Hi, Using shorewall for the first time (a woody .deb of version 1.2.12). After reading the docs, I still have a couple of questions regarding some parameters from the interfaces file. 1) Is rfc1918 not just a specific implementation of routefilter ? The sample file in two-interface.tgz uses them both, but they seem to at least overlap. Since my internal network will be 192.168.1.0/24, will

Hello, I believe there may be a bug in shorewall version 2.0.8. I''ve been using shorewall for years without problems (last installed version was 1.4.6b-1). I''ve posted previously with the subject line "After upgrade people can no longer connect" dated on Sunday, September 19, 2004 which contains all the information for the upgrade. Today I uninstalled shorewall

Hi, I need a help... I''m a beginner with shorewall. I have two shorewall firewalls, each with a link. FW (a) - w/ openVPN eth0 = 192.168.150.5/24 eth1 = 192.168.200.5/24 eth2 = public IP eth3 = 192.168.120.5/24 tun240 = 10.240.255.1 /etc/shorewall/zones all zones declared as ipv4 /etc/shorewall/interfaces #ZONE INTERFACE BROADCAST OPTIONS tlm eth0

http://shorewall.net/pub/shorewall/Snapshots ftp://shorewall.net/pub/shorewall/Snapshots Problems Corrected since version 1.4.6: 1) Corrected problem in 1.4.6 where the MANGLE_ENABLED variable was being tested before it was set. 2) Corrected handling of MAC addresses in the SOURCE column of the tcrules file. Previously, these addresses resulted in an invalid iptables command.

Hi, i connect to the internet over my eth4 interface using pppoe. The internet always comes on ppp0. I am trying to setup an L2TP/IPSEC VPN and i am reading http://www.shorewall.net/IPSEC-2.6.html#RW-L2TP I notice in the example the interfaces file is given as: #ZONE INTERFACE BROADCAST OPTIONS net eth0 detect routefilter loc eth1

Hello Tom, I''ve been using Shorewall for years without problems. My previous version of shorewall was 1.4.6b-1. Everything worked just fine. Today I upgraded using rpm to 2.0.8-1. After update no one can connect to any interface from net. Server can connect to outside world fine and those described in routestopped have no problem connecting. Any help correcting this problem would be

I am trying shorewall as my previous post With alisias on eth1 loc and 4 pptp client vpns. The odd thing is when I enter one of the vpns in interfaces such as vpn1 it works. But if I enter the vpn in the hosts file shorewall blocks the vpns. shorewall/hosts #ZONE HOST(S) OPTIONS loc eth1:192.168.25.0/24 loctw eth1:192.168.50.0/24 locsa eth1:192.168.75.0/24 vpntw

In the panic of replacing our firewall(s) earlier in the week, we ended up moving our original shorewall 1.4 config onto a machine with 2.0.10 already installed, overwriting all the 2.0.10 config files. Most things seem to work fine, except for our masq entries. I''ve examined the default 2.0.10 files compared with our 1.4 files, and can''t spot the problem. What am I missing?

I''m converting my network from a "one interface per segment" to a "single connection with vlans", well, some hardware I have requires using different vlan IDs. suffice it to say I need bridges to connect a few different vlans that should all be one but can''t be because of firmware constraints. so my first step is to get shorewall to know about bridges.

Hello all, Yesterday I noticed that my system was "leaking" traffic towards the 10/8 network, I have shorewall installed on multiple machines ranging from single interface devices to ones with 10+ interfaces. I tested all the boxes and they are showing the same behavior. All systems are CentOS 3.4, 2.4.21-27.0.2.ELsmp. Shorewall version: 2.2.1 For the host mentioned is a single

...compatibly. Previously, the effective value was determined by the setting of net.ipv4.config.dev.proxy_arp logically ANDed with the setting of net.ipv4.config.all.proxy_arp. Beginning with kernel 2.6.31, the value is the arithmetic MAX of those two values. Additionally, a ''loose'' routefiltering facility is now enabled by setting the effective value of proxy_arp to 2. Given that Shorewall sets net.ipv4.config.all.proxy_arp to 1 if there are any interfaces specifying ''routefilter'', specifying ''routefilter'' on any interface has the effect of setting the o...

Hi, I have a Linux firewall based on shorewall with 2 NIC and ADSL (ppp0). My ppp0 ip is fixed. The internal NIC, eth1, is bridged with tap0, tap1 and tap2 to form br0. br0 subnet is 192.168.2.0/24. The firewall is configured to masq internal traffic and block whatever needs to be blocked. It is also configured to tunnel openvpn v1.6. I have a roaming laptop running XP. I can create a tunnel

I have a dsl modem and two static IP addresses: 66.17.65.22 and 66.17.65.161. I am using the standard configuration from the Shorewall Setup Guide for multiple IP addresses and modifications suggested by the Aliased Interfaces Guide. 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

Hello, Thanks for the great Shorewall which has replaced my hard to maintain home-made scripts. First, what works. Our local network is 10.48.X.X with multiple vlan, each on a dedicated interface. We use Shorewall 4.4.11 from Debian Squeeze. We have a 2 ISP: - isp1 : an optical fiber provider with 10 Mbps. - isp2 : a DSL provider with 15Mbits/1Mbits. We use isp2 as the default outgoing

Hi ! Recently i switched my internet provider, to get more speed but another braindead setup regarding public ip addresses.
