1BUGS: 2----- 3* fix "to <ifname>" bug on FreeBSD 2.2.8 4fastroute works 5 6=============================================================================== 7GENERAL: 8-------- 9 10* support redirection like "rdr tun0 0/32 port 80 ..." 11 12* use fr_tcpstate() with NAT code for increased NAT usage security or even 13 fr_checkstate() - suspect this is not possible. 14 15* add another alias for <thishost> for interfaces <thisif>? as well as 16 all IP#'s associated with the box <myaddrs>? 17 18time permitting: 19 20* load balancing across interfaces 21 22* record buffering for TCP/UDP 23 24* document bimap 25 26* document NAT rule order processing 27 28* add more docs 29in progress 30 313.4: 32XDDD. I agree. Bandwidth Shapping and QoS (Quality of Service, AKA 33traffic priorization) should be *TOP* in the TO DO list. 34 35* Bandwidth limiting!!! 36maybe for solaris, otherwise "ALTQ" 37* More examples 38* More documentation 39* Load balancing features added to the NAT code, so that I can have 40something coming in for 20.20.20.20:80 and it gets shuffled around between 41internal addresses 10.10.10.1:8000 and 10.10.10.2:8000. or whatever. 42- done, stage 1 (round robin/split) 43The one thing that Cisco's PIX has on IPF that I can see is that 44rewrites the sequence numbers with semi-random ones. 45- done 46 47I would also love to see a more extensive NAT. It can choose to do 48rdr and map based on saddr, daddr, sport and dport. (Does the kernel 49module already have functionality for that and it just needs support in 50the userland ipnat?) 51-done 52 53 * intrusion detection 54 detection of port scans 55 detection of multiple connection attempts 56 57 * support for multiple log files 58 i.e. all connections to ftp and telnet logged to 59 a seperate log file 60 61 * multiple levels of log severity with E-mail notification 62 of intrusion alerts or other high priority errors 63 64 * poison pill facility 65 after detection of a port scan, start sending back 66 large packets of garbage or other packets to 67 otherwise confuse the intruder (ping of death?) 68 69IPv6: 70----- 71* NAT is yet not available, either as a null proxy or address translation 72 73BSD: 74* "to <if>" and "to <if>:<ip>" are not supported, but "fastroute" is. 75 76Solaris: 77* "to <if>:<ip>" is not supported, but "fastroute" is and "to <if>" are. 78 79Tru64: 80------ 81* IPv6 checksum calculation for RST's and ICMP packets is not done (there 82 are routines in the Tru64 kernel to do this but what is the interface?) 83 84does bimap allow equal sized subnets? 85 86make return-icmp 'intelligent' if no type is given about what type to use? 87 88reply-to - enforce packets to pass through interfaces in particular 89combinations - opposite to "to", set reverse path interface 90 91
