SoftEther VPN User Forum

Hi there,
I would like to estabilish a VPN with my PC at home, when I'm away (holiday, work...) and using another laptop

My provider at home uses NAT and I didn't buy from them a static IP
When I'm away from home I will use my laptop, the line given from my smartphone as hotspot

I've already installed "softether" both on my home PC (server) and laptop (client)

I'm a real beginner and just to verify that my job was formally correct, I tried to raise the VPN from inside my home LAN (both PC and laptop then into the same LAN), and it worked!

then, if I move the laptop behind the smartphone hotspot (simulating the normal use), it does not work anymore...

May someone help me?
thanks!

It can not work without public ip

Alternative, slow one, is to use azure provided by softether

do you mean a "static" public IP?

for me no problem if slow, may you please tell me how to go through azure?
Indeed in my installation and configuration I see azure url...

thanks

static is not neccessary, ISP can change after every router reboot your IP, but it must be unique - must be public
SE has got inside the code already procedure to update IP after change (DDNS)

you just write ...........azure.......... instead of ............softether...........

ok, excuse me sky59 for the stupid questions
I'm a real beginner fo this stuff...

I read the softether manual about vpnazure and I still have some issues

I tried to connect from softether VPN client (port 443 is right?) or simply when I try to connect creating a new network connection from windows but I'm not able yet

from VPN client: it connects (validates username and requests IP to dhcp server) but when I check if it is really connected I see "disconnected" and no packets received (see the picture 1)

instead, when I try to connect after having created a new network connection from windows it gets me error "PPP protocol error" (see the picture 2)

argh!

I just tried completely reinstalling VPN server and client with the same unsuccessful results

I strictly and severely followed this procedure:

http://vpnazure.net/en/

but my result is the same: the VPN Client conection become "connected" (only if I choose the port 443, no way for the others...) but if I check if it is really on, I see that it isn't really

for example, iduring connection it ask and receive the IP from DHCP server in the VPN, but the IP assigned is not on the private network of the VPN Server...

summarizing:
my "VPN server" is at home behind my ISP
my VPN client is behind my smartphone as hotspot

please help me to solve this issue
thanks

You are connected, i have no idea what problem you have there..

Do you have local bridge established on server?!

thank you sky59 for your suggestion

I exactly followed that procedure and I think a bridge was installed

see the picture

PS: the port 443 is ok?

Is Realtec controller connected to the network you want to access?

ops... really sorry for this mistake

it works!

I don't understand why it doesn't work unless with azure

Try bandwidthplace.com what is the speed

well...not properly fast...

Download: 1.12Mbps
Upload: 1.24Mbps
Ping: 646ms

anyway you are my god, mate! THANKS!

do you think there is some possibility to let it work without azure?

Yes, to use your own public ip address

yes, I suppose this is the only way

I have to ask my ISP how much it costs a static public ip...

thanks for your excellent support, really /appreciate

Happy to help

Does not need to be static

If you have DSL or ADSL just log into the router and have a look what is the ip, it is likely already public

Then you only need port forward 443

ah ok, thanks for clarifying

I already have a dynamic public IP, but my ISP days it is not reachable from external
I verified that unfortunately it is, I already tried to reach my LAN with port forwarding (as well as I do in office) but I have no chance

indeed they confirmed me that the only way is to buy a static IP

I tried before with openVPN and now with softether

via azure is the first time I'm able to come in!

Softether server can work behind NAT, it is not mandatory for you to get Public IP as long as you use Softether VPN Client software to setup the VPN connection.
In case you dont use Softether VPN Client, IP Public is mandatory for your server side but you dont need Static IP since Softether have it's own dynamic DNS feature (you can use xxxx.softether.net domain instead of your public IP address). Or you can enable vpnazure and connect with SSTP instead of L2TP/IPsec protocol, dont forget that the domain of your server should be xxxx.vpnazure.net not xxxx.softether.net

NO


Another option is to use azure server at university - it has got public ip

If you are not using the Softether VPN client, your IP public is mandatory on your server side, but you do not need a static IP because Softether has its own dynamic DNS function (you can use the domain xxxx.softether.net instead of your domain use public IP address). Or you can activate vpnazure and connect to SSTP instead of L2TP / IPsec

e??
