Please note that \fB-x1\fR is kind of a workaround option. While it may help under some circumstances, it is better to solve the problem at its origin, e.g. properly implementing dependencies in your startup script to ensure all network interfaces and the VPN adapter you will use are completely setup before you start vlmcsd.
.IP"\fB-F0\fR and \fB-F1\fR"
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.
@ -79,6 +79,28 @@ It is advised not to manually configure your OpenVPN TAP or TeamViewer VPN adapt
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 \fBVPN=vlmcsd\fR to use it.
