Tunnelling Puppet over SSH
I work at a large financial institution (AXA) and we have a large number of DMZs for our partner and internet-facing servers. The only access to the various DMZs is via SSH and no DMZ-initiated connections are allowed back to the internal network. I''d consider putting a Puppet server in the DMZ but no communication is allowed between DMZs either. Has anyone tried tunnelling Puppet

Correct way to use quagga and shorewall
Hi, I''ve setup quagga on a shorewall firewall server. The only purpose for this is to use BGP to connect to a "peering platform" supplied by our data centre supplier. There are some very large ISP''s (and other various providers including google) on this peering platform and connecting to it will speed up access to/from our services and hosted servers. The physical

Shorewall + IPSec: help debugging why gw1<->gw2 SA works, but loc<->gw2 traffic doesn't trigger SA
Dear list, I''m running Shorewall on a dedicated Fedora 7 box. Shorewall is working well as an office DSL router (dynamic IP) with loc and dmz zones. I am now trying to configure IPSec to connect a VPS, "casp", with a static IP to both the firewall and to the loc network behind it. The host to host SA works fine. However, pings from "loc" to "casp" can be

IProute2 and netfilter interactions
I am trying to build a firewall and from my reading of the list archives and other places, I''m worried about unintended interactions between iptables and iproute2. Here is my situation I have an internal network on eth0 and two separate dmzs on eth1 and eth2 respectively (a wireless network and a kiosk). On the outbound side, I have a cablemodem provider and a dsl provider. What I

IPSEC VPN to VPN firewalling problem
Dear Shorewall Users :-) I''ve been playing with shorewall for some time now - I found it really interesting and easy tool to organise all the rules and so on (beforethat I''ve been using simple iptables rules in shell script ;-) Generally it''s quite easy to be used, but anyway found one problem which I cannot handle myself - or in other words - cannot find appropriate

Basically, I have a rackmount server with six network cards. eth0 is the internal network, eth1 is a kiosk network, eth2 is a DMZ/wireless network. On the outbound side, eth3 is a DSL connection and eth4 is a cablemodem connection. What I am trying to do is route all internal

Connecting CentOS to IPSEC VPN (Checkpoint FW1)
Hi, Does anyone have experience using IPSEC on CentOS in order to connect to vendor IPSEC-based VPN products (specifically Checkpoint FW1) ? Is the included IPSEC implementation sufficient, or do people have to rely on OpenSWAN or FreeSWAN ? I'd be testing tomorrow and I'm interested with experiences others have had and things to look out for. Thanks in advance, -- dag wieers, dag

(no subject)
We had a running ipsec shorewall system to all of our remote offices. We added a dmz to the firewall and implemented proxy arp for that dmz. We have checked everything two or three times and cannot figure out why the vpns will no longer come up. We are using shorewall version 2.2.3 from the debian stable sarge distribution. We noticed the errata that for 2.0.0 there was a problem with proxy

RE: Q: Routing the Same IP simultaneously on differentcomputers ?
Hi, First, never compare a linux box with a cheap and dumb broadband router.

Shorewall as a "commercial" firewall

I have two ISP''s (with separate routing tables), two DMZ''s, at least one VPN to a remote office, and a local trusted network. The configuration will look like: +----------------+ | | net0 ----------+ eth1

Zebra, Routing ...
Before I start, I don''t want to do ECMP or simple bonding ... I have multiple Internet connections available to multiple boxes on one of my networks. Box A connects to ISPs 1, 2 and 3 Box B connects to ISPs 1 and 4 Boxes A and B are both connected to each other and the rest of the network. 1) I would like to set up some dynamic routing in such a way that any given outgoing packet from
