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)

ipsecesp
ipsecesp(7P) Protocols ipsecesp(7P)NAME
ipsecesp, ESP - IPsec Encapsulating Security Payload
SYNOPSIS
drv/ipsecesp
DESCRIPTION
The ipsecesp module provides confidentiality, integrity, authentication, and partial sequence integrity (replay protection) to IP data-
grams. The encapsulating security payload (ESP) encapsulates its data, enabling it to protect data that follows in the datagram. For TCP
packets, ESP encapsulates the TCP header and its data only. If the packet is an IP in IP datagram, ESP protects the inner IP datagram.
Per-socket policy allows "self-encapsulation" so ESP can encapsulate IP options when necessary. See ipsec(7P).
Unlike the authentication header (AH), ESP allows multiple varieties of datagram protection. (Using a single datagram protection form can
expose vulnerabilities.) For example, only ESP can be used to provide confidentiality. But protecting confidentiality alone exposes vulner-
abilities in both replay attacks and cut-and-paste attacks. Similarly, if ESP protects only integrity and does not fully protect against
eavesdropping, it may provide weaker protection than AH. See ipsecah(7P).
ESP Device
ESP is implemented as a module that is auto-pushed on top of IP. Use the /dev/ipsecesp entry to tune ESP with ndd(1M).
Algorithms
ESPuses encryption and authentication algorithms. Authentication algorithms include HMAC-MD5 and HMAC-SHA-1. Encryption algorithms include
DES, Triple-DES, Blowfish and AES. Each authentication and encryption algorithm contain key size and key format properties. You can obtain
a list of authentication and encryption algorithms and their properties by using the ipsecalgs(1M) command. You can also use the functions
described in the getipsecalgbyname(3NSL) man page to retrieve the properties of algorithms. Because of export laws in the United States,
not all encryption algorithms are available outside of the United States.
Security Considerations
ESP without authentication exposes vulnerabilities to cut-and-paste cryptographic attacks as well as eavesdropping attacks. Like AH, ESP is
vulnerable to eavesdropping when used without confidentiality.
