What kind of bandwidth do you have now?

by robo_dev In reply to VPN Bandwith

Typically you pay more money to get a faster link.

Great! Run netflix and about 7 computer and 1 domain controller at home and no lag in speed, i use OPEN DNS as my dns server so i can filter websites out... malware sites ect.

Another Option

by RaymondJM4 In reply to VPN Bandwith

If I???m understanding the question correctly, the more secure your VPN tunnel, the slower it will be. With that said, you can either reduce the security (only encrypt the data or the connection but not both ??? Not recommended!!), or you can simply setup a remote desktop connection on a spare computer. That way whomever is on the remote side of the data could simply remote into the spare computer. Both of you could even use it as a calibration station where you would both use remote desktop to connect to the data regardless of the proximity to the data. This would also have the added effect of ensuring only one person is editing the data at a time. Another option would be to use a better packaging method for compressing and transporting the file. I???m assuming you???re not sending it in raw uncompressed format over the VPN tunnel are you? Remember that each item gets encrypted from beginning to end, so the more pieces sent, the slower the VPN traffic. Try sending one big file and not smaller pieces.
In short, I would personally keep the tunnel as it is and setup a collaboration station on one side.

Bottleneck or Bandwidth

by RaymondJM4 In reply to VPN Bandwith

From what your showing me, I think your looking at more of a bottleneck, nthan a bandwidth problem. VPN tunnels are extreamly processor intensive. If your using one server as a domain controller, VPN gateway, and file server, It better be a monster of a device. I would recommend buying a dedicated VPN device like sonicwall. These devices have processors dedicated to nothing but encrypting and decrypting. It also sounds like you have more than one person that your collaberating with. Again, I think your having a problem with hardware and not bandwidth. As far as bandwidth, their isn't much you can do other than buy a bigger pipe. Your downlaod speed isn't what you should be looking at, it's the upload speed at both ends. Home connections tend to max out at 512K -1M.. Anything above that and your looking at a business package.

Personally, I run the Adito OpenVPN service on a Windows XP virtual machine on a VMware ESX server. This gives me enough throughput to view live video over the VPN link, although at a somewhat slow frame rate. This is a SSL-VPN that uses a web browser for the client.

The bottleneck for a home broadband connection is the upload speed. While I get 12 MBS download speed, my upload (outbound) speed is around 1 MBS.

As mentioned above, a dedicated VPN device will be much much faster. Cisco, for example, makes their ASA line of router/firewalls that include a SSL VPN (clientless).

Yes, that sounds like what i have.. ill have to look into a dedicated vpn service, but what i dont get i have a relative that lives what like 2 miles away from me and we rdp into eachothers network via the vpn and that seems to work great fast file copy im thinking its the relative in the bigger city thats has the speed issues due to the large ammount of people.

It all depends what Internet service is being used.

by robo_dev In reply to VPN Bandwith

Regardless of where it is, some connection upload speeds are faster and more consistent than others.

For example, DSL circuits tend to deliver exactly the upload speed advertised, but if you signed up for a circuit that only has 256MBS or 512MBS upload speed, that's what you get.

For cable modem service, it's not uncommon to have a circuit with a 5MBS download speed and an 'advertised' upload speed of 512 kbps or 1MBS, and a 'real world' upload speed as low as 150 kbps.

Cable modem is a shared medium in that the bandwidth is shared with others on the local node, which would typically be something like 100 or up to 200 other people. If these other users are hosting websites or game-addicts, the lower amount of upstream bandwidth will be used up, thus upload speeds will suffer, big time.

Of course if satellite is your ISP, your TOP upload speed is typically 128KPBS
