Sniffer cures packetloss [fasttrack problem?]

Fri Aug 05, 2016 9:33 pm

Hello everyone,

I am using a RB3011 with 6.36rc12.

Somehow starting the sniffer cures my problems with a PPTP connection (only two clients connect with packet_mark and route)
I read somewhere that this could happen because the sniffer turns off the fasttrack.
Although, I'm not sure how to set the firewall to make these connections work correctly?




If someone is familiarized with how to fix this issue, please let me know!
Regards.

If that port is part of a bridge try disabling it in the bridge settings....

/interface bridge settings> set allow-fast-path=no

I guess this fixes the problem ! :D
Thanks a lot!!


Question:
The fasttrack keeps active for any traffic coming from the outside right? Only ignored inside the bridge-local ?

Would it be possible to keep it enabled but filtered with some kind of firewall rule only for this pptp connection traffic?
I'm asking this since most traffic coming from the Internet to the LAN will go through the bridge-local, and so it would "accelerate" this traffic and also release CPU load?

AFAIK fast-path is so the traffic bypasses the firewall already, so not sure it's possible to keep it enabled, but still control it with a rule that it will bypass anyways...

I'm still learning myself, so my knowledge is fairly limited.

Also, I think you may be confusing Fasttrack with Fastpath
