Recently, we started having an issue with Mac users being able to print through the ssl-vpn tunnel.
If the Mac is inside the Lan and connects to a windows 10 workstation via MS RD v. 10.3.4, printing a test print to redirected printer only takes seconds. if I move the mac outside of the lan and connect using the SonicWall mobile connect client to tunnel in, that same test print takes anywhere from 7 to 12 minutes. Windows clients do not experience this delay.
looking at the logs in CUPS, I see a 0k job with "unknown" pages cancelled, then the actual print job completing about 7 minutes later.
does anyone have an idea what could be causing the delay?
