Hello To Whom May be Listening,

New to the Forum and require advice for setting up Merlin on my brand new ASUS CM-32_AC2600 Router that I have using Comcast as my internet service...

...I currently have Private Internet Access VPN that isn't working without Merlin on my new router.

Thanks in advance for any and all help :]
 
Return and get the standard AC3200 and use the Comcast modem in bridge mode, connected to WAN on the 3200.

We had habitual connectivity issues with our old bridgemode setup connected to a Linksys FlashRouter. Hence the attempt to try our VPN on a single router connected to a comcast dedicated Asus router... appreciate the advice, I may go back to the old setup (slow speed / vpn / connectivity blackouts) or just stay with the current setup (quadruple the speed / no vpn / no blackouts) I'm gonna miss my VPN thou :(

You may find the bridge behaves properly when connected to the Asus. Worth a go!

Go to PIA's web site and search and you will find the settings that you need. PIA works very well with Merlin's firmware on an ASUS router.

Unfortunately a PIA tech support ticket opened and closed with the rep stating that my specific router is unable to run merlin :( thanks for the effort...
 
Try skip certificate dont use that with my open vpn client..
Must define certificate authority: NO
Verify Server Certificate: NO
Worth a try perhaps

Still nothing... even tried it without the certificate

this is what the default portal vpn looks like... I added a description, user name and password along with the uploaded .ovpn file and certificate... for some reason unknown it just wont activate.

Thanks... That would help if I could gain access to the vpn but unfortunately PIA has given me the update that its not possible with my Asus Comcast Specific Router (AC2600) and Merlin doesnt support the router as well as DD-WRT and Tomato... thank you all for the kind efforts and time to reply to my inquiry... Godspeed!

P.S. See below for the fore-mentioned conversation with PIA, maybe this will help someone else who may have a similar issue, good luck!

Hello Francis,

Thank you for the response, attached is the ovpn file that should work however as mentioned default ASUS firmware is not supported as of yet by our services. I would recommend installing Merlin via their site https://asuswrt.lostrealm.ca/download. Flashing Merlin is outside of our scope and we are not liable to any damages if they should occur when flashing the firmware. Just make sure you download the correct one for your device it will be listed via model number.


For your convenience I have included the file that you can try on the default ASUS firmware in plain text as well as attached on to this email:

If you use Merlin you can follow our Merlin guide to use the vpn: which I have included below.


Whilst we cannot officially support Merlin firmware, we've opted to write a setup guide for Merlin as the OpenVPN functionality is based off Tomato firmware. Currently we officially support DD-WRT, Tomato & pFsense.

We will endeavour to ensure that this article is accurate and up to date to the best of our ability.

To Setup Private Internet Access on Merlin firmware.

1. Login to the Asus Router control panel via a web interface.

2. On the left side menu, select the option 'VPN'

3. This will take you to the 'VPN Status' page. Select 'OpenVPN Clients' from the tabs at the top.

4. In this tab, you will be able to configure your OpenVPN clients in order to connect to the internet via your PrivateInternetAccess service.

5. Configure your client as follows:

NGy2E602Yj5rwBxZ_QLdix6ZHIEMwc39WtV-d8EK54nCktW17KWOl6htCEmwDvO-x8e0kWLANnjxslvw5c24IYSvWNvmrtkAcvg-iBq1TFN6yx10Jw30Aqyy8YvZOgkfEIIkTUNpzj9LFB6cFa_wIGY=s0-d-e1-ft



  • Start with WAN: Yes.
    This will start your VPN when you connect to your ISP. If this is set to no, you will need to manually start your VPN service at the router level when your router restarts.

  • Interface Type: TUN

  • Protocol: UDP

  • Firewall: Automatic

  • Authorization Mode: TLS

  • Server Address: Select your address from our server list found here.
    In this example we used 'us-east.privateinternetaccess.com' (New York, USA)

  • Port: 1198

  • Username/Password Authentication: Yes

  • Username: Enter your PIA username (for example P1234567)

  • Password: Enter your PIA password (for example 12345678)

  • Username / Password Auth. Only: No

  • Extra HMAC Authorization: Disabled

  • Auth Digest: Default

  • Create NAT on Tunnel: Yes
6. Click the option next to 'Authorization Mode: TLS' that says 'Content modification of Keys & Certificates.'

7. Download the Certificate Authority from www.privateinternetaccess.com/openvpn/ca.rsa.2048.crt

8. Open the file with a text editor and then copy and paste the contents of ca.rsa.2048.crt into the Certificate Authority.

9. Scroll down to the bottom and click 'Save'

10. Under Advanced Options, configure your client as follow:

TFCAKT9I97CoUdynW4cwd21qd9oRjdYKs_BkoDZoF-DDHxdXuH12PSBwmopA2_441HGRbCdXGK3qTqIuy-bRx_iE_go8VSN8MkbjqQvRk-qLCgc-rPMgu9N4_w9VuQMYNrpRsxTOO6CcwsyCUdOgyICFkZM=s0-d-e1-ft



  • Global Log Verbosity: 1

  • Poll Interval: 0

  • Accept DNS Configuration: Strict

  • Encryption Cipher: AES-128-CBC

  • Compression: Adaptive

  • TLS Renegotiation Time: -1

  • Connection Retry: 30

  • Verify Server Certificate: No

  • Redirect Internet Traffic: No
11. Under Custom Configuration, enter the following:

persist-key
persist-tun

12. Click 'Save'.

13. You will now be able to set the 'Service State: On' (located at the top of the options). Service State on will only stay green and On when your service is correctly configured.

14. To see the status of your VPN service, you may check the 'VPN Status' tab located at the top which will actively poll your connection to give you the latest statistics on your connection.

If the VPN Status page constantly says 'Connecting (server address & port)' it indicates potential issues with the connection settings or Certificate Authority. Please refer to steps 5 and 6 and verify that all settings are correct.
