I have some custom ports and normal ports being forwarded through a ASG 7.2 via DNAT rules.
My issue is that it seems that the Loopback Interface is only letting the predifined ports like 80,21 out and back in, if tried from inside the network. But doesn't forward the custom ports like 56898 or 8767.
This makes it hard to test port forwarding to my servers, until I'm outside my network. Which has tested the rules as good.
Maybe I've misconfigured it, I don't know.
Any help would be great.
Thanks
