Hello, I was wondering if there was a simple way for a kernel module to create a NAT rule "on the fly". For example, a TCP connection request (i.e. SYN packet) is received by its destination host, and that host (for whatever reason) wants a different host to service this connection... I've got a kernel module listening for these "connection redirects" on the gateway into the complex, and would like it to be able to insert a rule into the NAT table then send the packet up to ip_rcv() such that this specific connection will end up being NAT'd to the other host. Is there a simple way to accomplish this? I was hoping there would be an insert_rule() function, but it looks like the tables are modified by a doing a get_table(), modify the local copy, then replace_table(). Any help you could pass onto me would be greatly appreciated! Thank you, Duane Cloud
