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 -...

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...

Hello! This problem has been persisted on two different MBs (diffrent CPUs, different memory), half dozen of different NICs, 4.7-RELEASE and 4.8-RELEASE. Common router/NAT (ipnat, kld loaded) behaves very strangely after about 10-20 minutes of work. New processes doesn't create anymore, process trying to fork looks in top having -20 PRI and "temp" STATE. I was unable to find out what that state means. New TCP connections from internal networks fails to create...

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.

...ernal addresses to first get translated and then routed through the tunnel. But instead when I connect with my internal addresses they get translated, but then try and use the conventional gateway on the machine instead of picking up the ipsec policy. If that makes sense... I am using FreeBSD, ipf, ipnat and racoon. Any help appreciated Simon

Howdy all, I posted this message to the netfilter mailing-list and didn''t get much response. I apologize if anyone here is getting this for a second time. Anyway, I recently migrated my firewall from a FreeBSD box running ipfilter, ipnat and dummynet to a Gentoo Linux box running netfilter and tc. I have to admit that I''m having problems visualizing tc in my head. So, I was wondering if I could get an assist. Basically, when I run my NNTP client, it uses as much bandwidth as it can get its grubby paws on. I have a 3M...

Hi, I plan to connect to remote Asterisk that will terminate calls to ISDN primary channel. I'd certainly like to secure this type of service, so would kindly ask for any advice on how to secure this authentication as much as reasonably possible. Since there is long IP route I guess VPN will take too much additional bandwidth... Regards, Robert.

...her side being taken over, so this does not help me here. Any hints how to resolve this are welcome. I don't think this is a general IPFilter problem, hence I'm asking on this mailing list rather than that for IPFilter. Thank you, Lupe Christoph PS: There was talk about the sequence IPFW/IPNat/IPFilter get invoked. It would be interesting to put the IPSec code in this picture. Are IPSec packets going through *any* of them? With/out GIF? -- | lupe@lupe-christoph.de | http://www.lupe-christoph.de/ | | "Violence is the resort of the violent" Lu Tze...

hi i have a problem with my icmp, i have a router that performs nat. i cannot ping to internet hosts from more than one stations situated behind NAT at once. if i want to ping from another station i have to stop the ping that was initiated from the first host, and after a few seconds i can ping from another station.i've checked firewll and i have no ipfw rules that could stop icmp traffic.

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

I have a rule set, but for testing purposes here, until I get this working, I do a pass in/out quick on all interfaces. ip.forward is on, and NAT is working. So as a firewall and gateway, I'm good, just no joy with the VPN yet. I will leave off most of the extra i...

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'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
