hello,
after configuration ipsec in ip4 I can not ping between client and server whereas I had success ping before configuration!
I also generate different key for AH and ESP as i have shown below.
what is my problem and what should i do to have ping and test the configuration?

Hello! I have some trouble trying to configure a VPN with two gateways. One of them uses IPSec with a single key, 256bits length, specified in /etc/ipsec.secrets. As FreeSwan manual page says, if i put esp=3des-md5-96, will be used a "64bit IV key (internally generated), a 192bit 3des ekey and a... (3 Replies)
Hi,
does anyone have an experience how many IPSec tunnels Solaris 10 is able manage. A rough estimation would be great.
I know it's hardly dependent on the hardware used, so if anyone says on a 490 with 2 CPUs and 4GB RAM a maximum of 1000 IPSec tunnels is possible, that would be great.

Hi,
I am facing problem while setting up ISAKMP between two hosts.
I can see only the Initiator messages but no responder messages in tcpdump. Does anyone know the cause of this behaviour?
FYI, here is the extracted information from tcpdump :

Hello,
I'm trying to setup a gateway VPN between two routers across an unsecured network between two local networks. The routers are both linux and I'm using the ipsec tools, racoon and setkey. So far hosts from either local net can successfully ping hosts on the other local net without issue.

Hi,
I am trying to set a policy between 2 machines for all the ports except for 22 i.e. for tcp - basically I want to bypass ssh. But my policy doesn't seem to work. Here are the entries

Hello Admin :)
Can I have an ask for something with my configuration ?
I have finished some kind of the tutorial to build ipsec site to site, and the "step" has finished completely.
I have a simulation with a local design topology with two PC's (FreeBSD ... (0 Replies)
Hi Guys,
Please could you tell me if it is possible to have a single rule/filter to allow a certain port range instead of a separate rule for each port?
I'm sure it must be possible but I am unable to find the syntax.
Thanks

Hi all,
I have installed Openswan and configured IPSec and works perfect, but for some unknown reasons it stop working. I see that the tunnels are up and established. The route to the destination are added. Everything by the book seems to be ok. But somehow when i start to ping the other side (... (4 Replies)

KAME_IPSEC(4) BSD Kernel Interfaces Manual KAME_IPSEC(4)NAME
ipsec -- IP security protocol
SYNOPSIS
#include <sys/types.h>
#include <netinet/in.h>
#include <netinet6/ipsec.h>
options KAME_IPSEC
options IPSEC_ESP
options IPSEC_NAT_T
options IPSEC_DEBUG
DESCRIPTION
ipsec is the first implemtation of IPSEC in NetBSD. It is being replaced by fast_ipsec(4).
The following kernel options are available:
options IPSEC
Includes support for the IPsec protocol. IPSEC will enable secret key management part, policy management part, AH and IPComp. Kernel binary
will not be subject to export control in most of countries, even if compiled with IPSEC. For example, it should be okay to export it from
the United States of America. INET6 and IPSEC are orthogonal so you can get IPv4-only kernel with IPsec support, IPv4/v6 dual support kernel
without IPsec, and so forth. This option requires INET at this moment, but it should not.
options IPSEC_DEBUG
Enables debugging code in IPsec stack. This option assumes IPSEC.
options IPSEC_ESP
Includes support for IPsec ESP protocol. IPSEC_ESP will enable source code that is subject to export control in some countries (including
the United States), and compiled kernel binary will be subject to certain restriction. This option assumes IPSEC.
options IPSEC_NAT_T
Includes support for IPsec Network Address Translator Traversal (NAT-T), as described in RFCs 3947 and 3948. This feature might be patent-
encumbered in some countries. This option assumes IPSEC and IPSEC_ESP.

Daniel L. McDonald, Craig Metz, and Bao G. Phan, PF_KEY Key Management API, Version 2, RFC, 2367.
HISTORY
The implementation described herein appeared in WIDE/KAME IPv6/IPsec stack.
BUGS
The IPsec support is subject to change as the IPsec protocols develop.
There is no single standard for policy engine API, so the policy engine API described herein is just for KAME implementation.
AH and tunnel mode encapsulation may not work as you might expect. If you configure inbound ``require'' policy against AH tunnel or any
IPsec encapsulating policy with AH (like ``esp/tunnel/A-B/use ah/transport/A-B/require''), tunneled packets will be rejected. This is
because we enforce policy check on inner packet on reception, and AH authenticates encapsulating (outer) packet, not the encapsulated (inner)
packet (so for the receiving kernel there's no sign of authenticity). The issue will be solved when we revamp our policy engine to keep all
the packet decapsulation history.
Under certain condition, truncated result may be raised from the kernel against SADB_DUMP and SADB_SPDDUMP operation on PF_KEY socket. This
occurs if there are too many database entries in the kernel and socket buffer for the PF_KEY socket is insufficient. If you manipulate many
IPsec key/policy database entries, increase the size of socket buffer or use sysctl(8) interface.
