ASUS firmware updated, VPN no longer connects

jcarerra · Post by **jcarerra** » Sat Jul 25, 2015 4:27 pm

I updated the firmware in ASUS RT-AC66R to a several-versions-newer Merlin ASUS-wrt (378.55), which apparently has put in a new and different OpenVPN server. I say that because it is exporting an ovpn file for the clients with several lines that are different from before.

Using OpenVPn Connect. I now cannot get a connection to establish using either the old ovpn or the new one.

To say I am disappointed would be a monstrous understatement. It took me weeks of reading, studying, posting, and trial and error (mostly error) before getting it to work the first time. I am an old techie, but completely ignorant in vpn's. I've looked at everything I can. Same as before--but doesn't work, with either client ovpn config. Arghh.

Anybody willing to help me resurrect this?
What do you want to see?

Ina different thread, which I have closed, was this:

Set --verb 4 in your configs for your --log and try again.

Is your key created with a password by ASUS-wrt

please post details of your config

Key? Password?
Only password is the one associated with each authorized client user--entered in the server as authorized users, and entered in the client when connection startup is commanded.
Server is set with option for "Auth mode = static key" and "Username / Password Auth. Only=NO."

As I recall (90%?) ca was created by the OpenVPN+[whatever the firmware contributes] in the original setup and copied to client config. The other certs, keys, dh parameters, were created using easy-rsa tools, and copied into the fields to place them in the server config GUI and into the client ovpn. In server, they are called

Certificate authority
Server certificate
Server key
Static key
Diffie Hellman parameters

In the client config (added by me), they are
<ca>
-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----
</ca>
<cert>
-----BEGIN CERTIFICATE-----
-----END CERTIFICATE-----
</cert>
<key>
-----BEGIN PRIVATE KEY-----
-----END PRIVATE KEY-----
</key>
<tls-auth> NOTE: the newly exported client config file uses <secret></secret> for this section, though I have tried the config with it named both ways.
-----BEGIN OpenVPN Static key V1-----
-----END OpenVPN Static key V1-----
</tls-auth>

Here is the client ovpn...certs removed of course
how would I add the verb 4? this client does not use dashed so just
verb 4 ?
=========
client
mode p2p
dev tun
ifconfig 10.8.0.2 10.8.0.1
proto udp
remote 50.88.131.153 1194
float
cipher AES-256-CBC
comp-lzo adaptive

<ca>
</ca>
<cert>
</cert>
<key>
</key>
<tls-auth>

Ref: topic19316.html

According to that thread this is a server error .. So we would need your server config and log file please.

If there is no specific option in your setup screen try using verb 4 in the custom options field (if there is one).

Have you tried the Asus Forum:

I have made some changes since that log from before.
Here is the latest sequence from log.
Verb 4 is not active yet.
And when I make a change, it can be a while before I can get results as I have to drive from the house to connect to a wifi not going through my own router, which is also the vpn server--it never worked trying to tunnel into my own device with client connected to my own device)

One thisg I just noticed is that the server is just constantly looping through attempts to 'get up' as shown here...

Server config--
oops, can't upload pics. I will find a place to put them and then IMG them in another post.

Server config

If you click on "Content modification...keys..." you get a screen with fields to paste in the static key, ca, serv cert, serv key, dh.

I added "verb 4" (no quotes) to the Custom Config area below the dns push line,
turned server off and back on.
Here is log result:

that client config wont work if you are using "Authorization Mode: Static Key"
you are missing the option

Code: Select all

secret static.key

it looks like it's a drop down menu , so if you want to use ssl/tls ( with client/server certs) there should be an option for that in the drop down menu on your router.
i think the certificates are useless with "Authorization Mode: Static Key"

I do not have access to Asus-Merlin so the following comments are only (*1) hunches:

If you are using static.key mode then Titex comments sound accurate .. Your client config is missing the static.key .. Take a look at the HOWTO for general setup help:
static-key-mini-howto

Some other things which look badly wrong:

I don't know where you specify your network mask but it looks like you have a mask of 240.0.0.0 (*1)

This must be a Asus-Merlin thing (*1) because it is wrong #1) --ifconfig should not be an parmeter here #2)--ifconfig parameters are bogus ...

Have you tried Asus:

My 99% lack of knowledge of vpn's comes into play here!
OK, one at a time..

a. Before the firmware upgrade, the config did work without secret static.key, but I will add it..ah, where?
I assume you mean the client needs it, but not sure. The server IS told there is a static key by the item "Authorization Mode: Static Key"--and there is a static key put in on the page (not shown) that is opened by clicking the yellow "Content modification of keys..."
But to the guts...I thought that "Authorization Mode: Static Key" added a key verification (in addition to uesr/password to AUTHORIZATION only (login)--not doing anything to the tunnel encryption, which was handled by the cert/keys on each end. Is that wrong?

So when it was working before, are you saying it was using entered static key for encrypting the tunnel and ignoring the keys entered for <cert></cert><key></key>...or what?

b. "there should be an option for that {ssl/tls ( with client/server certs) [but it would be 'keys' would it not?]} in the drop down menu on your router."
Very confused. Is that not the "Authorization Mode: Static Key" item which turns that on?

Wow, This is going off the rails fast.

What is blowing my mind is that the config I am using now on the server end is EXACTLY what I was using before the FW update (unless I have screwed up copying the settings back in)--and it worked then.

SO much to address!

One at a time

Code: Select all

I don't know where you specify your network mask but it looks like you have a mask of 240.0.0.0 (*1)

Everything I specify is posted in the images and the posted client ovpn, so I have no idea where that comes from.
