jimwillsher Background: I'm new to OpenVPN, but yesterday I installed six separate OpenVPN servers. These are all entirely isolated, one at each of my customers. I've used the Community x64 download, installed onto Server 2012R2. I want to be able to connect to the customers and use other apps on my iPhone/laptop to reset AD passwords etc. when I am not at their sites. On five installs, everything works great. I can connect from my IOS devices and access resources on the remote LAN. On one install, I cannot get it to work for love nor money! The VPN client connects successfully, and I can ping the remote VPN server (10.8.0.1) but I cannot ping any devices on the remote LAN. The one difference I can see between the two setups is that the TAP adapter on the OpenVPN servers which work is showing in "Network and Sharing Centre" as a Domain network. But on the system where it doesn't work, it shows as Unidentified (and therefore Public). I don't believe it's a firewall issue though, as I have completely disabled the Windows firewalls for testing. I am using entirely default values for everything (abpart from I have "topology subnet" enabled in the server config files on all servers). However on the network where it doesn't work, the main network itself is 10.10.10.x (255.255.255.0); the VPN network is still the default (10.8.0.x). Can anyone suggest a way forward? I've googled to death, adding default gateways, changing the adapter NDIS type, everything. I've uninsatlled, reinstalled, rebooted, all the normal tricks. Many thanks :-) Jim
TinCanTech jimwillsher wrotethe VPN network is still the default (10.8.0.x)If all the servers are 10.8.0.0/24 then you can only connect to one at a time from a single device ..
jimwillsher Sorry, let me clarify. One remote server subnet is 192.168.7.x/24 One remote server subnet is 192.168.2.x/24 One remote server subnet is 192.168.5.x/24 One remote server subnet is 192.168.9.x/24 One remote server subnet is 192.168.3.x/24 One remote server subnet is 10.10.10.x/24 I can connect to them all, individually, one at a time. On all the first five, I can ping devices on the LAN (e.g. on the first, I can ping 10.8.0.1 and also 192.168.7.11) On the last one I can ping 10.8.0.1 but nothing on 10.10.10.x. Jim
TinCanTech You have undoubtedly proven that openvpn works .. now you just have to figure out which other step your forgot on your failing network .. perhaps a route on the default gateway ?
jimwillsher Hmmm.....having been through a comparison list several times, I'm pretty sure it's not that. BUT......I think I now have it working. I have the VPN server installed on a Hyper-V VM - the same as I have at all the sites. So just for kicks I have deleted the Hyper-V virtual network switch and recreated it.....and it seems to be working. Microsoft......
jimwillsher And to round this off, the TAP adaptor in my VM (e.g. on the server side) is now correctly in the Domain profile. All good :-)
