I understand this, and therefore I ask such a specialist as you. After all, you have created an absolutely ingenious product that can really be compared with the creation of Microsoft "Visual Basic"!
I am sure you can give specific advice, because,
for example well-known programs for Android:
Palapa web server
Kws server
and others, written in Visual Basic, not only easily work in root with port 80, but also offer forwarding of external and local ports, if necessary.
Therefore, your instruction can easily do this.
Please tell me, this is really very necessary.
We want to make our own version of such a server for Android.
Thanks in advance.
With great respect.
Alexander.
