Hello, I have configured jail for users with sshd ftpd and auth. I started this jail on IP 127.0.0.10(there is an alias on lo0 interface), there was not any bigger problem to start it. But i have a problem with internet in this jail. I can log in to this jail through ssh or ftpd but i can't connect to the internet. I try to set up some kind of nat but it doesn't work. Can anybody help me

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

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

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

Hey everyone, I'm hoping someone can point me in the right direction. I'm running a 6.1 box with mac_bsdextended compiled. I've created my ugidfw rules, and all seems well in the universe. I've got rules set up so the web process uid 80 and gid 80 can only read uid 1010 and gid 1010 owned files. When the web server tries to do something else, it throws an error such as:

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. 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 ?

CVSup is slow, insecure, and a memory hog. However, until now it's been the only option for keeping an up-to-date ports tree, and (thanks to all of the recent work on vuxml and portaudit) it has become quite obvious that keeping an up-to-date ports tree is very important. To provide a secure, lightweight, and fast alternative to CVSup, I've written portsnap. As the name suggests, this

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:

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

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 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 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, 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
