Hello,
If two companies want to be connected to each other, is OpenVPN a good solution? Is it stable?

Thank you.

Why don't you try it instead of asking these inane questions? There is no way anyone can even answer that question as asked, since one company's requirements maybe very different to another company's requirements.

More generally speaking, there is a wonderful invention called "search engines", you should try actually using them.

Here's a demo:

I did, but I need users opinions that used it.

...and....
Why do you 'need' someone elses opinion about it? Again, your question cannot be answered, because it lacks any context or details, much like several of your other threads. Because "two companies" can be two small businesses, or two huge corporations, not to mention the user load, available hardware, available network bandwidth, among the other ton of things that factor in.

You right about some of these.
Consider two big companies with some Cisco 2960 switches and a bandwidth about 1Gbp. Clients want to copy and move files about 1GB.

Ok. Consider thinking about the problem more:

• How often does this get transferred?
• How many users (again) are doing this?
• How many CONCURRENT users?
• Is that bandwidth dedicated to VPN, or shared?
• They're 'big companies'....won't they already have a mechanism in place to share files?
• ...and a TON of other considerations.

Again, your question lacks any details that would let anyone answer. A lot of large companies use OpenVPN, but asking if it's 'enterprise' is far too open ended to have an answer.

I worked at a place hosting servers and supporting them, and customers use OpenVPN to connect to their business partners all the time. In the past they have had issues coping large files, but I think was due to connections dropping and/or the system downloading things not able to handle the large file size.
Also there is bandwidth charges to consider, so it turned out to be more cost effective to ship an encrypted USB drive.

The enterprise version for OpenVPN, called Access Server, in the past could be downloaded for free and used but with only 2 user sessions active at a time. Not sure if that is still the case. The open source version has no limits, except it does not have the web interface so all configuration is on the command line.

OpenVPN can be used to connect 2 remote sites. Is it a good solutions? Depends. Is it stable? Depends.

Pretty much the same way some routers have VPN features. IE: Mikrotik or a Linux box being used for site-to-site connectivity. Are they good enough? depends on the requirement. Are they stable? Depends on what it is being used for.

Lots of factors to consider.

Normally you would get a list from a client or employer of what is expected of the system and the budget constraints and work from there.

Thank you for share your experiences.
The dropping problems was because of their devices and not OpenVPN itself?

Thank you.
1- Their copying files almost always.
2- About 100 users.
3- About 30 users.
4- Dedicated to VPN.
5- They have a file server, but these companies are far apart.

Did you read the entire post?
So *AGAIN*

• 'Copying files almost always' means what?? How BIG are the files, and how do you know?
• 100 users copy files all day, or....
• ...30 users copy files? Which is it?
• What does 'Dedicated to VPN' mean??
• And it's hard to believe that for two locations they don't have two file-servers...even harder to believe that they don't ALREADY have a connectivity solution in place.

You still haven't said what kind of bandwidth they have, which factors hugely into suggesting a correct solution.

Then they need to pay for an business-class, supported solution. And they need to have it installed/configured by their admins, who know what they're doing. This is sounding either like a homework question, or you are trying to get a job putting this in, and you don't know what you're doing.
