I''m getting insane here. I''m running shorewall 1.3.11 with iptables 1.2.5 and freeswan 1.97 on a 2.4.18-8 kernel aka MNF. The setup is a followed: Lan (192.168.1.x) - FW (eth1 192.168.1.254 - eth0 64.x.y.71) - router 64.x.y.65 (which is default GW on eth0) -internet - 161.a.b.c (FW-1) So a windows client with checkpoint tries to connect to a vpn-1 server on the internet. The

I am attempting to create an ipsec tunnel between two CentOS 5.1 systems, network-to-network with two different 192.168.xxx.0/24 LAN segments. I have gone through the documentation on the centos web site, and have the machines to the point where the /var/log/messages show ``IPsec-SA established'' on both machines after runnig ``ifup ipsec0'' (same ipsec0 on each machine). IP

This one is a bit complex so if no help is forthcoming, I understand. I have 2 shorewall firewalls (1.3.13) up and running. (both machines running Gentoo Linux 1.4_rc2) I have freeswan (1.98) running on each of them. I have squid setup as a caching/filtering server on each of them. Each of them was originally setup using the Two-interface Quick Start Guide. Then the Squid guide and then the IPSEC

I am new to Shorewall and FreeSwan, please excuse my ignorance I was wondering if someone could help me. I had help getting my FreeSwan running with the following iptables commands: iptables -I FORWARD -s 0/0 -d 192.168.1.0/24 -i ipsec0 -o eth1 -j ACCEPT iptables -I FORWARD -s 192.168.1.0/24 -d 0/0 -i eth1 -o ipsec0 -j ACCEPT If I manually run this FreeSwan works, however I am not sure

IF you are not stuck to IPSec, you might want to take a look at OpenVPN (www.openvpn.org). I found OpenVPN easier to install than FreeSWAN (an IPSEC VPN) and have setup an OpenVPN solution between my German office and our mainoffice in a matter of hours.

I am have a shorewall firewall and freeswan ipsec running on a redhat 8.0 Linux gateway machine. I have one working tunnel defined, all works well. I am not clear how to define mutiple concurrent tunnels. I can not add further interface entries as all the tunnels come in on ipsec0, do I still have mutiple zone definitions? some of the tunnels will be dynamic roadwarriors and as such would need a

It seems to me that ipsecnat tunnel type is not complete. Latest drafts of ipsec nat-traversal use udp port 4500 for nat-traversal communications. (It''s called port floating). That is needed to get rid of ugly ipsec passthru devices. Now ipsecnat opens port udp/500 from any source port. And I think ipsecnat won''t work at all with gw zone defined? I''m not sure about

Hi list, I am trying to create a VPN between two different locations. On the first location we have a cisco pix 525 Natting the internal 192.168.100.x network, while on the second location we have a Centos3 box Natting via iptables the internal 192.168.10.x netowrk. My goal is to connect this 2 over the internet via IPsec. I created the IPsec Net2Net via the network configuration graphic

Hi, Could not conceive an working set-up for an IPSEC VPN made with racoon/setkey on which I have one address on my side acting as an SNAT router for all traffic from my network to a network segment on the far side. my network --- my gateway ---------------------- remote network 10.0.0.0/24 - 10.0.0.1 (10.253.0.2) -- tunnel - 192.168.0.0/22 All traffic starts on my side, so if I can

Hi all! I have got a vpn connection set up using FreeSwan and shorewall. Everything works fine but I want to add another subnet to the whole. This means that 1 box will get two net-to-net connections. I want to limit the services on one subnet however. Cuurently I have defined a vpn zone for the current connection and allow all vpn<->loc traffic. How would I go about in tightening the

Hi. I am trying to force some traffic that goes to address 203.7.93.94 through a VPN tunnel. I use freeswan 1.98b and Shorewall 1.4.6c in one machine. The 203.7.93.94 is in the DMZ on the other end. (Both ends use the same shorewall and freeswan). I have successfully set up a tunnel between the two network (using a point to point topology, not hub). I added a static routing that redirect

Hello, I seem to have the Freeswan IPSEC tunnel working between my two sites, but I am still having a problem that looks to be because of something I have configured wrong in my shorewall setup.. I have a LEAF Oxygen < 1.9 heavily modifed firewall setup.. Using FreeSwan 1.91, and Kernel 2.4.8. Modified to use IPTables and standard Debian network/interfaces. I am also using Shorewall

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I''m trying to setup a central IPSEC-Gateway with several ipsec tunnels.

Hi, I have been using IPsec to communicate between a laptop that tracks -stable and a Linksys BEFVP41 router. I only use it infrequently, but it's been working great. My setup is as described in http://grapeape.alerce.com/linksys-ipsec/article.html (which I am planning to submit to the handbook when it's done). I'm no longer able to make an ipsec connection, and I can't put my

Hi, I am trying to setup an IPSEC transport between a Windows 2000 box and a FreeBSD server for a customer... Both systems are on live public IP's and packets are not filtered by any intermediate systems or firewalls/routers in between. I have the following setup: Windows 2000 box: 1.1.1.2 FreeBSD Server: 2.2.2.3 (The actual IP's have been changed to above to protect the innocent..)

I have no idea whatsoever as to why racoon/IKE does not work here. I've tried various how-to documents but found nothing that works for me. Gateway (10.0.0.1) running 4.9-stable. Laptop (10.0.0.10) running 5.2.1-release. Both running racoon-20040408a On the gateway 10.0.0.1 # cat /etc/ipsec.conf add 10.0.0.1 10.0.0.10 esp 691 -E rijndael-cbc "1234567890123456" -A hmac-sha1

Hi all, I am trying to establish a vpn tunnel between one CentOS5 IPSec server and a roadwarrior client, CentOS5 too. Roadwarrior use ipsec-tools version 0.6.5-8 (that comes with CentOS5) and server uses version 0.7 (downloaded from ipsec-tools website). My server configuration is: path include "/etc/racoon"; path certificate "/etc/racoon/certs"; path pre_shared_key

Hi all. The IPSec part of the LARTC howto is great, but I''ve hit a problem in 7.3. IPSEC tunnels.

hello i am trying to set up ipsec in my network, for now just between two hosts, using to use AH & ESP in tunnel mode to get all of packet encrypted. keys are negotiated with racoon. mayby using tunnel mode in this case can seems strange, but i know what i am doing. after setting up everything i have done few tests with ping & tcpdump. but the results are very suprising. bellow is what i
