RV260 and PPTP fails

[Tom39347]

I've recently purchased a Cisco RV260 and tried to setup a PPTP to access the network remotely. I'm getting the following error when trying to connect. It appears this has been an issue with the with the RV340 & RV260 as well. Has anyone found a solution? Or am I missing something?

Looks like known issue, open a Cisco TAC case with SMB
