Subject: Issue related to conntrack while insert new rule with conntrack command in linux
Date: Thu, 25 Apr 2019 13:52:20 +0430	[thread overview]
Message-ID: <8a0187814d06d872011e4026dab073a0@NasimTelecom.com> (raw)

Hello,
I read conntrack document that you wrote about connection tracking. That 
is great.
I have a issue while i am working on it. For example i just want add new 
rule like this:
conntrack -I -p udp -s 192.168.122.242 -d 192.168.122.103 --sport 5070 
--dport 5005 -r 192.168.122.1 -q 192.168.122.103 --reply-port-src 1111 
--reply-port-dst 2222 --timeout 30

But it doen't work.
if i insert these two rule in iptable, the same above rule will insert 
in conntrack table automatically and work correctly.
iptables -t nat -A PREROUTING -i eth0 -p udp -s 192.168.122.242 --dport 
5005 -j DNAT --to 192.168.122.1:1111

iptables -t nat -A POSTROUTING -p udp --dport 1111 -j SNAT --to 
192.168.122.103:2222
Who can i solve this problem?
With Best regards
