Support for Multipath TCP (MPTCP)
0%
Description
Hi,
i have read a lot of articles about MPTCP recently. So I wondered why the best router OS pfsense is not supporting it. Perhaps none of the developers knows about it? Or FreeBSD is not supporting it? However, for FreeBSD there seems to be some kind of support:
But what does MPTCP: It bundles diffent network connections of the tcp layer, so the application can use multiple (internet) connections without even knowing it.
https://tools.ietf.org/html/rfc6182
https://tools.ietf.org/html/rfc6824
Why is it so important for me: Well it supports some scenarios which pfsense tries to support i.e. with apinger etc. in a much "better" way: Gateway failover, utilising multiple internet connections in the tcp session!
IF YOU COULD ADD THIS FEATURE, IT IS POSSIBLE TO BUILD SYSTEMS LIKE THESE: http://www.viprinet.com
Even IOS supports it for Siri!
Kind regards and i would love to see this feature!

Viprnet is just bonding, not mtcp.
When mtcp shows up in FreeBSD base (not as a side-project), we'll make this work.

Hello,
Could you please add this feature on 2.4.0 version?

I also would like to see it in PfSense.
I'm using MPTCP to bond my three connections (2x VDSL + LTE). It works perfectly! But of course I have to use a minimal linux system with iptables without any graphical interface or something and I really would like to switch back to PfSense :).

Well, I guess there's no further development right now. Last commit was 2019-12-12.
I couldn't find any hint if something was implemented in FreeBSD.

Telekom has started offering MTCP in Germany, and given the abysmal situation with broadband in the country we would be very happy if we could use this feature with pfSense...
