[Share your knowledge] ❓ OVH Game & GRE Tunnel ❓

Hi, there!
I'm Florin, one of the owners of https://hazi.ro.
I would like to talk with those who have experience with OVH dedicated servers & GRE tunnels having OVH at one end.
My question is: Did you had network issues for tunneled traffic? If yes, how did you solved them?
For me, the difference is so huge as I download directly something with 10Mbps and with tunneled IP only 500Kbps (same source).
Any feedback is welcome!
Best regards, Florin.
One more thing:
Moved tunnel from OVH Germany -> Romania to OVH Germany -> OVH France and got exactly same result.

It is OVH and tunneled traffic, you don't fix it.
Thank you for reply!
Unfortunatelly OVH can't confirm this but having this issue everywhere is an important point.
Their reply on my request related to this fact:
OVHs VAC will pickup that traffic super quickly and rate-limit or even block it outright. VAC does not respect firewall rules either when it comes to "mitigating attacks"... often GRE gets dropped entirely for many people.
does buyvm support such protocol/service? maybe they can help idk
Thank you for feedback!
This could be a good starting point but as far I know, they don't filter internal traffic and this issue is active also when I have OVH servers on both ends.
Best regards, Florin.
I'm sorry for that I didn't understood that it is impossible to be fixed and I've played again with it.
In my opinion one-way is already fixed (500Mbps Deutschland - Romania) is quite good.
Next I'll have to discover why it is so bad during download
check that the interface is with the correct mtu (1476 for the classic gre).
Thank you for feedback!
Is still hard to figure out what's wrong.
Here's IPIP tunnel with 1454 mtu:
and here is GRE tunnel with 1476 mtu:
Both setups have 1428 as mss value.
Best regards, Florin.
Try using different IP's.
What you mean?
You use one IP for ingress and another one for egress.
Also, regarding the 500Kbps, it makes sense, the client usually does not send that much, even if you got 2-3 clients per IP.
AntiDDoS applies only external, maybe worth trying forwarding it through another OVH box without Game AntiDDoS and forwarding from there.
Unfortunately both boxes I have on OVH are on GAME range.
I've bypassed few kbps limit but still 30% of total network speed isn't cool.
Best regards, Florin.
Get a Kimsufi, test it, they used to be very cheap.
Otherwise just get a OVH VPS I guess.
Kimsufi & VPS servers are not suitable because my goal is to forward IPs from OVH to Romania and Kimsufi has only 1 IP address and VPS has max. 16, still useless.
Best regards, Florin.
I don't know if this can help but it can be a test.
In the anti ddos protection control panel, try to whitelist the ipv4 of the server in romania.
Did it with v4 and GRE protocols, nothing changed.

Hello!
As far I remember, I've discussed with some LET providers which said that they have succeed to solve GRE bottleneck using OVH support system.
May I have a DM from one of them to talk about this?
Thank you!
Tunnel through Kimsufi?
Kimsufi acts as a router for the OVH IPs.
From OVH point of view, GRE traffic comes from Kimsufi, so that it doesn't trigger DDoS alert.
How many push-ups you did to discover my secret plan?
You're unbelievable !
How many push-ups will you do in my honor for finding this solution?
You're incredible!
I'll do all of them, you deserve this
Once you got the solution working, will you contribute a push-up video for broadcast on https://pushups.ndn.today ?
i will not use GRE
bandwidth eater
vps suspender
What you mean regarding "VPS suspender"?
i had my vps suspended with a provider some years ago because of GRE, it consumed 1T25GB just overnight and had reached my monthly limit.
once burned, never again.
GRE doesn't affect amount of traffic consumed, so that could happen also without any tunnel behind. Single thing involved is that you consume bandwidth at two ends at the same time, but not double bandwidth on same host.
Don't say that again.
Keep in mind I've realised 2 months ago that thing I can't do even a push-up.
Count those 5 as 50 because for a while I'm an indoor man.
