Dear all, I''m setting up a new gateway for a small network (under 30 users)Gw will host the following services:shorewalldnsproxy i''m considering installing snort.can i do so on the same exact box ? is there any security risk of doing so ? box would have 4 ISPs and two internal interfaces. Any recommendation about the optimal setup of snort and shorewall (or if you suggest

Hi, I have 2 Debian testing boxes running a very similar setup (both running the latest aptosid kernel); on one of them, since the iptables/libxtables10 packages have been upgraded from 1.4.19.1-1 to 1.4.20-2, shorewall-init can''t start shorewall anymore and for this reason ifupdown also fails triggering firewall up. Shorewall can be successfully started later on, and ifupdown starts

I''m using the following rule on 3 different systems running shorewall-4.5.18 on Gentoo: ACCEPT all all icmp - - - 10/sec:20 shorewall starts fine on 2 of the systems but on the 3rd it fails to start with the following error: iptables-restore: line 119 failed ERROR: iptables-restore Failed. Input is in /var/lib/shorewall/.iptables-restore-input /usr/share/shorewall/lib.common: line 113:

When using shorewall with a road warrior openvpn setup, how can I get the tun interface to masq through a lan interface? Example Setup: Machine A (tun0 10.0.0.1) -----------VPN---------(tun0 10.0.0.2)---------Machine B(10.10.10.1) When I ping Machine B from Machine B, Machine B is receiving the echo request, but it doesn''t know the route back to the 10.0.0.0/24, and there

Hi I''m running on a debian box shorewall-4.5.17. My main gateway is a router running on openwrt and I want to use the shorewall-lite packet provided by openwrt. The openwrt''s provided shorewall-lite packet is 4.5.7. So my questions would be: 1: Do I need to make some modifications before installing shorewall-core-4.5.7/shorewall-4.5.7 on my debian box? 2: if I have both

Hi All, I have a custom TC configuration where I''m building the tc hierarchy manually with the tcstart script. I also need to add custom iptables rules in the mangle table to classify the packets. Currently I''m using started to insert the iptables commands, but that''s way too late in the process. I tried putting them into the initdone file, but it''s trying to

I use since a lot of time a "classical" two-interfaces setup, with the net interface connected to an ADSL modem in half-bridge mode, which receives a public IP from the ISP and gives it to the Linux net interface; the lan interface has the 192.168.30.0/24 class. Now I need to change this setup, because my new ISP (that will switch soon to a FTTS VDSL2 connection) sent me a VDSL2

Hi folks, I''m having an issue with rsync between my firewall and an internal box. It seems to be a shorewall issue (or correctly speaking, an issue with my shorewall config) because if I disable shorewall my rsync works fine. And I just can''t find it documented anywhere what I need to do. I have rules like this : root@userver:/etc/shorewall# grep -i Rsync rules

Hi, My main gateway is a router running on OpenWrt Barrier Breaker r37816/ Kernel Version3.10.4. I installed shorewall-lite from openwrt''s repo using opkg but while trying to start shorewall-lite I get the folowing errors: The first error i got was "scp: /var/lib/shorewall-lite: No such file or directory" simply resolved by making the folder "shorewall-lite"

hello, while starting shorewall4.5.20 on debian7 I get the following from touch touch: cannot touch `/var/lock/subsys/shorewall'': No such file or directory The needed file can not be created because the directory subsys is not present! If I creat the folder manuallly touch does not complain when shorewall start! Thus it would be nice if durring start shorewall could check if the

Hi, I use shorewall-4.5.4 + lsm-0.143 and it does not seem to work as expected... When all providers are up, everything seems fine. When one goes down, lsm says "link <provider> down event"... and it seems ok but we then experience some problems such as a few unreachable sites, DNS problems... If I remove the downed provider from all confs and restart, everything works again.

Hi all. I can''t seem to get the h323 connection tracking configured correctly for Shorewall. I am using the Debian Shorewall 4.5.16.1 package. I am running a Debian 3.9 kernel like so: # uname -a Linux gw 3.9-1-amd64 #1 SMP Debian 3.9.8-1 x86_64 GNU/Linux My version of iptables is: # iptables -V iptables v1.4.20 If I add the following rule in the /etc/shorewall/tcrules file to

I stumbled upon a problem while upgrading Ubuntu 13.04, Shorewall version from 4.4.26.1 to 4.5.16.1. Everything was working fine before, after upgrading the script wouldn''t start. First some config files. tcdevices: #INTERFACE IN-BANDWIDTH OUT-BANDWIDTH OPTIONS REDIRECTED eth1 - 6300kbit hfsc,classify ifb0 - 6300kbit hfsc

Hi all, I need an help to implement this kind of rules on shorewall: iptables --insert INPUT -p udp --dport 53 -m u32 --u32 "0x28&0xFFDFDFDF=0x055a5a47 && 0x2c&0xDFDFFFDF=0x53540343 && 0x30&0xDFDFFFFF=0x4f4d0000" -j DROP This kind of rules need to block a DNS Amplification Attack. I found this file

I give up and need help! I won''t add to the confusion by showing all the combinations I have tried unsuccessfully... and yes, I''ve read FAQ2 and FAQ2a many times! When googling the subject of this post there are many answers that boil down to using the same three iptables rules, two of which use nat. I won''t repeat them here. I don''t want to risk mixing

Hi, I have servers where shorewall6 won''t reject nor log: # cat /etc/shorewall6/zones fw firewall net ipv6 # cat /etc/shorewall6/interfaces net eth1 tcpflags (I also tried without "tcpflags", but no changes) # cat /etc/shorewall6/policy $FW all ACCEPT all all REJECT info # cat /etc/shorewall6/rules SECTION NEW (for testing, I removed all the rules) I am testing from

Hi, I want to configure QoS in my shorewall conf but I have a doubt. Now I am using tcrules with prerouting and with the file providers, like this. 2:P 192.168.0.11 0.0.0.0/0 tcp 25 So, with this way I route my smtp traffic with my provider number 2. Well, now I want to configure QoS with tcclasses and tcdevices, but if I do that I need to use the MARK in the tcclasses So, how

the establishment of an openvpn link sometimes fails. I tracked it down to network traffic with wrong Sourceport in the answer packet (should be 1300 not 1024): 2 1.119309000 aaa.185.165 bbb.162.192 UDP 58 Source port: 1300 Destination port: 1300 3 1.119446000 bbb.162.192 aaa.185.165 UDP 66 Source port: 1024 Destination port: 1300 and a collateral entry in the connection tracking table

I''m trying to use my VPS server (single interface of course) as somewhat of a VPN gateway to my other location (which is not accessible directly from some places) where the openvpn server is running, and am kind of lost as to what to try next. I tried a redirect rule, but apparently shorewall didn''t like that (it just failed to start). I tried adding the rules via
