Hello all,
I've recently setup a new plant the company I work for bought. Theres currently 2 DSL lines (internet) coming into the building, they appear to be 4mbit each. I setup 2 linux boxes to act as the edge devices and hooked a dsl line up to each. I setup pptp vpn on each device and hooked them both back into our network via vpn. I setup some routing to put all high priority traffic over one link (ERP System), and low priority over the other (everything else). Our ERP system is located on our main network, so anyone at this branch office connecting to it is going over the vpn links I setup.
Now my problem is, we have datamax label printers out on the plant floor, and our ERP system prints labels to them. Seemingly randomly throughout the day the labels stop printing, if you wait up to 15 minutes, they seem to print. If you restart the printer, they print. If you look on the windows server that our ERP system is running on, you see "Error Printing", I couldn't find anything in the event logs on this.
We have this exact same setup (minus the vpn) at our other locations and it works fine. It seems to me it would be something wrong with the label printer, but after 3 calls, datamax assures me it is not, so that just leaves me with the vpn.
I did make sure I could ping the label printer from the ERP server with a packet size of 1500, it did that without problem, I can't think of what else to try. Anyone have any ideas?
