[Solved] Slow speed ONLY via home router connection

Post by gudetuxir » Mon Jul 03, 2017 2:29 pm

Howdy,

I have an OVH vps service with OpenVPN fine configured (3 laptops, 2 mobile phones, and a desktop): each different easy-rsa crt/key generated.

For last 9 months everything has been working fine. Problems got started after replacing my home router. For first few days, everything worked fine. Then suddenly (after upgrading OpenVPN at the Linux server), it all started.

Funny thing is, the OpenVPN server for other connections (not via my home router) work fine (full speed) - the problem occurs ONLY when I'm trying to connect via home router. Furhtermore, when I switched back to an old router it didn't helped, it's still screwed up.
(btw. I have my OpenVPN configured on each client separetly, not on the router; the home router is only the ISP gateway. it's pretty same configured as the previous one, nothing fancy is going on here)

And the problem is: downloading speed is about up to 100 kb/s at max (usually, 50-100).

I have tried many things, and nothing helped, thus I'm forced to ask here for help.

The new router is TP-Link TL-WR740N v4.23 (firmware: DD-WRT v24-sp2), but I'm pretty sure it's not the problem source since on the previous router it still sucks (when I'm switched back -- and it worked all fine eariler :roll: ).


What I tried (none of follows work):

- changing DHCP on my client (on the old router it was 192.168.1.5, now it is 192.168.1.69),
- generating new easy-rsa crt/key files for the client,
- modyfing server.conf in every possible manner (udp/tcp, tun/tap, different ports, different ciphers, LZO comp on/off, and so on...).

The speed is always the same LOW. When I connect my device via 3G the speed is maximum, and via the home router - it never exceeds 100 kb/s. Everything works pretty fine, but not on my home router (before replacing router it worked at max speed either).

Although I'm very familiar with Linux, I'm not OpenVPN expert, so perhaps someone more experienced can help me out here.


My config is as follows:

(and I'm pretty sure it is all well configured, since it has been working for last 9 months -- and also, for other connections (but via my home router) it still works really fine - with max speed)


I used this tutorial (about 9 months ago):
https://www.digitalocean.com/community/ ... n-debian-8

I have Debian 8.8 on my server (VPS).

You can get fully up to date version (2.4.x) here:
https://community.openvpn.net/openvpn/w ... twareRepos

But be aware, 2.4 is considerably different to 2.3 with such things as negotiating ciphers ..
There will be a lot to read.

Set --verb 4 and check your server and client logs (best to post them here, sanitized), Please see:
HOWTO: Request Help ! {2}

Perhaps there is something wrong with your internet connection itself.

TinCanTech, thx for posting.

If nothing will help, I'll try with upgrading to 2.4.x (I prefer rather staying with default Debian 2.3 version, for now)


I'm posting logs from openvpn.log (verb at level 4)

btw. this MULTI: bad source address from client..., at the end of log file is nothing wrong (I've checked, and it occurs on every device: even those, which work on full speed); the low speed problem occurs only when connecting via the home router.



Do You see anything suspicious here?

Nothing suspicious at all .. although sndbuf/rcvbuf will default to the OS default, unless you know you need to change it, you probably don't need to set it.

Because you only have a problem with one site (your home) and the problem only arose since changing the router (and changing back does not resolve it), I would be inclined to contact your ISP and report a fault.
(Perhaps they are throttling your VPN)
:roll:

This can be safely ignored for now.

It is due to packets from the client passing over the VPN having your client eth0 IP (eg. 192.168.x.x) and not the tun0 IP (eg. 10.8.x.x), you can configure the server to learn those addresses with --client-config-dir.

I've just called ISP support, and the tech-guy explained me that there is no problem on their side. ehh... :?

ok, it seems I'm forced to upgrade to 2.4.3 [unstable], we'll see...

Re: Slow speed ONLY via home router connection

Post by gudetuxir » Mon Jul 03, 2017 8:44 pm

ehh... after fighting many hours, I failed.

I upgraded OpenVPN to latest version (2.4.3, unstable @ Debian 64-bit):

Code: Select all

# openvpn --version
OpenVPN 2.4.3 x86_64-pc-linux-gnu [SSL (OpenSSL)] [LZO] [LZ4] [EPOLL] [PKCS11] [MH/PKTINFO] [AEAD] built on Jun 30 2017

...I even tried another VPS (from different provider, not OVH): I made fast setup, and... and the same thing. 100kbps is the maximum speed I achieve.


so I give up... I have no idea what is going on... ISP is saying that it is not their fault, and there is nothing they can do.

it is the router, there must be some setting I configured that is making mess here. everything works perfectly fine, but not via my router (or the previous one) -- and eariler it worked all fine... why did I touch it!?!?!?


ehh... so this is the end... there is no solution for that...


Regards all,

RIP.

Can you download a large file from the internet (eg. Debian ISO) ?
from your home (with the dodgy router) ?
if so what speed do you get (without openvpn) ?

TinCanTech, I can download large files from internet (everything works pretty fine). Without OpenVPN (directly) it goes max (~1,90 MB/s).

Only when using VPN it slows down to mentioned 50-100 kbps. I also tested drectly connection (with FTP) to the VPS: it goes max up / down.

I'm reading dd-wrt docs right now, but there is not many options to play with...

and btw. it looks like there is some throttling up there... because when I'm starting to download a file, it starts with high speed (not max, but about 40-50% of max speed, then it goes down to 50-100 kbps within seconds).

Re: Slow speed ONLY via home router connection

The openvpn config and log file from one of your clients (behind the dodgy router)
might be of some assistance at --verb 4

If :
(1) your router is simply being a router/modem and not doing any encryption/decryption
(2) and all the clients behind only that router have the same problem when using openvpn
(3) and you don't have any other problems related to speed from that site
(4) and your ISP will not help because you are not using their equipment

then
(4) put their equipment back in and try again (but I know you even tried that). :x

However,
I see you have changed the openvpn port to 1193 (I was going to suggest that)
UDP is always faster that TCP but you could try --proto tcp --port 443 (https)
(Just in case your ISP is trying to throttle you .. )
And, as a last resort, you could try --mtu-test in one of your problem clients.
Post that client's config and log once --mtu-test completes.

TinCanTech... I'm out of words at the moment... I don't know what to say, I'm totally shocked...


the thing is... everything works now fine (at full speed -- I mean, the OpenVPN)

I changed to:
- port: 443 (HTTPS),
- proto: TCP (so it's the same as "regular" website visitation... my ISP blocks VPN and they said they DO NOT, when I was calling their support... this is crazy... One more question: is it possible that they are doing it deliberately (intentionally) or this is my fault, because I messed up with router?

I'm asking, because my ISP is one of the biggest in my country, and I'll make a BIG CRAZY shit-storm over social media about that -- therefore, just askin' :mrgreen:


and btw. PM me Your BTC wallet, I'll send You some $$ for a beer for helping me out!


BIG THANKS!!!! :)
