This is used to modify the IPv4 TTL header field. The TTL field determines
|
|
how many hops (routers) a packet can traverse until it's time to live is
|
|
exceeded.
|
|
.PP
|
|
Setting or incrementing the TTL field can potentially be very dangerous,
|
|
so it should be avoided at any cost. This target is only valid in
|
|
.B mangle
|
|
table.
|
|
.PP
|
|
.B Don't ever set or increment the value on packets that leave your local network!
|
|
.TP
|
|
\fB\-\-ttl\-set\fP \fIvalue\fP

|
|
.TP
|
|
\fB\-\-ttl\-dec\fP \fIvalue\fP
|
|

|
|
.TP
|
|
\fB\-\-ttl\-inc\fP \fIvalue\fP
|
|
