say hello little sweet juniper 5gt for testing purposes; got her on 6.2.0r8 – not recommend by juniper but by now she runs stable 🙂

Ipsec tunnel / openswan <-> juniper ssg5

finally got it working: building a bidirectional ipsec tunnel between a juniper ssg5 and openswan@debian, both sites got static ip adresses

openswan config:


conn juniper_ssg5_01
type=tunnel
authby=secret
auth=esp
pfs=yes
rekey=yes
auto=start
keylife=8h
keyingtries=0
keyexchange=ike
ike=aes256-sha1-modp2048
esp=aes256-sha1
# Linux openswan
leftid=1.1.1.1
left=1.1.1.1 # expernal ip
leftsubnet=10.1.10.0/24

# SSG 5
rightid=2.2.2.2
right=2.2.2.2 # untrust interface

screenOS or junOS ?

thinking about the differences between ssg and srx juniper firewall devices. my main focus is on stability and usual features like VPN stuff. srx devices might deliver some more and better features (on the other hand i.e. lack of ipv6 support (but announced)); for me it seems like the ssg devices are more stable and i know that they can do what i need to do.  ssg5 i.e. has been started last year, the end of life of ssg series is far away (hope so). the administration stuff (console, web) has changed completely in junOS – another reason to stay on ssg devices.  anyway: i`m pretty sure in a few years junOS will be the choice …

right now i`m using a SSG550M / planning to replace several linux VPN gateways with SSG5 boxes

snort / openvas / cain

installed snort-mysql  / acidbase on debian testing and did a base configuration in 5 minutes; after installing the necassary sql files, i only had to uncomment one line in the snort configfile, set the subnet to scan, define the nic – done. always really impressive what you can do/see with this piece of free software after 10 minutes. also installed a openvas server – it seems like there is no windows client out there. nice so see that the cain & abel toolkit is still under development.   i need these systems for a demo / lecture on wednesday …

edit: the openvas-client using macports under os x works pretty good.
