Hi,
not sure if this is advanced enough, even though it does concern business/industrial network.
We have issues with some connections to PLC's of industrial machines when connected over VPN. Seems like the PLC's start to actively drop connections (monitored via Wireshark) when ping is a bit higher than 50-70ms. Considering that some of them are sitting on a temporary 4G connection, that is quite an issue.
This happens when using a programming software which really is designed to have a local LAN connection to the machine. Manufacturer says, that some clients do use VPN's successfully, but community says that issues on high ping connections are normal.
Is there a way of buffering packets on purpose, so I can test this behaviour when physically at the machine? Or does this smell like changing source code of say OpenWRT to introduce an adjustable delay FIFO buffer?
Thanks!
