title: Maximum value of TCP sequence number
body: <p>I'm trying to capture packets and reorganize packets for obtaining original HTTP request.</p>
  
  <p>I'm capturing packets by IPQUEUE(by iptables rule), and I figured out that packets are not captured in order.</p>
  
  <p>I already know that in TCP protocol, packets have to be re-sequenced, so I'm trying to re-sequence packets by sequence number.</p>
  
  <p>According to Wikipedia, the sequence number of TCP is 32 bits number. Then, what happens if sequence number reaches to MAX 32bits number?</p>
  
  <p>Because sequence number of SYN packet is random number, I think this limitation can be reached very fast.</p>
  
  <p>If anybody has a commend on it, or has some links helpful, please leave me a answer.</p>
