>Description:
The ipnat(5) man page is inconsistent with actual behaviour for redirection (rdr) rules.
From ipnat(5):
redir ::= "rdr" ifname ipmask dport "->" ip [ "," ip ] [ ports ] options
and
options ::= [ tcpudp ] [ rr ]
But if you try to omit the [ ports ]:
root@ericnernie# ipnat -n -f -
rdr tun0 0/32 port 7010-7019 -> 192.168.0.3
1: No netmask supported in destination host for redirect
1: syntax error in "rdr"
rdr tun0 0/32 port 7010-7019 -> 192.168.0.3 tcp
2: missing fields - 2nd port (tcp)
2: syntax error in "rdr"
rdr tun0 0/32 port 7010-7019 -> 192.168.0.3 port 7010 tcp
>How-To-Repeat:
N/A
>Fix:
Amend the manpage so that
redir ::= "rdr" ifname ipmask dport "->" ip [ "," ip ] [ ports ] options
reads as
redir ::= "rdr" ifname ipmask dport "->" ip [ "," ip ] ports options
