and everything should work.  It doesn't matter in which order you apply your rules.</p>
