[mpls-linux-general] Problems using libipq/QUEUE with MPLS

[Mohammad R. S. <sa...@cc...>]

I am having problems running libipq/ QUEUE with ur MPLS implementation. My 
libipq program successfully
compiles. I add the following rule to the iptables alongwith other iptables 
rule necessary for the MPLS setup:

iptables -A OUTPUT -p icmp -j QUEUE

Now this should queue all originating ping packets and then depending on the
NF mark in my libipq program, action should be taken. But it seems that 
regardless of the NF mark(NF_DROP or NF_ACCEPT), nothing seems to happen. If i 
say NF_DROP in my libipq program, still icmp packets traverse through the 
network from my ingress router. Basically I want to queue specific packets and 
then let my libipq program decide what to do. If accepted then send them to 
the outgoing LSP using spec_nh instruction of MPLS. 

Furthermore, when I run the modprobe commands to check for ipatble_filter and 
ip_queue, I get a fatal message stating "module not found". Could you please 
tell me where I am wrong. I am using the libipq example program provided in 
the manpage.
