softether and IPv6 routing

[vpn_admin]

I have softether setup and IPv4 traffic is working perfectly. IPv6 traffic is not routing correctly. When my clients connect to softether they are getting a IPv4 and IPv6 address from my local network via DHCP. If I ping -4 server4.test.com I get the correct IPv4 address and the server responds. If I ping -6 server4.test.com, the server resolves to the correct IPv6 address but it tries to go out over the internet instead of down the tunnel. The clients connect to the softether server via a IPv4 address. I worked around the problem by disabling IPv6 on the clients but that is not a long term solution. What am I doing wrong?

Get DE https://github.com/SoftEtherVPN/SoftEth ... le-edition

IPv6 Route Management

[vpn_admin]

Thank you for the link. I am assuming I have to update my server to the DE edition. I have a RedHat 8.8 Enterprise Linux server that I trying to update. I am trying to follow the directions at:
https://github.com/SoftEtherVPN/SoftEth ... LD_UNIX.md

When I run:

Code: Select all

sudo apt -y install cmake gcc g++ make pkgconf libncurses5-dev libssl-dev libsodium-dev libreadline-dev zlib1g-dev

I get an error that says Error: Unable to find a match: libsodium-devel
I removed libsodium-devel from the command line and the rest of the modules installed.

Next I am trying to download the source code using:

Code: Select all

git clone https://github.com/SoftEtherVPN/SoftEtherVPN.git

it prompts for a username and password
so I Ctrl-C out of that and do wget https://github.com/SoftEtherVPN/SoftEth ... master.zip

Code: Select all

unzip master.zip
cd SoftEtherVPN-master

./configure

CMake Error at /usrshare/cmake/Modules/FindPkgConfig.cmake:843 (message):

What am I doing wrong?

Windows DE clients do IPv6 Route Management.

The DE is working. What are the chances of the IPv6 route management being integrated into the next release?
