Hi.
I've seen this sometimes and you can cancel to let the wizard finished.
This occurs because "security.cfg" has already been synched from another HUB while prompt ask you to give username/password.
Note.
1. If you want to configure HUB-HUB (in the same segment) talk only stick with over Tunnel, you need to disable broadcast feature in every HUBs in the same segment. Here is key in HUB.cfg
broadcast_on = no
2. We would not see the needs (Tunnel talk within the same segment) so often because tunnel-talk is enabled with the purpose of having the talk in secure, or the talk over network where NAT/DMZ are involved.
3. HUB has built-In broadcast feature to send UDP packet to 255.255.255.255 which enables one HUB to detect the other HUBs automatically in the same segment, and sharing HUB information to each other.
Hope it helps
