--block-outside-dns
Block DNS servers on other network adapters to prevent DNS leaks.
This option prevents any application from accessing TCP or UDP port 53 except one inside the tunnel.
It uses Windows Filtering Platform (WFP) and works on Windows Vista or later.
This option is considered unknown on non-Windows platforms and unsupported on Windows XP, resulting in fatal error.
You may want to use --setenv opt or --ignore-unknown-option (not suitable for Windows XP) to ignore said error.
Note that pushing unknown options from server does not trigger fatal errors.
On uClibc, the ifaddrs.h support is optional. While the default
Buildroot uClibc configuration has it enabled, some external
toolchains may not. Therefore this patch detects that and adjusts
softether usage of ifaddrs accordingly.
Based on an initial patch from Bernd Kuhls.

Formerly, SKIP_CPU_FEATURES is automatically detected by system
processor. However, "^(armv7l|aarch64|s390x)$" does not cover all
processors that cpu_features should be skipped.
"armv6", "armv7", "mips", "mips64" on FreeBSD are examples [1]
that cpu_features is not correctly skipped.
This change intends to build SoftEther without any modifications on
CMakeLists.txt on such processors.
cmake . -DSKIP_CPU_FEATURES=1

DbDir : directory to store files such as vpn_server.config and backups etc
LogDir : directory to write logs (sub directories is created in this dir)
PidDir : directory to put PID files such as .ctl-* .pid-* .VPN-*
Currently the systemd service unit files are installed
into /lib/systemd/system if that directory exists. This
might not be optimal for every user, e.g. when the build
system is not the target system or when building as an
unprivileged user using CMAKE_INSTALL_PREFIX.
Make this configurable by adding a cached cmake variable
CMAKE_INSTALL_SYSTEMD_UNITDIR. Usage:
- install unit files into /lib/systemd/system if it exists (old
behavior)
cmake
- don't install unit files
cmake -D CMAKE_INSTALL_SYSTEMD_UNITDIR=
- install into absolute path
cmake -D CMAKE_INSTALL_SYSTEMD_UNITDIR=/path
- install into path relative to ${CMAKE_INSTALL_PREFIX}
cmake -D CMAKE_INSTALL_SYSTEMD_UNITDIR=path
The function has been greatly improved, here are some of the changes:
- The required SESSION (c->Session) parameter is checked correctly: the function returns immediately in case it's NULL. Previously, the function didn't return in case the parameter was NULL; multiple checks were in place, but not in all instances where the parameter was dereferenced.
- The resolved IP address is cached with all proxy types.
- The "RestoreServerNameAndPort" variable is documented.
- The Debug() messages have been improved.
