How to bleed PPTP sessions

Does anyone have a way we can cause a router to stop taking PPTP sessions without interrupting running sessions?

I need to be able to bleed sessions off so I can do maintenance.

It should be enough to stop accepting new connections on TCP port 1723 without destroying the existing ones. I don’t know how your firewall filter rules look like, but

/ip firewall filter print where dynamic=no chain=input
/ip firewall filter add chain=input protocol=tcp dst-port=1723 connection-state=new action=drop place-before=0

should work for any firewall setup.

Cheers thanks .. that makes sense. I’ll give it a shot.
