similar to: PF + gif + ipsec + racoon + routing problems results in insecure ipsec vpn

I will shortly be replacing a couple of proprietary VPN boxes with a FreeBSD solution. Section 10.10 of the Handbook has a detailed description of how to do this. However I remember a lot of discussion about a year ago about whether the gif interface was necessary to set up VPNs like this or whether it was just a convenience, for "getting the routing right". A number of people said

Hello, I have given myself quite the headache trying to make this VPN work correctly. I am attempting to use racoon to establish keys and construct an encrypted tunnel between one host(A.A.A.A) with a routable IP address and another that has a private address(10.0.0.2) with a cable modem(B.B.B.B) forwarding all ports to the private address(10.0.0.2). Here is a quick topographic dipiction of the

Hi everyone, First of all, this is my first post in this ML, so I''m not sure that this is the right place for my question (please don''t shoot me down ;)). For the record, I''ve been reading and using LARTC for almost 3 years now, and it''s a great help for anyone who wants to learn linux networking. My problem: I want to setup a tunnel for the following

Hi, Thanks to some pointers from Christian Kratzer, I am now able to join the office VPN from a random WiFi hotspot. With the configuration files changes detailed below, from a public WiFi hotspot I can now use this 3 step procedure to login to the office VPN. 1) While at hotspot, boot up my -STABLE laptop. 2) Insert wireless card. 3) "rsh server" This procedure works for a DHCP

Hi, When a IPSec tunnel is established between two peers, I understand that the "normal" situation is to have in a given moment two SAs, one for each direction of the tunnel. However, in one of my tunnels (peer P1 running GNU/Linux with setkey and racoon; peer P2 is a Cisco router) there is a large number (around 19) of SAs established (this has been observed in P1 with

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

I am trying to get a tunnel from a cisco 1760 with IOS 12.2.15.t13 to a freebsd 4.9 install with racoon. I have package version freebsd-20040408a and internal version 20001216 in my log file. I posted the full racoon and cisco log below my configs. Racoon keeps saying: 2004-07-26 16:24:03: DEBUG: isakmp.c:2295:isakmp_printpacket(): begin. 2004-07-26 16:24:03: DEBUG:

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

Hi, I have FreeBSD box with network interface having y.y.y.y ip address. On same box i configure next ipsec ploicys to process trafic from hardware ipsec enabled device. spdadd 0.0.0.0/0 x.x.x.x/24 any -P out ipsec esp/tunnel/y.y.y.y-z.z.z.z/require; spdadd x.x.x.x/24 0.0.0.0/0 any -P in ipsec esp/tunnel/z.z.z.z-y.y.y.y/require; Is it possible to see decrypted incoming packets, and outgoing

I have tested cisco vpn software,found build the phase ONE successfully,but phase two can't build up. Anyone have advice??

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).

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

Hi folks, I've been working on getting my WiFi network running with IPsec. I'm at the point where all traffic on the wifi subnet is encrypted (i.e. ESP). Then I tried to add AH to the equation. I failed. This picture describes the network setup: http://beta.freebsddiary.org/images/ipsec-wireless.gif Here's what I'm trying and failing with. With these rules, I get no

Hello, My name is Fermín Galán and I''m currently working with IPSec tunnels. Recently, I was setting a IPSec tunnelling sample scenario (maybe the simplest one :), where I observed some strange behaviour that I like to describe in the list, just in the case somebody knows what can be the cause, please. The scenario involves four hosts configured in the following way:

Hi all. The IPSec part of the LARTC howto is great, but I''ve hit a problem in 7.3. IPSEC tunnels. The example given is for manual keying: add 10.0.0.216 10.0.0.11 esp 34501 -m tunnel -E 3des-cbc "123456789012123456789012"; How does one setup "tunnel mode" using racoon?
