Working from home I connect through a VPN to the VPN server of the office configured on top of ClearOS.
From home I can ping all the office except the Compact Rio.
If I connect to my office workstation with remote desktop, then locally I can ping all the office, including the Compact Rio. So it's online and responding.
What can make the CRio to respond to ping requests only from local mates and ignore my home computer through the VPN? What's the difference if connecting through VPN is the same as being locally?
Thanks for your time,
[Disclaimer: Networking is not my forte, but I'm happy to share my experience]
I also work with VPN and cRIO devices across the network (both using remote desktop to a local machine, as well as from my home computer). I have not had problems pinging the devices when remotely. Some things that might be worth considering:
All that being said, I think your IT support is the best bet to get this solved. You can find the common ports used by NI software here: Configuring Software and Hardware Firewalls to Support National Instruments Products
All the best,
Sorry for my late response:
1. To the company's network
2. From home I can ping my workstation at 192.168.100.26 and another computer at 192.168.100.33 but I can't ping CRio at 192.168.100.32. So you can see that is the same IP type & range. Our IT service isn't blocking anything because we don't have one 😄 We are a very little company. And yes, locally in the office I can ping the CRio.
3. MAX doesn't detect anything even directly writting the CRio IP because it is inaccesible from VPN due to some obscure reason.
Interesting, I've never seen that specific situation with our VPN. 🤔
I guess that depending on how the VPN and internal network are setup, they will require of different settings to "make then visible". Some other ideas I can think about:
All the best,
I've had some issues with VPN on our corporate network as well. I don't have the same situation as you do but maybe the same solution will work. I've been forcing the connection to my cRIO by adding the route to go through a certain network interface on the computer. To do this you need to open a command window as administrator and use the command:
add 192.168.100.32 mask 255.255.255.255 192.168.100.1
You might need to figure out what the red IP address should be, it should be whatever the VPN is using as a network adapter. Ours creates a virtual network adapter but you should be able to figure that out with ipconfig /all or going into your adapter settings.
1. VPN is in company's router. So if you connect to the company VPN you can reach the whole (and unique) company LAN (192.168.100.x)
2. Static. And gateway and mask are ok, I have rechecked. But I have the two ethernet ports configured as static. The primary with 192.168.3.3 (for client applications) and 192.168.100.32 for office. But this shoudn't be a problem
3. We are our own VPN provider. It is configured on clearOS. (Operative system oriented to work as router)
add isn't recognized as internal or external command...
Anyway I can access ALL the other VPN IP's. So I don't know why this one should be different. It seems something from the own CRio... Because all the other things work good when CRio isn't present.
Thanks for your time guys!
My apologies, forgot to add the most important part at the beginning, should be:
route add 192.168.100.32 mask 255.255.255.255 192.168.100.1
I have exactly the same issue.
Trying with "route add" does not make any difference.
Have you been able to solve the problem? How?
