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

I have a FreeBSD box acting as a firewall and NAT gateway I would like to set it up to transparently pass IPSec packets -- I have an IPSec VPN client running on another machine, connecting to a remote network. Is there a way to do this? I can't find any hints in the man pages.

hi all i'm trying to get ipfilter set up on my new 5.1-RELEASE box. ipfilter seems to be working fine. i just have a couple of issues that are probably not very serious... one thing is that during network startup at boot, i get the message IPFilter: already initialized repeated 4 times. i think i have everything configured properly my kernel config looks like options IPFILTER options

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 ->

In http://docs.freebsd.org/cgi/mid.cgi?200402260743.IAA18903 it seems RELENG_4 is vulnerable. Is there any work around to a system that has to have ports open ?

Hello. I am a relatively new FreeBSD user. I have samba, ssh and vnc server running on it. I am also trying to set up the IPFILTER on it. I used the handbook to familiarize myself with the software and the sample script provided in the chapter discussing ipf, I decided to use as a starting point. After reading the ipf chapter I assumed that if "block in log first quick on xl0 all" is

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 afraid about having find a freebsd 5X security issue. We have recently upgraded one gateway from 4.10 to 5.3... Following network used: [ISP]--xl1--[FW01]-----xl0--em0--[SR01] | |--fxp0--em0--[SR02] On fw01, we have one jail. So fw01 is configured as a bridge on xl1,xl0,fxp0. Services works (before and after upgrade). On 4.10, we used

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

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 All, I setup a new Centos 5.5 bod and it will be running a site for me. Apache is running and daily I get e-mailed a log from the box. The log today said: --------------------- httpd Begin ------------------------ Requests with error response codes 404 Not Found http://www.cablecarmuseum.org/Car42.jpg: 1 Time(s) ---------------------- httpd End ------------------------- But that

I've been using ipfw for a while to create a router with NAT and packet filtering, but have never combined it with stateful filtering, instead using things like "established" to accept incoming TCP packets which are part of a conversation initiated from the "inside". I'd like to move to using keep-state/check-state to get tighter filtering and also to allow outgoing

Hi, When deploying a BSD with IPF in at the network perimeter and using rules like these: pass in .. proto tcp ... keep state(strict) it's possible to refuse tcp packets which arrive out of order. This would increase the difficulty doing blind attack resets and blind data injection attack, cause then you'd have to "guess" the exact expected number. Checpoint has a similar

Hi, first i must tell you, that my english is not the best, i hav learned my english from manpages and documentation. Please excuse this. I have setted up a Box w/FreeBSD 4.7-RELEASE for connecting to the w3 through an DSL/ATM-Connection. Now i know the stateful handling of firewall-rules under linux with iptables.In the second i have understand that FreeBSD comes with the netfilter-extensions.

I've had ipf working on a few 5.3 servers for quite awhile. Not too long ago some developers had to do some coding work and were coming from dynamic IP's. I (reluctantly) opened up SSH to the world. Immediately I started seeing the attacks where bots of some sort would try to break in with a variety of different users. So, I (thought) I closed it up again and told the developers to use a

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:

Greetings, Apologies if this is not the appropriate list, but my questions are about best practices in maintaining production servers (so I believe I can justify a post in -stable, short of a -release list :) I maintain a modest installation of 6 FreeBSD servers. They're CVSUP'd to RELENG_4_8 (I make buildworld on each individually) and I portupgrade ports as necessary. In an attempt to
