Hi,
I've a gateway host (cali), connected to the Internet via ADSL and a PPTP tunnel
(ppp0). I also have a IPIP tunnel to another host over the Internet (mytun),
nothing fancy.
This is working perfectly.
But I want to give more priority to the IPIP packets coming OUT of the PPP (PPTP
connection) interface. And I can't get this to work.
Class 2:21 is the one with high priority.
FILTERS:
filter parent 2: protocol ip pref 1 fw
filter parent 2: protocol ip pref 1 fw handle 0x1 classid 2:21
CLASS Stats:
class htb 2:21 parent 2:1 prio 1 rate 96Kbit ceil 128Kbit burst 1721b cburst
1762b
Sent 0 bytes 0 pkts (dropped 0, overlimits 0)
lended: 0 borrowed: 0 giants: 0
tokens: 218962 ctokens: 168131
As you can see no packets have gone out of this class.
IPTABLES RULES (mangle table):
Chain OUTPUT (policy ACCEPT 794K packets, 111M bytes)
pkts bytes target prot opt in out source destination
4984 377K mark.4 4 -- * * 0.0.0.0/0 0.0.0.0/0
Chain mark.4 (1 references)
pkts bytes target prot opt in out source destination
4984 377K MARK all -- * * 0.0.0.0/0 0.0.0.0/0
MARK set 0x1
But you can see that iptables is marking the packets correctly (the counters
were reset at the same time).
So, I'm guessing that the IPIP packets generated by the kernel, are not going
into the packet scheduling routines/functions.
If someone can point me to the place where this should be occurring, it will be
great.
I'm using Kernel 2.6.9 (2.6.8 did the same thing).
Thanks.
Javier
