While I understand that the BitVisor (v1.1) documentation manual (v1.0) is very dated given all of the new features and changes that are out in the BitVisor v2.0 (mercurial) release, I would like to ask for a bit of clarification on how bitvisor functions relative to the "vpn.mode" setting: Page 20 of the manual says: " The possible values of L2Trans and L3Trans correspond to transparent layer 2 and layer 3 modes, used for testing. In the L3IPsec mode, BitVisor will create the IPSec connection for data transmission. " Thus vpn.mode can be set to (L2Trans | L3Trans | L3IPsec) options. What I read out of this is: <ul> <li>L2Trans --- This mode is a virtual switch which uses the MAC address for addressing</li> <li>L3Trans --- This mode is a virtual router which uses the IP (IPv4 or IPv6) or other protocol for addressing and routing</li> <li>L3IPsec --- This mods make bitvisor act as an IPsec "client" to connect to an external SWAN IPsec capable server like you might have by using a SoftEther VPN Server (<a class="moz-txt-link-freetext" href="https://www.softether.org">https://www.softether.org</a>) which supports IPsec clients and connecting to it via bitvisor. </li> </ul> My questions here are how the L2Trans and L3Trans function. <ol> <li>Is it such that they act as virtual switch/router "server" so that others can connect to them which you might see in a private LAN configuration with multiple non-bitvisor clients connecting to a bitvisor node that is running a switch/router? </li> <li>Can other bitvisor instances connect to each other in these modes such that routers/switches can form a mesh network?</li> <li>Or, depending upon the above then does this allow for switch/router bridging?</li> </ol> For the L2/L3 switch/router questions, I would also be interested in how these modes are configured to make them functional as the manual does not really go into it much, and presumably without encryption I would guess if they act as normal virtual devices while encryption in the modes can be discussed much later, perhaps. Thanks again and have a great evening, Lonnie </body> </html>
