Nighthawk r7500 vpn setup
I'm new to VPN but learn quickly. I'm trying to setup VPN on my router for a layer of security for my home. I am getting error messeges with openVPN. Following the instructions on the router, many for...
After reading a LOT of information I decided to sell my R7500 and buy a R7000P I flashed it with DD-WRT and was done in about an hour... Super easy. I'm not sure why Netgear does not have more functionality built in the standard interface. Thank you all for the replies.
I just bought a Netgear R7000P (Firmware Version V1.2.0.22_1.0.78) to replace an Asus RTN56U.
That router never had good wifi range, and after two years, the 5GHz connection would just die, and I needed to reboot regularly.
But, the VPN seemed better to me than the OpenVPN on the R7000.
On the R7000, it seems that port 80 is open to the world as soon as you enable VPN. I don't like that.
On the R7000, there is only one login, admin? Is that correct?
On my Asus, I had separate long user names and passwords for each VPN user.
I don't understand having every user log in as admin, and therefore allowing every VPN user full admin access.
Can I control what IP addresses or subnets can access port 80?
If I deliver the "smartphone.zip" file via some method, does port 80 have to be used at all?
If I deliver the zip file, do they ever need the admin login?
I think I only need TUN, but I see no way to disable TAP.
I will be using primarily an iPad into my VPN, often an Android phone, occasionally Windows and Mac.
I'm not sure what you mean by port 80 being open to the world when you enabled the VPN server. When it's enabled, it'll listen on port 12974--if memory serves--for incoming VPN client connections. I also am not quite sure what you mean by one admin login for the VPN. Your old Asus router likely used an older PPTP VPN server with simplistic un/pw combos as the only method for logging in. The OpenVPN server on the Netgear routers uses client certificate chains (i.e. the .ovpn file you download from the GUI after turning it on). Yes, the Netgear implementation only lets you create a single .ovpn file, and thus, only a single discrete client, but you can connect I think up to two or four VPN clients with that cert on the R7000 (I think the R7500 supports four or eight??). Again, I'm not sure what you mean by VPN user having full admin access--the point of the VPN is to get a remote client onto your LAN, nothing to do with admin permissions. I think most mobile clients use TUN and desktop OS clients like Windows use TAP.

I was conflating OpenVPN with the Netgear implementation.
I have a Linux OpenVPN server, and connecting to it on with a standard browser on port 943 (not 80) provides a way for a new client to download config files and continue with their OpenVPN. This is protected by a simple user/password login, but multiple possiblities.
I had confused that with the Netgear, where port 80 is only open on the LAN, not the WAN, but provides a path to the config downloads. The login here is a password, and user admin.
(nmap from the LAN to the public IP address showed the same results as a scan to the internal Private IP, which is misleading, but I see that is not uncommon amongst routers. I don't think that happened on the Asus, but I could be mistaken.)So, Public ports are not the problem that I thought they were. I need to supply my users with the .ovpn and associated files, because one needs to log in on the local LAN as admin in order to fetch them.
I have been able to connect Android OpenVPN client to both my OpenVPN server and to the R7000P.I can connect Windows 10 to the OpenVPN server, but I cannot connect to the R7000P.
It fails with errors that the #mitm suggests are server side problems, but my Android connects okay.

The certificate verification WARNING appears repeatedly in the log, but seems to have no effect. The ROUTE message, no effect.
The instructions say: "Step 5: For a client device with Windows, you need to modify the VPN interface name to "NETGEAR-VPN". The VPN interface usually has a Device Name as "TAP-Windows Adapter"."
I had one named "Ethernet #2", but i noticed in small print that it said "TAP-Windows Adapter V9"I couldn't change the bottom line of that description, but I could change the name, to "NETGEAR-VPN".
Now Windows VPN connection to the R7000P works.
see the attached screenshot of what my Network Connections panel looks like (VPN not connected right now.)
