Good morning
I was advised by my IT department that Iburst allocates bandwidth from the lowest category to VPN. Is this true and is there no way it can be allocated a higher priority/amount of bandwidth?
Thanks in advance
 
Not sure if it is true....

I successfully use OpenVPN to connect to various networks without any issues, providing that iBurst is not experiencing any issues, with towers etc.
 
Not convinced

I would hope it's faster than 3G or edge, Iburst's connection speed is supposed to be almost double as fast. However, HSDPA users at work do not experience the same connection speed issues as I do. Especially using outlook on my desktop, connected to VPN, it's very slow. My connection speed is considerably slower than when I had ADSL 512k, doing the same thing with the same hardware. I have a constant 8/10 tower strength as indicated by utTracestar.
 
We use VNC on iBurst, while slow it have an constant transfer rate so you can work at least without worrying about a dropped line.

Slow... Latency issues - both on VPN & Skype calls

Completely dependent on your connection. It has a limit because of the higher latency nature of wireless, but you can use Skype easily with an okay connection.

If it is true that they allocate lower level bandwidth to VPN, then it might be slow. Where did your IT people hear this btw Theo, I doubt they can know this for fact unless they actually hear it from iBurst or are they just assuming because VPN seems slow? I guess it is possible..
 
Reply from Iburst

The IT guys apparently spoke to Iburst directly as there are a few guys that use Iburst to work from home via VPN.
I received a reply from Ed Hall and I quote:
"Hi Theo
Thanks for the mail. I will take this up with our technical team, but we don’t shape VPN, however having said that it does not recieve priority.
Regards
Ed
"
Let's hope I get some joy, but so far getting a response is quite positive!

Lol, seems to be a contradiction :p Port prioritisation or Port shaping..

Well if it isn't "shaped" in iBursts eyes it means they don't throttle it to 64kb (or at least thats how it used to work) so it is capable of going above 64kb, but obviously wont go as high as normal usage.
 
Hi Guys, the statement is taken out of context....Theo asked if we can prioritise VPN, answer is we don't shape, therefore no prioritisation....doesn't make sense for us to throttle VPN.

However, as Ekhaatvensters says, it won't go higher than normal usuge and this is key. So if db readings are good, the quality of the VPN connection will be good too.

Not true ... I have excellent signal and quality, below 80ms latency, downloads at between 100KB/s and 120KB/s and we've been running a VPN connection from home since last year March, and on that VPN never EVER got above 100kb/s
 
Try enabling the compression

Hi LM

I am using Open VPN, and I enabled the compression and changed the MTU from the suggested 1324 (VPN usage) to 1352 and it is now far more responsive than before.

Not sure if you have tweaked your settings, but this was of benefit to me, however when the access speed drops below the 300kbps mark it becomes unusable.

This is a corporate VPN connection ... cant really change anything as the settings are set up by them
