Re: [Openvpn-users] arp over routed VPN

I should have elaborated a bit more. There are usually properly routed solutions for anything you need to do. There are exceptions, like some old networked video games. Network file shares and such have options like WINS and DNS for service discovery. Eric Crist > On Nov 9, 2017, at 7:22

If you want bridging, you probably don’t know what you’re doing. Eric Crist > On Nov 9, 2017, at 12:23 PM, Rajyaguru, Chirag (GE Digital) > wrote: > > Hi Daniel, > > I think you are looking for Bridging not routing and thus use >

Hi Daniel, I think you are looking for Bridging not routing and thus use https://community.openvpn.net/openvpn/wiki/OpenVPNBridging Thanks, Chirag On 11/9/17, 10:20 AM, "Daniel Miller via Openvpn-users" wrote: I'm probably misunderstanding the

[Openvpn-users] arp over routed VPN

I'm probably misunderstanding the purposes of things, but... I have a Linux VPN server and a Windows client.  I want the client to be able to see at an "arp" level all the server-side LAN devices.  At the moment, I'm using a routed (tun) connection.  The server LAN and the client LAN are
