3 * fix "to <ifname>" bug on FreeBSD 2.2.8
6 ===============================================================================
10 * use fr_tcpstate() with NAT code for increased NAT usage security or even
11 fr_checkstate() - suspect this is not possible.
15 * load balancing across interfaces
17 * record buffering for TCP/UDP
19 * modular application proxying
22 * allow multiple ip addresses in a source route list for ipsend
24 * complete Linux port to implement all the IP Filter features
25 return-rst done, to/dup-to/fastroute remain - ip_forward() problems :-(
28 * add a flag to automate src spoofing
31 * ipfsync() should change IP#'s in current mappings as well as what's
37 * document NAT rule order processing
43 XDDD. I agree. Bandwidth Shapping and QoS (Quality of Service, AKA
44 traffic priorization) should be *TOP* in the TO DO list.
47 * Bandwidth limiting!!!
50 * And did I mention bandwidth limiting???
51 * Load balancing features added to the NAT code, so that I can have
52 something coming in for 20.20.20.20:80 and it gets shuffled around between
53 internal addresses 10.10.10.1:8000 and 10.10.10.2:8000. or whatever.
54 - done, stage 1 (round robin/split)
55 The one thing that Cisco's PIX has on IPF that I can see is that
56 rewrites the sequence numbers with semi-random ones.
58 I would also love to see a more extensive NAT. It can choose to do
59 rdr and map based on saddr, daddr, sport and dport. (Does the kernel
60 module already have functionality for that and it just needs support in
64 detection of port scans
65 detection of multiple connection attempts
67 * support for multiple log files
68 i.e. all connections to ftp and telnet logged to
71 * multiple levels of log severity with E-mail notification
72 of intrusion alerts or other high priority errors
74 * poison pill facility
75 after detection of a port scan, start sending back
76 large packets of garbage or other packets to
77 otherwise confuse the intruder (ping of death?)
79 * I ran into your solaris streams stuff and noticed you are
80 playing with mblk's in an unsafe way. You seem to be modifying the
81 underlying datab without checking db_ref. If db_ref is greater than one,
82 you'll need to copy the mblk,
85 * fix up where manual pages go for Solaris2
90 * NAT is yet not available, either as a null proxy or address translation
93 * "to <if>" and "to <if>:<ip>" are not supported, but "fastroute" is.
97 * "to <if>:<ip>" is not supported, but "fastroute" is and "to <if>" are.
