Argh! yet another obstacle from my ignorance. We are attempting ingress
traffic shaping using IFB interfaces on traffic coming via GRE / IPSec.
Filters and hash tables are working fine with plain GRE including
stripping the header. We even got the ematch filter working so that the
ESP packets are

Hello, all. I understand there is no direct way to negate a u32 match.
I have a setup where I am redirecting all ingress traffic from the
physical interface to an ifb interface with a u32 match u8 0 0 action
mirred egress redirect filter attached to :
I do not want to send ingress ESP packets

Hello, all. One one of our connections we are doing intensive traffic
shaping with tc. We are using ifb interfaces for shaping ingress
traffic and we also use ifb interfaces for egress so that we can apply
the same set of rules to multiple interfaces (e.g., tun and eth
interfaces operating on the

Hello, all. We are seeing TX abort errors on all of our GRE tunnels.
What would cause such a thing? We suspected it might be MTU because
these are encapsulated in IPSec transport and the MTU on the GRE tunnel
is still 1476 so we reduced the MTU but that did not eliminate the
problem.
By the way,
Hello, all. I hope this is the correct list for this question. We are
having serious problems on high BDP networks using GRE tunnels. Our
traces show it to be a TCP Window problem. When we test without GRE,
throughput is wire speed and traces show the window size to be 16MB
which is what we con
