3 * fix "to <ifname>" bug on FreeBSD 2.2.8
6 ===============================================================================
10 * support redirection like "rdr tun0 0/32 port 80 ..."
12 * use fr_tcpstate() with NAT code for increased NAT usage security or even
13 fr_checkstate() - suspect this is not possible.
15 * add another alias for <thishost> for interfaces <thisif>? as well as
16 all IP#'s associated with the box <myaddrs>?
20 * load balancing across interfaces
22 * record buffering for TCP/UDP
24 * modular application proxying
27 * allow multiple ip addresses in a source route list for ipsend
29 * port IP Filter to Linux
34 * document NAT rule order processing
40 XDDD. I agree. Bandwidth Shapping and QoS (Quality of Service, AKA
41 traffic priorization) should be *TOP* in the TO DO list.
43 * Bandwidth limiting!!!
44 maybe for solaris, otherwise "ALTQ"
47 * Load balancing features added to the NAT code, so that I can have
48 something coming in for 20.20.20.20:80 and it gets shuffled around between
49 internal addresses 10.10.10.1:8000 and 10.10.10.2:8000. or whatever.
50 - done, stage 1 (round robin/split)
51 The one thing that Cisco's PIX has on IPF that I can see is that
52 rewrites the sequence numbers with semi-random ones.
55 I would also love to see a more extensive NAT. It can choose to do
56 rdr and map based on saddr, daddr, sport and dport. (Does the kernel
57 module already have functionality for that and it just needs support in
62 detection of port scans
63 detection of multiple connection attempts
65 * support for multiple log files
66 i.e. all connections to ftp and telnet logged to
69 * multiple levels of log severity with E-mail notification
70 of intrusion alerts or other high priority errors
72 * poison pill facility
73 after detection of a port scan, start sending back
74 large packets of garbage or other packets to
75 otherwise confuse the intruder (ping of death?)
79 * NAT is yet not available, either as a null proxy or address translation
82 * "to <if>" and "to <if>:<ip>" are not supported, but "fastroute" is.
85 * "to <if>:<ip>" is not supported, but "fastroute" is and "to <if>" are.
89 * IPv6 checksum calculation for RST's and ICMP packets is not done (there
90 are routines in the Tru64 kernel to do this but what is the interface?)
92 does bimap allow equal sized subnets?
94 make return-icmp 'intelligent' if no type is given about what type to use?
96 reply-to - enforce packets to pass through interfaces in particular
97 combinations - opposite to "to", set reverse path interface
