Enables a compatible VPN adapter to create additional local IPv4 addresses (like 127.0.0.1) that appear as remote IPv4 addresses to the system. This allows product activation using a local instance of vlmcsd. This feature is only available in Windows and Cygwin builds of vlmcsd since it is not of any use on other operating systems. Compatible VPN adapters are Tap-windows version 8.2 or higher (from OpenVPN) and the TeamViewer VPN adapter. There are two special \fIvpn-adapter-name\fRs.

The \fIvpn-adapter-name\fR is \fBnot\fR case-sensitive. If the \fIvpn-adapter-name\fR contains spaces (e.g. Ethernet 3), you must enclose it in quotes.
The default \fIipv4-address\fR is 10.10.10.9 and the default \fIcidr-mask\fR is 30. If you are using the default values, your VPN adapter uses an IPv4 address of 10.10.10.9 and you can set your activation client to use the easy to remember address 10.10.10.10 (e.g. slmgr /skms 10.10.10.10 or cscript ospp.vbs /sethst:10.10.10.10).

It is advised not to manually configure your OpenVPN TAP or TeamViewer VPN adapter in "Network Connections". If you set the IPv4 configuration manually anyway, the IPv4 address and the subnet mask must match the \fB-O\fR parameter. It is safe leave the IPv4 configuration to automatic (DHCP). vlmcsd will wait up to four seconds for the DHCP configuration to complete before binding to and listenin on any interfaces.
You should be aware that only one program can use a VPN adapter at a time. If you use the TeamViewer VPN adapter for example, you will not be able to use the VPN feature of TeamViewer as long as vlmcsd is running. The same applies to OpenVPN TAP adapters that are in use by other programs (for example OpenVPN, QEMU, Ratiborus VM, aiccu, etc.). The best way to avoid conflicts is to install Tap-Windows from OpenVPN, cd to C:\\Program Files\\TAP-Windows\\bin and run addtap.bat to install an additional TAP adapter. Go to "Network Connections" and rename the new adapter to "vlmcsd" and specify \fB-O vlmcsd\fR to use it.

Allow (\fB-F1\fR) or disallow (\fB-F0\fR) binding to IP addresses that are currently not configured on your system. The default is \fB-F0\fR. \fB-F1\fR allows you to bind to an IP address that may be configured after you started \fBvlmcsd\fR. \fBvlmcsd\fR will listen on that address as soon as it becomes available. This feature is only available under Linux (IPv4 and IPv6) and FreeBSD (IPv4 only). FreeBSD allows this feature only for the root user (more correctly: processes that have the PRIV_NETINET_BINDANY privilege). Linux does not require a capability for this.

Enables a compatible VPN adapter to create additional local IPv4

to the system. This allows product activation using a local
instance of vlmcsd. This feature is only available in Windows
and Cygwin builds of vlmcsd since it is not of any use on other

sion 8.2 or higher (from OpenVPN) and the TeamViewer VPN

ble VPN adapter. A single dash (-) disables the use of a VPN
adapter if one has been configured in vlmcsd.ini(5). The vpn-
adapter-name is not case-sensitive. If the vpn-adapter-name con‐
tains spaces (e.g. Ethernet 3), you must enclose it in quotes.
The default ipv4-address is 10.10.10.9 and the default cidr-mask
is 30. If you are using the default values, your VPN adapter
uses an IPv4 address of 10.10.10.9 and you can set your activa‐
tion client to use the easy to remember address 10.10.10.10
(e.g. slmgr /skms 10.10.10.10 or cscript ospp.vbs
/sethst:10.10.10.10).
The dhcp-lease-duration is a number optionally followed by s, m,
h, d or w to indicate seconds, minutes, hours, days or weeks.
The default dhcp-lease-duration is 1d (one day). It is normally
not required to change this value.
It is advised not to manually configure your OpenVPN TAP or
TeamViewer VPN adapter in "Network Connections". If you set the
IPv4 configuration manually anyway, the IPv4 address and the
subnet mask must match the -O parameter. It is safe leave the

The default ipv4-address is 10.10.10.9 and the default cidr-mask
is 30. If you are using the default values, your VPN adapter
uses an IPv4 address of 10.10.10.9 and you can set your activa‐
tion client to use the easy to remember address 10.10.10.10
(e.g. slmgr /skms 10.10.10.10 or cscript ospp.vbs
/sethst:10.10.10.10).
The dhcp-lease-duration is a number optionally followed by s, m,
h, d or w to indicate seconds, minutes, hours, days or weeks.
The default dhcp-lease-duration is 1d (one day). It is normally
not required to change this value.
It is advised not to manually configure your OpenVPN TAP or
TeamViewer VPN adapter in "Network Connections". If you set the
IPv4 configuration manually anyway, the IPv4 address and the
subnet mask must match the VPN= directive. It is safe leave the
IPv4 configuration to automatic (DHCP). vlmcsd will wait up to
four seconds for the DHCP configuration to complete before bind‐
ing to and listenin on any interfaces.
You should be aware that only one program can use a VPN adapter
at a time. If you use the TeamViewer VPN adapter for example,
you will not be able to use the VPN feature of TeamViewer as
long as vlmcsd is running. The same applies to OpenVPN TAP
adapters that are in use by other programs (for example OpenVPN,
QEMU, Ratiborus VM, aiccu, etc.). The best way to avoid con‐
flicts is to install Tap-Windows from OpenVPN, cd to C:\Program
Files\TAP-Windows\bin and run addtap.bat to install an addi‐
tional TAP adapter. Go to "Network Connections" and rename the
new adapter to "vlmcsd" and specify VPN=vlmcsd to use it.
