Hi I have shorewall/iptables running on my server (pub) but access to localhost is blocked then I attemp to use ping localhost, telnet localhost 25, echo Hello | sendmail -v root@localhost. All these commands were run after using shorewall reset and creating the attached file. All these commands work with shorewall clear. My problem is I can''t email the root messages from (pub) to

I have a multi-isp configuration: CGCO 1 256 main $CGCOIF detect track,balance br-lan,tun0 IGS 2 512 main $IGSIF detect track,fallback br-lan,tun0 where I force SMTP out one of the connections: 512:P br-lan - tcp 25 But the effect of that of course is that if IGS goes down, SMTP will leak out of the CGCO connection. How can I prevent that? Cheers, b.

Hi everyone! I''m having time out problems when using a DNAT rule. Rule: DNAT:info cmtc loc:192.168.0.158 tcp 8011 Log: Mar 17 17:50:17 gw kernel: [1583997.524924] Shorewall:cmtc_dnat:DNAT:IN=eth3 OUT= SRC=10.1.0.2 DST=10.0.0.2 LEN=60 TOS=0x10 PREC=0x00 TTL=62 ID=4279 DF PROTO=TCP SPT=32791 DPT=8011 WINDOW=5840 RES=0x00 SYN URGP=0 Telnet: root@emudar:~# telnet

Hi, I realise that one can simply start fail2ban and then it will insert its own ruleset before shorewall''s ruleset. Are there subscribers to this list having alternative (and probably better) ways to use both fail2ban and shorewall?

Hi I am having a problem with a DNAT rule where the packets being REJECT''d: DNAT:info net priv:192.168.6.15 udp 5060 With the following appearing in the log: Mar 6 11:59:30 ipcop kernel: Shorewall:net2fw:REJECT:IN=eth3 OUT= MAC=00:09:6b:6e:48:e8:00:1d:20:fa:46:90:08:00 SRC=71.216.136.25 DST=67.138.129.66 LEN=629 TOS=0x10 PREC=0xA0 TTL=50 ID=28000

I would like to dnat certain protocols (HTTP, HTTPS, SSH) to the contents of an ipset (lan:+serviceshost or similar) where the ipset is ensured to contain only one host, but can be changed dynamically when services are in maintenance mode and go to the "services are down" message on another server. Will this work, or am I barking up a fish here?

I am attempting to use the Knock.pm from http://www.shorewall.net/ManualChains.html I am not having much luck making the DNAT- knock work for some reason. Anyone else using this on 4.4.4 that can verify if this still works as documented? Thanks ------------------------------------------------------------------------------ Return on Information: Google Enterprise Search pays you back Get the

Hi, I have a rule: DNAT net dmz:a.b.c.d tcp 25 - k.l.m.n The problem: I want to DNAT port 25, 143, 110 k.l.m.n is alternate public ip (using vrrp, just like alias) Can I abridge the above line using macro, instead of writing 3 separate lines? I can do: MailPorts/DNAT net dmz:a.b.c.d But this refer to the physical public ip I have more elaborate requirement to forward around 20

Hello list, I am in the process of switching from IPCOP to Shorewall s the firewall for our small office. I very much like the fact that Shorewall runs on top of the same OS (openSuSE 11.4) that I run on the server and my desktop. Our setup is fairly straightforward. We have 8 static ip addresses from our ISP, which provides a cable modem and a Cisco 800 series router. The ip addresses are

Hi there. I''m reading and reading through the doc''s and previous posts, but cannot seem to find what I''m looking for. I want to create a rule that prevents DoS and maybe even DDoS attacks against a specific port. The current rule looks like this (the PORT''s and IP''s are dummies of course): #ACTION SOURCE DEST

Hi list, I have a shorewall installed on 2 interfaces which also has multiple static public IP. Let''s say I have 1.2.3.4 and 1.2.3.5. I have assigned nat with: 1.2.3.4 eth0 11.22.33.4 no no But then I have a situation where I need 11.22.33.44 to connect to a host in the net zone and appears also to be 1.2.3.5 not only 1.2.3.4. How to do it? TIA Willy

I have been trying to get DNAT to work and I actually have succeeded too, however, not how I thought it would work when reading through the documentation. 1. No matter what I do I cannot get DNAT to work unless I have an entry in eiter the nat or the proxyarp file. Is that really how it''s supposed to be? I can''t find anything about it in the documentation. 2. Also, in the

Hello, I''m migrating my laptop setup to a shiny new ThnikPad W520 and in the process am getting rid of VirtualBox (marked by kernel maintainers as "unsupportable crap" or some such) and shifting to virt-manager/kvm. As with the old setup I am running shorewall-init exactly as the great online documentation lays it out. BUT: with VBox it was enough to add > net

Hi everyone! First of all, sorry about my bad English and the e-mails extension. I need some help to implement a VPN connection using shorewall and openswan as IPSec Tunnel. My network map: CLIENT VPN APPLIANCE --> +++INTERNET+++ --> FIREWALL --> OPENSWAN SERVER (DMZ) I have two VPN connections with two different subnets to the other end. The two of then are correctly established.
