pfsense 2.5.2: ExpressVPN connection working by gateway has 100% packet loss

It sounds like you're looking for the Client Specific Overrides

A point for you !

I meant :

All the other menu options are 'server' related.

edit :
I restarted reading you first post (see above).
I decided to enter exactly what you've mentioned.
One exception : I removed my password.

https://www.test-domaine.fr/VPN-Client.png

Compare this huge image with your settings.
Double check for differences.
( edit : I found a difference : my verbosity (log) level is 3 - level 10 is far to detailed, create hundreds of entries a second. Leaving it 10 or 3 has no other side effect )

With these settings :

I monitored 8.8.8.8 to check the VPN-Client connection - RTT is a bit high as I'm based in France, St Jose in the US is not really close.

All I had to to to make the connection works, was switching from :

"automatic mode" to "hybrid mode" and save.
I'm now connected the entire company over Expr*ssVPN ...... I wasn't expecting this, as I wanted to focus on making the connection work first, and then go for the outbound natting.

I didn't even add a 'policy' firewall rule on my LAN interface to make the connection work.
It's not activated :

So, first things first : Make your connection work.

Btw : this is the file the OpenVPN client is using right now :

You can clearly see de double spaces lines at the bottom, some of them are present twice in the config file.
This is an issue for later, because, with these settings, it works.

@gertjan

That's a real big screenshot. Kudos on spending the time to piece that monstrosity together.

Noticed some differences:

1. The ExpressVPN setup instructions for 2.4.5 say to leave NCP (Negotiable Cryptographic Parameters) blank, but in your 2.5.2 configuration you have it checked (now called "Data Encryption Negotiation").
   

2. The ExpressVPN setup instructions for 2.4.5 say to check "Don't pull routes", but you haven't.
   

But I followed along anyway and replicated your settings. And the gateways are still offline. I haven't adjusted the firewall rules yet. I'm still trying to get these gateways online.

Note: Prior to making these screenshots, I shortened the names of the VPN clients and their interfaces, so they'll appear a little different than in prior screenshots, but they're still the same ones.

• VPN clients online
  

• Gateways offline
  

• Using ExpressVPN's IP address checker:
  

• Interface settings
  

• Gateway settings
  

• Client settings

At this point I'm thinking that the only way forward is for a network expert who's familiar with PfSense and OpenVPN to sit down at my computer and poke around until they can figure out what's going on. Whatever my problem is, it's not normal. I'm not a network expert, and I don't know how to diagnose this. I've replicate other peoples' working settings, and it isn't working on my end. Here's some more diagnostic info; does it give you any ideas about where to start diagnosing next?

• I can tell from a basic Wireshark scan of my network traffic that TCP failure and retransmission is not uncommon, and PfSense's Status -> System Logs -> Gateways shows me that communication with the gateways is frequently timing out. All gateways are timing out, including the WAN, which is what I'm currently using to get online and talk with you.
  
  These are all from this morning:
  

• It's rather frequent that I try to load a web page, wait several seconds, the page fails to load and the browser says that it can't find the page, and then it automatically retries and succeeds (sometimes needs to retry twice). I don't know what is causing this frequent failure, or if there's anything I can do about it. I've got a 100Mbps internet connection over cable that is usually stable and reliable once connection is actually established (ex: a long download or a big YouTube video doesn't fail once it's started). It shouldn't take 5-10sec to load a google search. The failures (when they happen) only occur when initially loading a page. If it were a random hardware failure (circuitry going bad, loose cable, etc.), I'd expect random disconnects during downloads and streaming large video, but I'm not seeing that.
  
  I've mentioned before that when I use the ExpressVPN desktop app to make a VPN connection, all those connection issues for my PC disappear. Web pages load quickly 100% of the time, no timeouts, no lost connections. That makes me wonder if there's some sort of packet monitoring and sniffing going on after the traffic leaves my network that either slows the transmission enough to time out or stops it entirely. Why would making an encrypted tunnel to ExpressVPN's servers magically make the disconnects go away?

• My connection is this: Cable -> modem -> router (mini PC running PfSense 2.4.5) -> TP-Link Archer A7 (wifi router/switch configured as access point only) -> PC.
  
