Question

JUNIPER SSL VPN ?How does it work ?

Asked by: alimohammed72

HI

I AM NEW TO JUNIPER SSL VPN.WHEN I LOGIN INTO our SSL VPN https://secure.myvpn.com I am asked to enter username/passcode(RSA)/password.After I put this info I see all published realms in SSL VPN like (CITRIX,etc),at this point I can access my corporate e-mail(Lotus Notes) from my home.At Home I use the same laptop as at Work except I get my home ISP ip address like 99.29.29.x.The destination network for me is 10.32.0.0/22 and 172.17.0.0/16

My question is how am I communicating with the corporate mail server(10.32.1.93) when I actually launch lotus notes client from my laptop (not through tHE cITRIX pORTAL) That has ip like 99.29.29.x ?How is this communication happening between public and private ip ?Also I am trying to understand that How am  I  actually connect to 172.17.1.1 using pc ANYWHWERE directly from my Laptop ?My previous VPN experience with Cisco concentrators tell me that I need to get an aip from the destination network before accessing the resources from that network

 

Thanks

The answer is "it depends" on how the box was configured.

Juniper SSL boxes use a variety of different ways to secure access to resources within your office lan.

If we take your lotus notes for now, the most common way of allowing the access from your laptop notes app to the lotus server is using Secure Application Manager.  This comes in 2 flavours, the WSAM (for windows machines, uses activex) or JSAM (java version, runs on all platforms).

These SAMs will then intercept the traffic/requests for the lotus server and send it down the SSL tunnel or alternatively re write your hosts file to do the interception.

Same goes for all other apps, ike outlook, pcanywhere etc, the traffic is intercepted and sent down the tunnel.

Other options include network connect, which is a full IPSEC client over SSL and gives you a network connect IP from the SSL VPN box and basically grants full network access.

Does this answer your questions?

 

by: alimohammed72Posted on 2009-08-12 at 15:20:32ID: 25083673

1.Is there any way to check whether I am using WSAM or JSAM ?

2.Do I see the  difference in the HOSTS file during "connected" and "not connected"

3.Network Connect means I need to install client on my laptop ?

4.Does this Interception procedure translates any ip address in to the destination ip subnet so that they can talk to each other ?

Thanks Again

1.  In your system tray, you should have a SAM program, if itds java, then its JSAM and your hosts file will be  edited.  If its not java, then its WSAM and it will simply intercept the traffic

2.  Only in JSAM.

3.  Yes, NC has a client, but its a small browser plugin.  It will have n icon in your system tray if its running.

4.  No, it just takes the traffic for your mail server (for example) and send its down the SSL tunnel rather than send it to your default GW

How about PING and TRACERROUTE ?Do they work with SAM ?I could not ping the servers.

 

by: deimarkPosted on 2009-08-13 at 08:08:23ID: 25089195

Nope, unless you use network connect and get a new IP (with routing info for the internal servers) these will not work.

Secure Application Manager, well, manages secure connections for applications.
