Hi all, I just found an interesting issue and wish to have your confirmation: My network setup is like the following: PC1 and the Internet<---->PC2<---->PC3 PC2 is doing nat for PC3 and is transparant to PC3. I start transmitting a large file using ftp from PC1 to PC3 via PC2. During the transmission, I disable all the nat rules on PC2 (iptables -F & iptables -F -t nat), but PC2 goes on doing nat until finishing transmitting the whole file. Only after that the connectivity between PC1 and PC3 breaks. Could anyone tell me the reason for this phenomenon? Cheers, Jee
