1*bc4097aaSchristosBUGS:
2*bc4097aaSchristos-----
3*bc4097aaSchristos* fix "to <ifname>" bug on FreeBSD 2.2.8
4*bc4097aaSchristosfastroute works
5*bc4097aaSchristos
6*bc4097aaSchristos===============================================================================
7*bc4097aaSchristosGENERAL:
8*bc4097aaSchristos--------
9*bc4097aaSchristos
10*bc4097aaSchristos* support redirection like "rdr tun0 0/32 port 80 ..."
11*bc4097aaSchristos
12*bc4097aaSchristos* use fr_tcpstate() with NAT code for increased NAT usage security or even
13*bc4097aaSchristos  fr_checkstate() - suspect this is not possible.
14*bc4097aaSchristos
15*bc4097aaSchristos* add another alias for <thishost> for interfaces <thisif>? as well as
16*bc4097aaSchristos  all IP#'s associated with the box <myaddrs>?
17*bc4097aaSchristos
18*bc4097aaSchristostime permitting:
19*bc4097aaSchristos
20*bc4097aaSchristos* load balancing across interfaces
21*bc4097aaSchristos
22*bc4097aaSchristos* record buffering for TCP/UDP
23*bc4097aaSchristos
24*bc4097aaSchristos* document bimap
25*bc4097aaSchristos
26*bc4097aaSchristos* document NAT rule order processing
27*bc4097aaSchristos
28*bc4097aaSchristos* add more docs
29*bc4097aaSchristosin progress
30*bc4097aaSchristos
31*bc4097aaSchristos3.4:
32*bc4097aaSchristosXDDD. I agree. Bandwidth Shapping and QoS (Quality of Service, AKA
33*bc4097aaSchristostraffic priorization) should be *TOP* in the TO DO list.
34*bc4097aaSchristos
35*bc4097aaSchristos* Bandwidth limiting!!!
36*bc4097aaSchristosmaybe for solaris, otherwise "ALTQ"
37*bc4097aaSchristos* More examples
38*bc4097aaSchristos* More documentation
39*bc4097aaSchristos* Load balancing features added to the NAT code, so that I can have
40*bc4097aaSchristossomething coming in for 20.20.20.20:80 and it gets shuffled around between
41*bc4097aaSchristosinternal addresses 10.10.10.1:8000 and 10.10.10.2:8000. or whatever.
42*bc4097aaSchristos- done, stage 1 (round robin/split)
43*bc4097aaSchristosThe one thing that Cisco's PIX has on IPF that I can see is that
44*bc4097aaSchristosrewrites the sequence numbers with semi-random ones.
45*bc4097aaSchristos- done
46*bc4097aaSchristos
47*bc4097aaSchristosI would also love to see a more extensive NAT.  It can choose to do
48*bc4097aaSchristosrdr and map based on saddr, daddr, sport and dport.  (Does the kernel
49*bc4097aaSchristosmodule already have functionality for that and it just needs support in
50*bc4097aaSchristosthe userland ipnat?)
51*bc4097aaSchristos-done
52*bc4097aaSchristos
53*bc4097aaSchristos        * intrusion detection
54*bc4097aaSchristos                detection of port scans
55*bc4097aaSchristos                detection of multiple connection attempts
56*bc4097aaSchristos
57*bc4097aaSchristos        * support for multiple log files
58*bc4097aaSchristos                i.e. all connections to ftp and telnet logged to
59*bc4097aaSchristos                        a seperate log file
60*bc4097aaSchristos
61*bc4097aaSchristos        * multiple levels of log severity with E-mail notification
62*bc4097aaSchristos                of intrusion alerts or other high priority errors
63*bc4097aaSchristos
64*bc4097aaSchristos        * poison pill facility
65*bc4097aaSchristos                after detection of a port scan, start sending back
66*bc4097aaSchristos                large packets of garbage or other packets to
67*bc4097aaSchristos                otherwise confuse the intruder (ping of death?)
68*bc4097aaSchristos
69*bc4097aaSchristosIPv6:
70*bc4097aaSchristos-----
71*bc4097aaSchristos* NAT is yet not available, either as a null proxy or address translation
72*bc4097aaSchristos
73*bc4097aaSchristosBSD:
74*bc4097aaSchristos* "to <if>" and "to <if>:<ip>" are not supported, but "fastroute" is.
75*bc4097aaSchristos
76*bc4097aaSchristosSolaris:
77*bc4097aaSchristos* "to <if>:<ip>" is not supported, but "fastroute" is and "to <if>" are.
78*bc4097aaSchristos
79*bc4097aaSchristosTru64:
80*bc4097aaSchristos------
81*bc4097aaSchristos* IPv6 checksum calculation for RST's and ICMP packets is not done (there
82*bc4097aaSchristos  are routines in the Tru64 kernel to do this but what is the interface?)
83*bc4097aaSchristos
84*bc4097aaSchristosdoes bimap allow equal sized subnets?
85*bc4097aaSchristos
86*bc4097aaSchristosmake return-icmp 'intelligent' if no type is given about what type to use?
87*bc4097aaSchristos
88*bc4097aaSchristosreply-to - enforce packets to pass through interfaces in particular
89*bc4097aaSchristoscombinations - opposite to "to", set reverse path interface
