I have a RB850Gx2 dual core routerboard running v6.40.4 acting as the PPTP server while 8 RB750s acting as the client. Clients connect fine and everything works until I turn compression from default to on. Clients all have compresssion turned to on. I start receiving CCP lost compression got out of sync - disabling compression as well as 17: encryption got out of sync - disabling error messages.

In other words I cannot use compression on the PPTP links. I need to have this feature to save bandwidth. Any idea why? This bug was supposed to be fixed in 6.30 but somehow I'm still getting it on v6.40.4 on my RB850Gx2. Maybe it's because the board is multi-cpu? Please help!

BTW these pptp links are all bridged.

anyone?

And this only happens with compression turned ON and encryption turned OFF

I think compression sync loss is caused by packet loss.
