[Bug 172771] Cannot use NOTRACK netfilter target with iptables: unknown error

[LGB [Gábor Lénárt]]

Public bug reported:

I badly need 'NOTRACK' because of very heavy traffic (DNS recursive
lookup requests) so I've decided to disable connection tracking for
these packets. However the domumented (iptables man page) NOTRACK target
does not work (on Gutsy, and dapper it seems to be OK). What can I do? I
can't reboot/update/etc running machines at the moment.

I've tried this command:

iptables -t raw -A PREROUTING -p udp -m udp --dport 53 -j NOTRACK

Result of that command on 64 bit Edgy (kernel is 2.6.17-10-server):

iptables: Unknown error 18446744073709551615

On 32 bit Edgy  (kernel is 2.6.17-12-server):

iptables: Unknown error 4294967295

On 32 bit Feisty:

iptables: No chain/target/match by that name
