VPN connection

7.1 Explanation of VPN connections
The IPsec protocol suite
The SINAUT MD741-1 uses the IPsec method in the tunnel mode for the VPN
tunnel. Here, the frames to be transferred are completely encrypted and provided
with a new header before they are sent to the VPN gateway of the partner. The
frames received by the partner are decrypted and forwarded to the recipient.
Roadwarrior mode and standard mode
There are two modes for VPN connections:
Roadwarrior mode
●
In the Roadwarrior mode, the SINAUT MD741-1 can accept up to 10 VPN
connections from partners with an unknown address. These partners can, for
example, be mobile partners that obtain their IP address dynamically. In
addition to this, VPN connections can also be operated in standard mode.
The VPN connection must be established by the partner. In Roadwarrior mode,
the SINAUT MD741-1 can only accept VPN connections but cannot establish
them actively.
Standard mode
●
In standard mode, the address of the VPN gateway of the partner must be
known so that the VPN connection can be established. The VPN connection
can either be established by the SINAUT MD741-1 or by the VPN gateway of
the remote station.
