Is it possible to use NSA325v2 as VPN server?

SoftEther should be OpenVPN compatible: https://www.softether.org/1-features/1._Ultimate_Powerful_VPN_Connectivity#Support_OpenVPN_Protocol

double psot

In theory it should work. In reality it does not. At least not for me. Do not know why yet. The Windows SoftEther client works immediately. Android won't work no matter what I try.

It may also be a problem because cable ISPs don't give real IPs.They use Dual Stack / DS Lite. So maybe OpenVPN is unable to connect due to that?
But Windows works with the SoftEther client, so it should be possible witht tthe right client/protocol

For the client it doesn't matter. But the server (any server) needs an open port on the internet. In case of DS Lite you have no public IPv4 address, so you can't forward on IPv4. But on IPv6 it should be possible to unblock a port (on IPv6 you don't need to forward, as all devices in your network should have a public IPv6 address). So the connection should work over IPv6, when you have configured your router to forward the packages. Provided the clients have an IPv6 address.

I gave my router an IPv6 address and managed to connect to it now using this address directly.

I will check if I can make the DNS service of SoftEther connect to this instead of to the IPv6 of the WAN.

So, if anyone ever finds this thread and needs help:
add "v6" before the ddns address to force IPv6.

Or contact me ;-)

Oh man, now I messed it up again and can't remember how I got it to work. Seems like the GCONV_PATH was missing again and now I do not remember how I properly added it

root@vpnserver# printenv
SHELL=/ffp/bin/sh
TERM=vt102
OLDPWD=/e-data/e9902f35-4024-4b41-9626-08c2131c7087

PS2=>

The GCONV_PATH should be correct but I am getting a segmentation fault.

What did you do to mess it up?

Your logfile is the log of a script. I can't imagine a script to segfault. So can you provide the log of the crashing binary?

What's in the script?

I have absolutely no idea :-D

I can only imagine that while trying to get ffmpeg to work I somehow inadvertently messed up some environmental variables or uninstalled/updated some package that is now causing this issue.

The script simply contains an export of the GCONV_PATH plus ./vpnserver start.

But I will run the log for the binary as soon as I get home and post that as well.

Never mess with a running system. Especially not a fragile one like our NAS :-D

OK, here we go
