Pradeep, I reproduce it now, thank you very much for your detailed configuration and procedure. I have no idea why it doesn't work reliably with this test while it does work with a regular IP address, it could be an on-wire protocol issue, I'll wait for Emeric tomorrow in the morning and we'll check this together.
All I can say for now is that it *seems* that the first update is always OK in both directions and that after this one only connections sent to the first one who sent the first update continue to work. Maybe there's a state machine bug somewhere, maybe even related to the length of the key or whatever. We'll keep you informed! Thanks! Willy