  Here's the TP-Link Archer A7 set in AP mode
  

• The TP-Link Archer A7's DHCP Server is set to Auto, but the DHCP client list is empty, so I'm guessing that it was smart enough to not try to be a DHCP server when in AP mode. Should I explicitly turn that off?
  

Does this info give you any ideas of where I can start diagnosing next?

Any ideas of network diagnostic tools that can help me track down where the traffic is disappearing and why?

@amdreallyfast said in pfsense 2.5.2: ExpressVPN connection working by gateway has 100% packet loss:

but in your 2.5.2 configuration you have it checked (now called "Data Encryption Negotiation").

Because (see above) :

Data Encryption Negotiation - <checked>

It's checked because "openvpn 2.5.2 needs (like mandatory) it.

@amdreallyfast said in pfsense 2.5.2: ExpressVPN connection working by gateway has 100% packet loss:

The ExpressVPN setup instructions for 2.4.5 say to check "Don't pull routes", but you haven't.

?? Correct - both are non checked.
( probably because the server (ExpressVPN) pushed them ).

About the images that show the red 'offine' : use 8.8.8.8 as the monitoring IP : the IP's used (your IPs) do not reply to ping, so there will be a red "offline, even when the connection is online.
This one :

Can't find this one in your images ?

You have pfSense 2.5.2, right ? I can't help you with the old OpenVPN 2.4.8 used by pfSense 2.4.5p1.
The OpenVPN versions used are different. OpenVPN went from 2.4.8 to 2.5.2 Several options changed ( and that is why this subject exists ). Some minor parameter changes were needed to make it work again.

Btw : your AP should be an AP. Nothing else. Don't leave the DHCP server on Auto, shut it down ( off ). ( because : scenario : powerdown -> powerup : IF the AP boots up earlier as pfSense, the AP server will activate - moments later the sense DHCP servers activates : You've created a whole new issue)
The AP is not part of the issue right now. And if doubt, remove the AP from the equation - use a straight cable, as cables are easy to debug ;)

[amdreallyfast]

@gertjan

About the images that show the red 'offine' : use 8.8.8.8 as the monitoring IP

Done.

BTW, the WAN's "Monitor IP" is set to itself. Is that bad? I didn't set it as such, so it must be the default.

You have pfSense 2.5.2, right ?

I downgraded to 2.4.5 (via format -> fresh install) because I've been trying to replicate the conditions that the ExpressVPN setup instructions expect. If I update to 2.5.2, then I won't be able to go back, but since you were able to get ExpressVPN working on 2.5.2, then I hope that the upgrade shouldn't be an issue. I'll do that tonight.

Btw : your AP should be an AP. Nothing else.

Done. Turned it off. At least that's out of the way.

BTW, I'm hesitant to remove the AP entirely because then I won't have wireless. My router box only has to two ethernet ports. I can't run my PC to the router and still have wireless internet. If the issues continue to persist, I'll try doing it. In hindsight, I should have purchased a mini PC with 4 network ports, but I didn't think of that at the time.

[amdreallyfast]

@gertjan

Well, after upgrading to 2.5.2 and explicitly turning my TP-Link DHCP server off (from Auto) and restarting everything, the gateways are now in indefinite "Pending" mode. I'm out of ideas. Yourself?

[Gertjan]

@amdreallyfast

How many Expr*ssVPN clients have you running ?

Concentrate one one, then add others if needed.
I know Expr**sVPN offers 5 ( ?) simulations connections - dono if they accept 5 from the same device.

Now you have 2.5.2, get your client opvn file and post it here. I'll compare yours with mine.

[amdreallyfast]

@gertjan

Alright, I'll disable two of the interfaces and the OpenVPN clients that use them.

While waiting on the gateways to work themselves out, here's my config.ovpn file, unaltered in any way. It looks like upgrading to 2.5.2 changed how the config files were stored, and now I have the file structure that you had expected in prior posts.

[Gertjan]

@amdreallyfast

I compared you opvn file with mine.
There is 1 ( one ) difference :
local 192.168.10.3
for me, as me WAN IP is 192.168.10.3 - I have an up stream ISP router.
You have a 'real' WAN IP 68.100.115.1x9 - That must be the IP of your WAN interface.

