ipfw2 logging
Dear list! I have a little problem, trying to enable logging of deny rule. I have enabled it via kernel: options IPFIREWALL options IPFIREWALL_VERBOSE options IPFIREWALL_VERBOSE_LIMIT=3 It is ipfw2. After that, my inten- tion was to use syslogd and !ipfw *.* /var/log/ipfw.log and newsyslog with /var/log/ipfw.log 600 3 100 * J In rc.conf I have firewall_enable="YES"

IPFIREWALL_DEFAULT_TO_ACCEPT becomes default to deny
Hey Guys, today I upgraded to 4.8-RELEASE-p15. As usual I set IPFIREWALL to default accept in my kernel config file. Config & make weren't complaining so, installed the kernel, reboot and there it was: >IP packet filtering initialized, divert disabled, rule-based forwarding enabled, default to deny, logging disabled Another rebuild didn't work out so... I reviewed

traffic normalizer for ipfw?
Hi there, Is there some way to configure ipfw to do traffic normalizing ("scrubbing", as in ipf for OpenBSD)? Is there any tool to do it for FreeBSD firewalling? I've heard that ipf was ported on current, anything else? TIA, /Dorin. __________________________________ Do you Yahoo!? Yahoo!

Listening outside ipfw / program interface to ipfw
Hi, Two quick questions that I can't seem to find answers for using google. 1) is is possible to listen outside an ipfw firewall - that is have ethereal record the packets before ipfw starts dropping them? If so how? 2) Is there an api to ipfw that will let me manipulate rules, query stats etc? I need something faster than running the command line binary? Thanks John

Policy routing with IPFW
Hi There, I've been having an issue trying to figure out a way to policy route outbound packets from a multihomed machine through the proper interface using IPFW to no avail. I've tried several different incantations of IPFW fwd/forward statements, and none of them seem to do the trick. Basically, I have a host that has multiple Internet connections. This host is running FreeBSD 4.9

Reducing the need to compile a custom kernel
Hi, during some big discussions in the last monts on various lists, one of the problems was that some people would like to use freebsd-update but can't as they are using a custom kernel. With all the kernel modules we provide, the need for a custom kernel should be small, but on the other hand, we do not provide a small kernel-skeleton where you can load just the modules you need.

ipfw2 in 5.2.1
hi - this is my first post to this list so go easy on me ! I am trying to find info on using ipfw2 with freebsd 5.2.1 as I have read that it supports MAC address based firewalling. Situation is, I have a small externally managed VPN network, about 12 different subnets all terminating in my office location, and all managed by a tier 1 telco. Problem is, their CPE routers do not have any firewalling

SYN Attacks - how i cant stop it
Hi, I got this error when i tried to type for some of those. "sysctl: unknown oid...." any idea.. my server seems to be very lagged, where else the network connection seems fine, i think BSD itself as my other redhat box is fine. What else can i do to get optimum protection. Thanks. ----- Original Message ----- From: "Per Engelbrecht" <per@xterm.dk> To:

5.1-R-p2 crashes on SMP with AMI RAID and Intel 1000/Pro
Dear Sirs. It seems to me a never ending story. We run a box with a TYAN Thunder 2500 Dual SMP mainboard, 2GB ECC Tyan certified memory, AMI Enterprise 1600 RAID adapter and additional Intel 1000/Pro server type (64 bit) GBit LAN NIC. With FreeBSD 4.8 this was stable, but to achive this state was really hard! It is a story similar to that what happend when we changed towards FreeBSD

strange problem with ipfw and rc.conf
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

Packet flow through IPFW+IPF+IPNAT ?
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 ->

IPFW Problems?
Hi, I have a system with a 4.11 Kernel. Unless I'm doing something very wrong, there seems to be something odd with ipfw. Take the following rules: ipfw add 00280 allow tcp from any to any 22 out via bge0 setup keep- state ipfw add 00299 deny log all from any to any out via bge0 ipfw add 0430 allow log tcp from any to me 22 in via bge0 setup limit src-addr 2 ipfw add 00499 deny log

panic with today's stable
Did cvsup on a machine that does just mail processing (well, a lot of spam scanning) and it crashed not too much later. This kernel does not include MFC src/sys/kern/sys_process.c revisions 1.111 and 1.112: Use kmem_alloc_nofault() rather than kmem_alloc_pageable() in procfs_rwmem(). Use vm_page_hold() in place of vm_page_wire() since the page can be freed. Don't hold extra

Best way to filter "Nachi pings"?
We're being ping-flooded by the Nachi worm, which probes subnets for systems to attack by sending 92-byte ping packets. Unfortunately, IPFW doesn't seem to have the ability to filter packets by length. Assuming that I stick with IPFW, what's the best way to stem the tide? --Brett Glass
