Hello @dhikra-marghli8 

NAT-T for vBond ensures that vBond can operate effectively in network environments with NAT, and server STUN for vBond likely means that vBond can function as a STUN server to assist devices in determining their external addresses when they are behind NAT devices.

we config vedge and we config it vbond 
when the interface of vedge is UP it start send stun packet to vbond 
the vbond is reply 
what vedge know from this process 
the vedge using it private IP and send stun packet to vbond, and vbond reply with vedge public IP 
the vedge use both private and public IP to generate the TLOC and send it to vsmart. 
also in this process the vbond keep info. of Private and public IP of each vedge
