Bridge two networks using mlppp pptp and bcp bridging

Has anyone else had issues in version 5RC5-10 getting BCP bridging with mlppp(mrru 1600-65535) working with an underlying pptp tunnel.

I get it to connect though cant send full packets through i.e. 1500 ping x.x.x.x -l 1460 -f and the packet just goes missing?

I can get this to work when I use sstp instead of pptp though this isn’t really suitable for this task.

I followed Butch Evans example over at:

I haven’t got any v4.x systems to test with, can anyone replicate this problem?

have you got this working?
I still have the same issue with pptp but it works with only with sstp
