Hi,

I'm working in a IPv4/IPv6 address translator with the Click Project at 
http://www.pdos.lcs.mit.edu/click/ . In this moment I'm dealing with the translation 
of FTP/DNS packets, and I have a question. 

If I change the packet content, for example changing PORT 172.25.0.1 for EPRT 
3ffe:1ce1:202:200::1, the packet size is going to change (shrink or grow), are the seq 
and ack numbers going be affected by the translating process so I would have to update 
them? in both cases (yes or no) why? and if they have to be updated, wich would be the 
procedure for doing it?

Thanks for your answers.
