Yes, we got that. You've said that before. You should talk about the
PROBLEM, not the IMPLEMENTATION you've created.
Your solution may very well be wrong.

Yes, they each connect to their own UDP port. Why? You don't seem to
be clear on that.

Did you read my previous message? You can create unique virtual
servers per client.

Customer? Tenant? You're using vague terminology. Be specific. Who
is doing what and why?

You're describing your implementation. NOT the problem.

Could you explain why you need to say 5-6 tunes "EACH CUSTOMER GETS
THEIR OWN UDP PORT"?
It's unnecessary and annoying. It means you either think we're idiots
and don't understand it, OR you're stuck on your implementation, and
REALLY WANT TO TALK ABOUT IT.

No. I've explained that you DO NOT need to use separate ports.
Instead of listening and trying to understand, you've asked again how to
use multiple ports.

Except that you've got to modify the server source because your design
i.e. your design is crap. It's overly complicated, and unnecessary.
Can you answer this one simple question:
- do multiple customers use the same the RADIUS client IP?
Which is it?
My guess is NO. In which case your design is massively
over-complicated and unnecessary.
Are you prepared to think about it? i.e. pay attention, and have a
response which *doesn't* say 6 times "I HAVE MULTIPLE UDP PORTS" ?
It's annoying. You're asking for help and then ignoring the answers.
Read and learn, or stop asking questions.
