Hello, VTUN developers, Does VTUN have the plan to support IPv6?
In environment of only IPv6, IPSec seems to become a
standard VPN technology. However, VTUN is very
convenient in the dual stack environment of IPv6 and
IPv4, if VTUN supports both.
I implemented my poor patches, though development for
IPv6 of VTUN may be started already.
1. vtun-3.0.1-ipv6bone.patch
This patch enables that VPN connection via IPv6
bone.
2. vtun-3.0.1-ipv6linuxtun.patch
This patch enables that the IPv6 packet can be
passed in VPN tunnel of Linux TUN (not TAP)
device. I referred OpenVPN code.
But there are the following problems still in my poor
patches...
- Only "getaddrinfo()" (POSIX.1-2001) is used for
name resolution. Therefore OS which doesn't support
IPv6 can't compile and use VTUN.
It's better to support both of old gethostbyname()
and new getaddrinfo() by using GNU autoconf.
- In IPv6, the option "bindaddr{ iface ... }" doesn't
work well. Because one network device has two or
more IPv6 addresses.
- The function to pass IPv6 via TUN is implemented for
only Linux because of the limitation of my test
environment.
Please refer the attacted patch file. If this patch can
be useful even a little for official IPv6 development,
I'm very glad.
Thanks,
