Hi all: I have strange probelm with rc.conf. I set up ipfw (compiled into kernel) on freebsd-5.4 and it doesn't seem to load ipfw rulesets (it uses default ruleset 65335 locking out everything). I have to do "sh /etc/ipfw.rules" in order to load the rulesets, once I did that, I can access the box from remote locations here is my rc.conf: host# more /etc/rc.conf

Hi, After the option IPFILTER_DEFAULT_BLOCK is specified at kernel conf on FreeBSD 4.8 stable (cvsup'd with tag RELENG_4_8), the machine cannot be ping'd by others on the same network. In addition, the machine cannot ping itself. ping localhost (or 127.0.0.1) -> no route to host ping itself with its own ip address -> no route to host The freebsd box, with an external pppoe

Hello all, I want to learn about requirements if I want to protect gigabit network with ipfilter as transparent firewall. Which type of hardware is required to install FreeBSD + ipf (as transparancy ) . We use 3 gigabit ethernet to protection which type of gigabit ethernet carts are powerfull. Also, what about the NMBCLUSTERS , IPSTATE_SIZE and IPSTATE_MAX in ip_state.h. I want to collect all

Hi! I'm trying to increase security on my FreeBSD 4.8 firewall/DSL router/VPN router. My problem is with firewalling the VPN part. I'm using a tunnel to a RedHat 7.1 box running FreeS/WAN. This tunnel allows traffic from my internal net (172.17.0.0/24) to that box only: spdadd 172.17.0.0/24 $REDHAT/32 any -P out ipsec esp/tunnel/$MYADDR-$REDHAT/unique; spdadd $REDHAT/32 172.17.0.0/24

I've found out from two different kernel configs that after properly compling kernel with IPFILTER support it causes the system not to boot. Its hard to say, what exactly it does, cause its not a local system. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to

Hello, Some time ago I wrote PR conf/48170, which discussed the following problem: Syslog messages of facility LOG_AUTHPRIV and priority LOG_NOTICE (or higher) are sent by default to the world-readable log file /var/log/messages. That seems unacceptable since the facility LOG_AUTHPRIV is for hiding sensitive log messages inside a protected file, e.g., /var/log/auth.log. For example, login(1)

Hi. On my FreeBSD 4.8 configured IPFW2+IPF+IPNAT and I use them all: - IPFW - traffic accounting, shaping, balancing and filtering; - IPFilter - policy routing; - IPNAT - masquerading. I want to know, how IP-packets flow through all of this components? What's the path? incoming: IPFW Layer2 -> IPFW&Dummynet -> IPNAT -> IPFilter ? outgoing: IPFW Layer2 ->

Hello I am trying to set up a backup server running Solaris 8 with rsync 2.5.5 and ipfilter the latest version. The problem i have is i have about 16 different interfaces that are secured via ipfilter , and i tried running rsync via rsh but ipfilter would not set up a keepstate with rsh which meant i had to open up and that is not acceptable. So what i tried then was via ssh and that worked fine

Has anyone gotten a transparent firewall working? I''m using snv_125 on an IBM x346 (snv_130 goes into endless boot loops on this hardware). I can create a working bridge with dladm, but can''t stop packets, even with "block in quick all". That stops packets on my management interface bge0, but not on the bridge. :( tim at ghost:~# ifconfig -a lo0:

Hi all. I didn't find any thread discussing it, sorry if I am re-posting the same subject. Is there a way to check the ipfilter/ipfw out-flow with bridge? Is it implemented? I've heard its not done due a performance issue (it's writen in ipf-howto), but performance is not the main goal for me in this single situation. I would like to have the stateful firewall and the bridge _fully_

Hi, sorry for cross-mailing. Reply-to: set to freebsd-net. I have seen some discussion on freebsd-security etc. about some parts of the subject. I have seen older messages in archives. Regularly the same questions seem to come up. I have not found an all-including description of the answer to s.th. like: "Can anybody tell me the order packets get processed in kernel related to IPSec,

This looks like a very cool feature addition to RELENG_7! Are there any performance penalties that you know of with this built in ? ---Mike At 09:13 PM 7/23/2008, Julian Elischer wrote: >julian 2008-07-24 01:13:22 UTC > > FreeBSD src repository > > Modified files: (Branch: RELENG_7) > contrib/pf/pfctl parse.y > lib/libc/sys

I'm setting up a server where I plan to use Jails to improve security I also have installed and am configuring ipfilter. Here are my questions: Because I'm using Jails, I will have to have multiple ip aliases on the network interface. I will use ipfilter to specify what can go to each of the addresses. (e.g., allow only incoming to port 80 on the jail running apache). Another

Hi, I have a 4.7-RELEASE system. I used the following cvsupfile to update my system: *default host=cvsup2.FreeBSD.org *default base=/usr *default prefix=/usr *default release=cvs *default tag=RELENG_4_8 *default delete use-rel-suffix src-all *default tag=. I then proceeded to do: cd /usr/src make buildworld I got a bunch of errors which occurred when building kdump:

I want to run a non-global zone as a virtual router and run ipnat inside the non-global zone, however, when I try to enable routing it can''t find route:default or network/ipfilter. I''m using exclusive IP inside the zones and using OpenSolaris 2008.11 build 110. I''ve tried sparse root and whole root zones without success. I''ve read blogs and posts and

We're supposed to provide redundant firewall service. I'm wondering if anyone has ever tried to do this and if it's realistic. Basically 2 firewall machines hooked up so if one fails the other will transparently step in. I've googled it to death without much luck. The security issue here lies in that the 2 firewalls can't talk to each other. So if I'm keeping state on

Hi all, Link protection is a new feature we are planning to introduce to Solaris and we would like to solicit your feedback on it. Please see attached document for details.

Hello Routing Gurus ;-) I''d like to know if it''s possible to make a routing decision for pakets originating from a specific port of the local machine without using ipfilter/iptables to mark the pakets. I read about the tc filter stuff but that seems only to be able to sort the pakets to a different queue on the same interface and not choose a different interface for example. Is
