VPN traffic in UDP packets for passing through a remote device
regardless of whether it supports address translation.

TUNNEL

remote networks. In this mode, the source IP packet is fully
encrypted and added to a new IP packet and data transfer is
based on the header of the new IP packet.
•
TRANSPORT
: As a rule, it is used to encrypt data stream
within one network. In this mode, only the content of the
source IP packet is encrypted, its header remains unchanged
and data transfer is based on the source header.