You'll see :
comp-lzo adaptive
and then
comp-lzo
in the custom option box.

The latter cancels / modifies the first, I guess.

Do not forget to add the ";".

Now, when I remove the check from 'disable' at the top, and "save" I have these logs :
Logs are in reverse order : the connection sequence starts at the bottom :

Noticing AUTH_FAILED. That's clearly bad.

@amdreallyfast said in pfsense 2.5.2: ExpressVPN connection working by gateway has 100% packet loss:

This is just one AUTH_FAILED cycle

That's a matter of copying correctly your credentials.
Was this message there all the time ?
This is the most logical reason the connection doesn't come up : your bank site won't let you in neither with wrong credentials..

This issue wasn't worth mentioning, as it is easy to correct.

edit : in the folder where you found the opvn client file, you will also find a file called 'up'.
Open it ;)
This explains this setting :

auth-user-pass /var/etc/openvpn/client1/up

When the login is transmitted, and it's wrong, the "PUSH_REQUEST" will not receive the route, gateway, IP etc but an error message : you saw it.
The gateway isn't reachable, as you failed authentication.
When the "auth" went well, you receive a

PUSH: Received control message: 'PUSH_REPLY,redirect-gateway def1,dhcp-option DNS 10.46.0.1,comp-lzo no,route 10.46.0.1,topology net30,ping 10,ping-restart 60,ifconfig 10.46.0.134 10.46.0.133,peer-id 56,cipher AES-256-GCM'

and as you can see, the gateway, amongst others, is in there. pfSense uses all this info to set up everything.

Looks like it's working now. The auth problem was caused by an old username/password that went bad when the subscription recently expired. I just renewed it, entered the new username/password, and now the gateway is online.

Then I enabled the firewall rules and firewall NAT -> Outbound routing rules, and it looks like its my San Francisco VPN is now working and routing traffic correctly. I'm writing this post while my router is connected to the new VPN.

It looks like your settings worked for me too. I remember deviating from the ExpressVPN setup instructions in the VPN client setup by checking Enable NCP (2.4.5; on 2.5.2 it's called "Enable Data Encryption Negotiation") and by unchecking Don't pull routes", and by unchecking both Interfaces -> <vpn interface name> -> Reserved Networks -> Block private networks and loopback addresses and Block bogon networks. And I think that I edited the manual custom configuration options a bit so that they match yours. Current settings.

comp-lzo;

Thanks for all the patience. Next I'll need to figure out custom routing rules for connections that don't like the VPN. Some places block it and I'll need to make exceptions for those.

@amdreallyfast
Sit back, and think with me :
What is different between these 'famous' Exprr*VPN instructions, and the ones needed to make VPN works with 2.5.2.
You'll agree with me : it's not much. Re see the post about this subject I made several month ( ? ) ago.
I'll have a look at it this weekend.

@gertjan

You'll agree with me : it's not much.

True. The problem is that network software rarely settles for "close enough". Figuring out exactly what I needed to change was the rough part.

And now, curiously enough, the docs pages for pfsense won't load. It's like my firewall (or maybe theirs) is blocking me. Back to the non-VPN configuration while I try to figure out how to pass traffic for certain websites through the non-VPN connection.

I had expressvpn running on 2.5.2 but it was very slow (SFO from Okinawa, Japan) also I could not change from SFO with ease. I finally installed expressvpn firmware on old external router. Tried to connect via pfsense vlan, many times, finally expressvpn help desk told me that expressvpn would not work via a vlan. Reinstalled pfsense, reinistalled pfblocker. Changed to opt1_dmz, configured new gateway and added new static address. Than I changed router from PPPoE to DHCP and expressvpn worked fine, in fact speed testing is as fast as non-vpn speeds and all expressvpn options are available. I use expressvpn for USA paid networks (prime, netflix, etc.) via wifi inside the house. wifi from expressvpn router. Your luck may be different. elmo

@Gertjan

Thank you, the monitor IP (8.8.8.8) and compression is what I needed to make mine work!
