Hello,
I'm running a 7.0-RELEASE machine. I've backported the 7-STABLE for
ng_nat, because I'm really interested in the static NAT features from
libalias.
ng_nat(4) says:
| NGM_NAT_REDIRECT_ADDR (redirectaddr)
| Redirect traffic for public IP address to a machine on the local
| network. This function is known as static NAT. The following
| struct ng_nat_redirect_addr must be supplied as argument.
|
| struct ng_nat_redirect_addr {
| struct in_addr local_addr;
| struct in_addr alias_addr;
| char description[NG_NAT_DESC_LENGTH];
| };
|
| Unique ID for this redirection is returned as response to this
| message.
I'm a little confused on exactly how to pass a struct as a message to a
netgraph node via ngctl. What am I missing here?
Thanks,
