Add a tcp option at the NAT device
Hello,
I am using a linux machine as NAT device which function is to map internal addresses 192.168.x.y to an external address.
What i want to do is to add a TCP option to SYN packets sent hosts.
I think that adding the TCP option has to be done in tcp_output.c file but I don't known in which function.
Anybody has an idea about such manipulation?
Thanks in advance.
