NFQUEUE and TCP retransmission

+3 votes
247 views

When the following iptables rule is used:
iptables -A INPUT -p tcp --dport 1234 -j NFQUEUE --queue-num 0

If a TCP packet is re-transmitted, will the userspace program receive the re-transmitted packet ? or it just receive one packet, and the re-transmitted one is dropped in kernel space ?
