AW JEEZE! It WAS the date/time! I assumed the date was correct because I was using an NTP server (nist1-lv.ustiming.org) but I guess it was giving me the wrong info for some reason? I switched to 0.pool.ntp.org and now the time is corrected. I looked back at your guide and found the part about the time being correct, and I remember checking the time up at the top of my router homepage and assumed it was off a few hours due to time zones or something. But it doesn't show the date and I didn't know the date was that far off until I started logging and saw December in there! Dangit! I knew it was something stupid. I even started from scratch twice to make sure that I didn't just miss a step.

Well, at least it now sort of connects, but now I just get warnings that I need to work through:
Fri Sep 27 15:54:05 2019 WARNING: 'link-mtu' is used inconsistently, local='link-mtu 1549', remote='link-mtu 1570'
Fri Sep 27 15:54:05 2019 WARNING: 'cipher' is used inconsistently, local='cipher AES-128-GCM', remote='cipher AES-128-CBC'
Fri Sep 27 15:54:05 2019 WARNING: 'auth' is used inconsistently, local='auth [null-digest]', remote='auth SHA256'
Fri Sep 27 15:54:05 2019 WARNING: 'comp-lzo' is present in remote config but missing in local config, remote='comp-lzo'

then I just get this message repeated a couple of times and then it disconnects.
Fri Sep 27 15:59:28 2019 AEAD Decrypt error: cipher final failed

They're probably all just issues with the settings and I'll try working through each one at a time when I have time. Thanks for your help!

I might have some feedback for your instructions that I'll put together if you're interested in getting some feedback from a complete newbie.

Feedback is always welcome Smile

The time has to be right otherwise ceertificates are not valid like you have found out.

The link MTU warning you can ignore.
The 'auth' is used inconsistently, warning you can ignore

The cipher warning is due to server and client are not using the same cipher, the new cipher is the best to use that is AES-128-GCM, but both client and server have to use that.
The AEAD decrypt error also has to do with that.

Did you place " ncp-disable " in the additional config?

The comp-lzo warning you can also ignore although in both client it should be disabled (if you use a configuration file for a client there should be no "comp-lzo" in the file) and if both have it disabled (or at least use the same settings) the warning should be gone

Hmm, the reason for the cipher error is that on my version of DD-WRT, I only have AES-128 CBC (not GCM, all of my options are CBC instead of GCM). I just updated the client config to use CBC.

I accidentally left LZO Compression enabled on my router config (funny how many times I've gone over the settings, even started from scratch twice, and I still missed something like that).

Yep, I am using ncp-disable in the additional config because the guide mentioned that if I was using "Redirect default gateway" to use it (not sure what that does, but I only enabled it because I saw it in your screenshot).

But now I'm getting no errors and am able to connect! Thank you!

So, onto the feedback. When I created my certificates, it asked me for a "Challenge Password" and an "Optional Company Name". Not sure what these are used for as I was never asked for it again, but you might want to mention this in step 3 and step 4.

Also might want to provide directions on how to verify the date, because maybe the time in the top right might be correct, but it doesn't show the date and I don't know of anywhere else to verify the time AND date besides the logs (where I found out mine was WAY off). Perhaps bold that "Before you start check if the time is right on your router" and add "time AND DATE" to it for idiots like me.

I had other questions that I had written down, but they were answered while reading the guide further (the screenshots were GREAT at verifying I had the right settings).

I think that's it, but thanks again for doing this. This is BY FAR the best guide that I've read for setting up OpenVPN.

Great you got it working and thanks for your feedback, I will look into it.

I had to add one additional step to the guide.

I could connect to OpenVPN server however I could not access the Internet from the client.

In DD-WRT - Administration > Commands , I had to add the following lines, then click Save Firewall.

Where 10.8.0.0 is the OpenVPN subnet.

Code:
WAN_IF="$(route -n | awk '/^0.0.0.0/{wif=$NF} END {print wif}')"

iptables -t nat -I POSTROUTING -s 10.8.0.0/24 -o $WAN_IF -j MASQUERADE



Can you add this to the guide? I don't think it is mentioned?

Thanks for your feedback.

It is in step 8a on page 6.
Let me know if it is not clear or if you have trouble with it.

Yes you are right, I got mixed up between guides. This command you mentioned also now works for me.

iptables -t nat -A POSTROUTING -o $(nvram get wan_ifname) -j MASQUERADE

But glad that it is working

I can get OpenVPN to work in TAP mode, but unfortunately I can't use that with Android which is really where I want to use the VPN.

I've followed this guide to the letter (thanks for posting it), and it seems that I can't get the OpenVPN server to start on the router whenever I select Tun.

I've attached images of what I see in Status -> OpenVPN and the settings under Services -> VPN.

You can see that there's no mention of any server running in the status page, even after a reboot. The client of course fails to connect as a result.

Is this a common issue? Is there something I'm missing?

The router I have is a TP-Link Archer C7 V4 running v3.0-R40559.

It's disappointing considering the original TP-Link firmware had OpenVPN functionality that worked quite well, it just had a nasty bug that it would randomly drop PPPoE connections on the WAN port, hence why I'm here.

If the server does not start it usually indicates a major setup fault.
Often the certificates/keys.
But in this case I suspect the netmask.
Use 255.255.255.0

Zoot7,
I suggest to update the DD-WRT build you are using Rolling Eyes

Okay that was it - the server is now starting. I feel stupid now since I should have spotted that - Thank you! Smile

I can now also connect from outside the home network via the Android client on my phone, the only issue now is that I can't access the internet or my local server when connected to the VPN. I do have the firewall rules enabled in the guide.

New to all of this, I'd appreciate the help.

To be positive since the last poster probably thinks I'm complaining Wink, the nasty bug with WAN connection dropouts is gone since flashing DD-WRT. It boggles the mind that TP-Link couldn't get it right with their own firmware.

When connected can you ping anything on your network?

Can you connect to your routers GUI itself when connected?

Can you show me the output of the following 4 commands (telnet/Putty to yout router):
Code:
nvram get wan_iface
nvram get wan_ifname
get_wanface
echo WAN_IF="$(route -n | awk '/^0.0.0.0/{wif=$NF} END {print wif}')"


Can you post a picture of the Status/OpenVPN page from the router when you are connected (show the whole page)?

I am trying to establish if you can have traffic over the network.

Some pointers:
always test from outside your network so with your phone on cellular.
Check the LZO compression settings on client and router

So... when I connect with my phone from outside the WAN I can't access the internet regularly and I can't access any local IPs including my home server or the router's GUI either.

(The ping attempts time out)

Here are the outputs for the above commands:

Code:
root@DD-WRT:~# nvram get wan_iface
vlan2

root@DD-WRT:~# nvram get wan_ifname
vlan2

root@DD-WRT:~# get_wanface
ppp0

root@DD-WRT:~# echo WAN_IF="$(route -n | awk '/^0.0.0.0/{wif=$NF} END {print wif}')"
WAN_IF=ppp0


Here's the OpenVPN log after connecting.
Code:

I see a Authenticate/Decrypt packet error: packet HMAC authentication failed, assuming this is the issue?

Regarding the LZO compression, is there a reason that you've specified to disable it in the guide? You mention re-enabling it above (I currently have it disabled)

On another note - thanks for all the help. Even getting this far is something with all the official guides being very far out of date. Smile

Here's a corresponding log from the client side after connecting.

The time of the AEAD Decrypt error: cipher final failed messages correspond to the Authenticate/Decrypt packet error: packet HMAC authentication failed on the server side.
