ipset not matching in mangle table


Hi All,

I have an ipset group which is configured with a hash:ip,port.

user@svr1:~# ipset list TestSet
Name: TestSet
Type: hash:ip,port
Header: family inet hashsize 1024 maxelem 65536
Size in memory: 16656
References: 7
Members:
10.10.3.186,udp:12345
10.10.3.186,tcp:12345


When I add a record to the POSTROUTING table like this:

iptables -t mangle -I POSTROUTING 1 -m set --match-set TestSet src -j CLASSIFY --set-class 1:99

No packets are ever matched, yet, if I add this record:

iptables -t mangle -I POSTROUTING 1 -p udp -s 10.10.3.186 --sport 12345 -j CLASSIFY --set-class 1:99

It does successfully match the packets.

I can't find any reason why this wouldn't be matching packets as I have sets working fine in other sections.

Has anyone else ever encountered this or am I just overlooking something?

Thanks.
Anubis.

After a lot more searching, I came across the solution from this source - http://thread.gmane.org/gmane.comp.s....general/46123


In the rules above you specified a single direction flag for a two
dimensional set, thus the matching returned "false". If in the first rule
the port is the destination, then it should be:


Which means my rule should have been listed as:

iptables -t mangle -I POSTROUTING 1 -m set --match-set TestSet src,src -j CLASSIFY --set-class 1:99


Once correcting the missing ",src" the rule's working perfectly.

Hope this is able to help some others in the future.

Anubis.
