Hello, I am using the following iptables POSTROUTING rule to NAT some RFC 1918 addresses: iptables -t nat -A POSTROUTING -s 192.168.19.23 ! 192.168.0.0/255.255.0.0 -p tcp --dport 80 -j SNAT --to-source 10.32.4.2 (I am using SNAT instead of MASQUERADE for performance reasons). I have several addresses on the 192.168.0.0/16 subnet that I am SNAT''ing similarly. Problem is, ''tc

hello my name is Ludovico Ausiello, i'm a ph.d at the university of Bologna and I've developped an open source alternative to proprietary philips superAudioCD encoder (that actually cost some thousands dollars!) that has better performance (it's seems strange.. but..) I'm interested to use the flac encoder to compress the 1-bit stream that is the output of my encoder (I start

I wanted to test this on another kernel again but haven't had a chance since your last post. I will say that I was going to test a few months ago but with the last kernel I tested (I think it was from 2012), I had

I''m wondering if the following is possible under recent versions of shorewall: 1. We have several class-C networks from both UUNet and Internap, both of which are actually routed over a single inbound ethernet line from UUNet at our colocation facility: 204.176.148.0/23 and 216.52.83.0/24. This gives us a total of 3 class-C subnets. All packets for these three subnets would land on

Last week, I started seeing very strange behavior in one of the networks that I manage. The office LAN uses a Linux firewall which masquerades their workstations over their DSL connection. There are probably ~75 workstations in the office LAN. Their mail server is in a collocated facility nearby. That server has an RFC1918 address; its router does SNAT to forward packets to the system. Both

Here's my proposed patch to change RST handling so that ESTABLISHED connections are subject to strict RST checking, but connections in other states are only subject to the "within the window" check. Part 2 of the patch is simply a patch to netstat so that it displays the statistic. As expected, it's very straightforward, the only real question is what to call the statistic...

A number of you are flailing around trying to get the subject combination to work. You should all be aware that there are parts of this that don''t currently work and that won''t work well until there are enhancements made to Shorewall (and probably to Netfilter). I. There is no clean way currently to support Road Warriors from a Masquerading Netfilter firewall/gateway. As

I have a dsl modem and two static IP addresses: 66.17.65.22 and 66.17.65.161.

I want to set up a shorewall 2.08 router for my home (Fedora Core 2 / kernel 2.6.8-1.521). I want share an internet connection with some pc''son a local

Hi ! I have setup a complete shorewall now with DMZ, and Private zones and masq, rules, port-forwarding etc. worx like expected. BUT I have a wish to use a couple of more public IP''s and relate those to inernal servers on the DMZ zone and i am now so confused about it. I have searched this archive for SNAT port allow Setup: 3 public adresses on the WAN nic. lets call them 80.80.80.80 -
