...ld Welte just announced that the 2.6 Kernels will not support the ''unclean'' match extension except via Patch-O-Matic. Since I have a polciy of not supporting Netfilter features that are only available in P-O-M, I will be removing the ''logunclean'' and ''dropunclean'' interface options from Shorewall. In 1.4.7, a warning will be issued if these options are specified. In a later release, the warning will be replaced with an error and the code to create ''unclean'' match rules will be removed. -Tom -- Tom Eastep \ Shorewall - ipt...

Hi, I am running Gentoo 1.4, with the 2.4.19 vanilla kernel, and merged shorewall-1.3.9b. I have dropunclean set on eth0 in /etc/shorewall/interfaces. I double checked that I compiled "Unclean match support (EXPERIMENTAL)" into the kernel, but I still get "modprobe: Can''t locate module ipt_unclean" logged when I run ''shorewall status''. Does it really need t...

Another bug with similar symptoms to the last one has been found by Renato Tirol. The bug fixed by the earlier errata update affects the following options: dhcp dropunclean logunclean norfc1918 routefilter multi filterping noping The bug reported by Renato and fixed in the current errata update affects: routestopped The new update is available at: http://www.shorewall.net/pub/shorewall/errata/1.3.1/firewall ftp://ftp.shorewall.net/pub/shorewall/errata/1.3....

...ur 1.4 configuration that will ease the migration when the time comes. a) Shorewall 2.0 doesn''t allow you to specify rate limiting in the ACTION column (e.g., ACCEPT<10/sec:40>) so you will need to move all rate limiting specifications over to the RATE LIMIT column. b) The "dropunclean" and "logunclean" interface options are no longer supported on 2.0 so you should remove them from the OPTIONS column in /etc/shorewall/interfaces. c) The Default value for the ALL INTERFACES column in /etc/shorewall/nat switches from "Yes" to "No".

...ring Sunday to lesson the impact, as they were hammering me with 180k/5sec traffic both ways (inbound and outbound). One of the primary things which helped reduce their DDoS was enabling "norfc1918" on the interfaces (this stopped about 95% of the barrage), but I also enabled routefilter,dropunclean,blacklist and tcpflags. The blacklist feature unfortunately doesn''t do much since the source addresses are faked, but I was able to determine most of the attack was coming from a site in Taiwan. The barrage hasn''t stopped and monitoring it over the last 5 days it''s been...
