We are having trouble with finding ways to redirect the public IP address to the jail IP address. We have looked into the rc.conf and jail.conf files but are now sure how we should edit any of these files to achieve this.
We have previously been unsuccessful in editing pf values...
I run a FreeBSD VPS where it's located a webserver with WHMCS inside. (Apache + Nginx)
I would like to do other kind of ad by running a prank on social media where people will get message like "X has been hacked. Click here to download database" or something similar.
What I need?
I've recently(ish) switched from PF to IPFW because I wanted to use dummynet with fq_codel to fix some rather massive bufferbloat issues I'm seeing on my cable Internet connection with one of the US Cable Monsters. Cable modem is set to pass-through, so the only firewall between me an the...
I have a FreeBSD 11.2 system with Samba installed. If I enable ipfw Samba clients can still connect and browse the filesystem but cannot download most of the files (it looks like the smallest files can be opened). Ipfw is configured in "open" mode:
So I just learned that there's two methods to doing NAT in FreeBSD. The apparently old natd + divert way, which is documented in the handbook, and the new in-kernel ipfw+nat way, that is randomly documented by Google. Is anyone ever going to update the handbook to over ipfw+NAT? The man page...
Hello, thanks to the posts that I found on this forum, I could implement a gateway in FreeBSD that allows me to do flexible policy routing through different interfaces.
I'm going to share.
System: FreeBSD freebsd 12.0-STABLE FreeBSD 12.0-STABLE r346132 NEWKERNEL amd64
I'm using ezjail and IPFW, at least thus far.
So far I have 10.13.13.0/8 subnet. My gateway is .1, my host server is .2, and my first jail is at .3
I noticed that from within my jail at .3 I can knock on the outside if .2.
I added this rule to my host but it makes no difference:
I decided to share my setup for SLAAC on jail vnet.
1. Create bridge and epair interface in /etc/rc.conf
#Configure bridge interface for jails vnet
#epair0 - jail interface
cloned_interfaces="bridge0 epair0" #create bridge and epair
ifconfig_bridge0="ether xx:xx:xx:xx:xx:xx addm re0 SYNCDHCP"...
I'm somewhat of a *BSD novice, having rather used various builds for appliance devices, such as pfSense, opnSense, FreeNAS, etc.
I've recently set up a new FreeNAS box from scratch, and built/building a jail for the express purpose of maintaining OpenVPN client connections, and then...
I installed ShadowSocks VPN with Port: 59080 and Configured IPFW and ByPass this port
Here is my IPFW Configure:
IPF="ipfw -q add"
ipfw -q -f flush
$IPF 10 allow all from any to any via lo0
$IPF 20 deny all from any to 127.0.0.0/8
$IPF 30 deny all...
Hi devs !
I had an idea about how can I reduce my costings but now I need someone who help me translating my idea into PF/IPFW rules.
I would like to buy a cheap dedicated server unprotected against DDoS and a VPS protected anti-DDoS.
I would like to host on dedicated server few games (udp...
Assumptions: Onion router for web browsing with tor DNS, and unlock 80, and 443 port.
What we need: Some time. Some PC or Server or ThinClient, for me is Fuitsu Futro s450 with 2GB of ram and USB LAN adapter, for future is possible to instal into it Network Card at PCI-e or PCI bus.
I've been pulling my hair out over this for days! I have a VM, jails on a loopback interface and using IPFW to NAT the traffic. My findings show that it slows to a crawl. I've also tested with PF and it works like a charm. Network speeds within the jail are fine.
I've tested this on Vultr...
When a T-Mobile "femto-cell" is trying to establish its IPv4, IPSEC tunnel to the T-Mobile provisioning servers, the 4640-byte return packet is silently dropped by the in-kernel NAT, even though it "matches" the outbound packet from less than 100 ms prior.
All other operations of the firewall...
With all the fuzz and issues with security and privacy these days I decided to give it a go with a VPN, mostly for the fun and challenge.
I am partially done with a scenario that sounds very typical these days, although it is not necessary plain vanilla.
The overall idea is...
I don't know if it's Ryzen which is causing this and if it's the Ryzen-bug or if it is something else.
Commands like this are causing kernel-panics:
ipfw table test create type number algo number:array
ipfw table test add 1001
ipfw table test add 1002
ipfw table test add 1003
ipfw table test...
While ipfw supplies me6, I need the list of IPv6 addresses for a specific interface to be used in an ipfw ruleset.
"Screen scraping" ifconfig is one option, but having a firewall at the whim of the human-readable output of even ifconfig is concerning.
Is there a better way with the "stock"...
I have spent days trying to get what I thought should be a simple set of ipfw nat rules set up. With less than zero success. I have read the documentation and scoured the web, and I assume I am just missing something.
Scenario: I have one NIC card with four public IPs. I am running a bunch...
To strength security of the firewall (we all know that ftp is a challenge for firewall security) I want enforce ftp-client establish only a specific port for data.
My box is an ftp client in terms of ftp communication. I don't need ftp server on my box (we live in era of cloud services!), but...
