I can not install multiple simultaneous PPTP session

RouterOS General
1

HI,
RB751, OS 6.5, set up PPTP server, Only One - NO.
I can not install multiple simultaneous PPTP session with a single external address. The first connection is successful, subsequent connections freeze on the authentication step and fall off with an error 721. Can you please tell why. Thank you.

Hi,

Error 721 is GRE related: GRE packets cannot reach destination. I ran in similar problems trying to redirect the PPTP ports. Since I use OpenVPN, everything works pretty well.

If you habe to stick to PPTP investigate why GRE cannot pass.
