tcp checksum incorrect
hello !!
I have a question about sk_buff in kernel 2.6.x .
I registered a netfilter hook module which can change ip address of sk_buff at POST_ROUTING hook.
I changed the source ip address,then the packet were sent out from server. In my client host,i used the ethereal to get these packets,then i found checksum incorrect. Why ??(i already chagned ip_summed = CHECKSUM_HW in my hook.)
Please help me !! thx
