Question

Port forwarding on Juniper SSG 20

Asked by: Funktopus

Hello,

Need assistance.

I've searched here and other sites - and found semi relevant info - however I think my situation may be a little unique.

I'm configuring 2* SSG 20s for a 2 site VPN setup - and I'm in the process of configuring the port forwards so that each site can rdp eachother etc etc. Simple enough.

The SSGs have been fitted with an adsl2/2+ A PIM each to accommodate the links at each site - here's where I *think* I may be having an issue.

I'm fairly new to Juniper products - so I'll try to explain my problem as best as I can.

I'm familiar with the VIP method - however I'm unable to see the VIP option on my adsl1 untrust interface - I do however see it on the bgroup0 trust interface - however I'm thinking this is the incorrect interface to configure VIPs for my requirements.

Reason I'm confused is that I use a 5GT at home - and I have configured VIPs quite easily on the untrust interface with no hassles, I created my custom service, setup my policy, chose the VIP as destination - off it went without a hitch.

The SSG20s are being configured offsite ready for deployment tomorrow - adsl interface is as yet not initialized - could this be why the VIP option is missing?

I'm thinking it has something to do with the PIM/dsl untrust interface configuration - although I accept I could be way off. I followed the manual and there's nothing really specific about the PIM install/config.

Any help or a point in the right direction would be handy. I'm waiting for my 1 day turnaround to activate Juniper support for these new SSGs hence I've posted for help here.

Look forward to some assistance.

Thanks

Nick

You are correct, the VIP needs to be defined on the untrust interface, ie the public side.

Is there any way you can enable the DSL interface at all just to see if the VIP option makes itself available and I will also have a wee look to see if there are any gotchas with ADSL and VIP

What version of screenos you running bud?  Am still looking for any ADSL gotchas, but all I can see at the mo is that is should just work, but if you dont have the option there ) ie its not listed, then its a bit odd.

I would try to active the interface to see if it makes a diff cos that may be stopping us here.

See the article below which gives a bit more confirmation that we should be able to get this done.

http://kb.juniper.net/KB5571

Can a Virtual IP (VIP) use the same IP address as the untrusted interface?
Knowledge Base ID:       KB5571


Synopsis:
Can a Virtual IP (VIP) use the same IP address as the untrusted interface?  Which Firewalls support "VIP same as Untrust"?

Problem:

    * Virtual IP Only have 1 Publicly available IP address
    * Allow access to internal servers using the same IP address as the untrust
    * Cannot set VIP as the same IP address as Untrust interface
    * Which firewalls support 'VIP same as untrust'?

Solution:

ScreenOS 6.0 and below:

VIPs can only be defined in the Untrust zone.
VIP Same as Untrust IP feature is supported on the lower end platforms. These include the following:

    * NetScreen-5
    * NetScreen-5XP
    * NetScreen-5XT
    * NetScreen-5GT (including ADSL and WLAN versions)
    * NetScreen-HSC
    * NetScreen-25
    * NetScreen-50
    * SSG-5 (all variants)
    * SSG-20
    * SSG-140
    * SSG-320M
    * SSG-520 (and SSG-520M)


ScreenOS 6.1 and higher (applies to all models):

    * You can configure the virtual IP (VIP) address as the same as the interface IP address on any device in any zone.
    * You can configure the VIP and mapped IP (MIP) address on the same interface using the same IP address. This allows you to selectively redirect traffic for specific applications to designated servers.
    * You can configure VIP, MIP, and dynamic IP (DIP) addresses in any combination on any interface.

New CLI command:    set interface <interface-num> vip interface-ip <port-number> <service name> <IP address>


Refer to the following KB for the models that support the 'MIP same as untrust' feature:
KB11167 - MIP can use the same address as an interface in some models

Additional information:
 KB14223 - Limitations to Services that Can Be Used for VIP Same as Untrust or VIP Same as Interface IP

Unfortunately I cannot initialize the connection until I'm at the actual site.

I can confirm it's firmware version 6.1.

I think you may be onto something though - I'm going to try your suggestions first thing when I'm onsite in the morning.

I'll post feedback as I go along.

I appreciate the prompt response Deimark.

 

by: deimarkPosted on 2009-08-06 at 06:43:04ID: 25033186

6.1 should definitely do this bud, but as I have not had the pleasure of the ADSL interface in my SSG20s, its the only unknown in my books.

I should be online for most of tomorrow bud if you hit any issues.

The issue was indeed caused by the dsl interface not being initialized and having an IP at the time I configured the units.

Soon as I arrived onsite - connected the units and the interface established a connection with an IP address - the VIP option became available. The rest was reasonably easy to complete and the VPN is now simmering away nicely.

Thanks for your help Deimark it certainly propped me up.

Cheers!

Nick
