I'm 99.9% sure I already know the answer to this one, but is there any way to enable NAT-PMP (or uPNP, but I've already found answers confirming that won't work) on Cisco IOS? I'm practicing at home and I've got a 7206 VXR sitting on the edge of my home network. Obviously, not many production environments, if any, would have reason to enable either so I'd be surprised if there is a way.
That being said, does anyone know if any workarounds? For example, random application X is expecting inbound traffic on port 28321; is it possible to have the router dynamically forward the port?
