[LARTC] IMQ and GRE

[LARTC] IMQ and GRE

[Alexey Talikov]

This question mainly for Patrick McHardy
As I understand problem about IMQ and GRE all been working fine, if I send packets from tunnel
to another IMQ. I'm right ?

My configuration
eth2 - main link
ppp0 - PPTP (tcp control connection on port 1723-over eth2 and GRE tunnel ppp0 )
I'm not sure that only GRE packets flowing through ppp0, can somebody corect me if not so ?

modprobe imq numdevs=2
..... ( queue config for imq0 and imq1 )
iptables -t mangle -A PREROUTING -i eth2 -j IMQ --todev 0
iptables -t mangle -A PREROUTING -i ppp0 -j IMQ --todev 1
ip link set imq0 up
ip link set imq1 up

Thank for any answer !!

right. the problem is when sending packets to a device which 
encapsulates them and both the non-encapsulated and the encapsulated go 
to the same imq device.

hmm sorry i don't really get your configuration. gre tunnel is going 
through ppp0 which is pptp over eth2 ?
you can just try out if it works, your computer won't crash if it 
doesn't. you'll see some messages about
imq beeing deadlooped in the ringbuffer if it doesn't ...

Bye
Patrick
