viewtopic.php?f=4&t=34068&p=106063#p106065


Hello,

after more than 20 hours spent on this problem, i don't find any solution...

im trying to install an open vpn server on my windows server 2016

no error during install
i have 3 "TAP" cards
i have tried to disable / enable cards, reboot server, router, services, etc...

my config file (very basic) :

port 33126
proto udp4
dev tun
ca ca.crt
cert server.crt
key server.key
dh dh.pem
server 10.6.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt
keepalive 10 120
persist-key
persist-tun
status openvpn-status.log
verb 4

and my log :

2022-04-10 15:16:41 us=46000 WARNING: --topology net30 support for server configs with IPv4 pools will be removed in a future release. Please migrate to --topology subnet as soon as possible.

Most likely, you already have your server running on that port.

yes you re right my server was already listening on port 33126...

but now i ve got a routing problem, i can connect to my vpn, i gett an ip : 10.6.0.6 but i don't see anything on my LAN...

im surprised not seeing the ip used by my client 10.6.0.6 ?
ip used by VPN is 10.6.0.0 on server config
ip used by my gateway is 192.168.1.1

and i ve this information on log :

You can safely ignore this.

You only can ping 10.6.0.1 as your openvpn server . At the moment you didnot NAT at windows at all. . You need install routing and remote access with custom option then open routingandremote access . under the ip4 tree open NAT network after that on right windown click new then add new inteface . Just chose real internet card and choose option this is public interface then ok. click new interface again then add new interface then ok just leave as it .

This is how NAT in windows work if you can do that you will have internet on openvpn client.

i ve just tried your method but my TAP adapter is not visible in routing and remote access function !

ok i ve succeded in adding my card connected to internet into NAT section and i checked "public connection" and "enable NA on this..."
it seems to be working on output packets (i see them into mapping table) but i got zero "inpu" packet from internet. i ve tried to disable firewall on w 2k16 and on my physical router but itt has changed nothing, i do not receive any packet from the outside

You need add openvpn tab interface too and leave all that default .it should work .
