Question

PIX 506 from 5.1 to 6.3 with PDM

Asked by: rcurrie01

I inherited two PIX 506 Version 5.0(2) firewalls that used to be in two separate offices connected by a vpn tunnel.  I need to upgrade both, one (production) and another that I use for a backup.  The production config works fine (old consultants set it up with a lan-to-lan to their 3000 concentrator for remote troubleshooting, that needs to be done away with, otherwise pretty basic, one e-mail server with OWA and a remote access vpn policy that can stay).  Another caveat is that we currently use the old Sonicwall vpn client that is not compatible with XP and I would like to use the cisco vpn client 3x.  Trouble is I have never configured them before.  Assuming I have no Smartnet for either (if I even need it) what would be the easiest way to upgrade both.   I can use the backup for practice, then switch with production when I get the config right.  Thanks for your help...

Have you got a hold of the software? You can configure the Pix to accept VPN coneection from clients you could use that cisco vpn client software on the XP machines. If you are going to upgrade make sure that your remote client set-up is using a different access-list than the Lan to Lan tunnel.
This is what you need to set up on the Pix for the VPN clients

access-list vpnlist2 permit ip 192.168.3.0 255.255.255.0 192.168.6.x 255.255.255.224
access-list vpnlist2 permit ip 192.168.4.0 255.255.255.0 192.168.6.x 255.255.255.224

I don't have any of the software.  I suppose that it is a problem.  I don't have the Smartnet's either.  I have a couple of questions on the cli portion above...

 - I would need to do this config after flashed the pix with the upgraded ios version?

 - access-list vpnlist2 permit ip 192.168.3.0 255.255.255.0 192.168.6.x 255.255.255.224
access-list vpnlist2 permit ip 192.168.4.0 255.255.255.0 192.168.6.x 255.255.255.224
I don't understand why both are here, shouldn't there just be one, say the first one.
 
 - ip local pool client 192.168.6.x-192.168.6.x
This should be different then my internal nat, right?  So if my internal addresses were 192.168.3.x for instance, I could use anything else for my pool?

- vpngroup vpnmyclients dns-server 158.43.x.x 158.43.x.x
vpngroup vpnmyclients default-domain whatever.com
vpngroup vpnmyclients split-tunnel vpnlist2

On the DNS server, is this my particular internal DNS server addresses?
On the default-domain, is this just the domain name?
On the split tunnel, is this why there are two addresses ranges, does it split up the addresses between the two to provide for more concurrent accesses?

Sorry about all the questions, I don't know my arse from my elbow with this stuff...

Here is another question...Depending on the cost of the smartnet for the software, should I just dump both Pix's and get a new firewall with better functionality, etc.  I would like to have failover and I know the Pix 506 doesn't support it.

 

by: snoopy13Posted on 2004-03-12 at 07:39:51ID: 10581343

Not having the software will be a problem if ou want to upgrade, but why do you want to upgrade?

You would telnet to the router and then apply the config no need to upgrade to do it.

If you have only one internal address you would only have one access-list.

The pool should be something else than your internal address but you will need to add a route on your interanl address for that subnet via the Pix.

DNS would be the dns that you use whether internal or external.
Domain that would reflect your domain name.
Split tunnel allows local internet access so the client would come to the lan for any internal destined traffic and break out locally for internet access.

Smartnet is not cheap but I am a teckie and not familiar with the exact costs
Pix 506 does not support failover you would have to go to a 515 failover pair.

 

by: rcurrie01Posted on 2004-03-12 at 08:00:17ID: 10581546

Two reasons for an upgrade.  

A - Have never configured PIX by CLI, and figured it would be easier by using the PDM.  
B - Currently using old Sonicwall VPN client, which doesn't run on XP, and all of my clients are XP and they need remote access.

I did a Write term and the contents are below.  Everything that I think is from the old consulting firm is delineated with a NOT APPLICABLE.  I need to strip out what I don't need.  This is the production PIX, and everything works fine.  I need the backup PIX to have this same config, so I need to know how to do that also.  I also found a Cisco VPN client 3.5, will that work with XP and this version of PIX?  Maybe I don't have to upgrade the IOS after all.  :)

Everything is currently configured ok, here it is...

3.5 that is an old version I know that there was a version for 2000 not sure about XP you will have to try it.

If you want PDM you will need to upgrade.

You can simply save this in a text format somathing like notepad and copy and paste the text into the new Pix you must be in config mode. If you are going to do this do not copy the whole text body in one go break it down in sections.

I cannot however tell you what needs removing, not being familiar with your set-up.

 

by: tim_holmanPosted on 2004-03-15 at 10:50:53ID: 10599749

If you can't upgrade, configure PPTP client on the XP client, and the PIX as a PPTP server:

http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a0080093f89.shtml

This config is supported on PIX 5.1 upwards.

It will be the cheapest way out for you !

 

by: rcurrie01Posted on 2004-03-15 at 12:20:19ID: 10600597

Would the solution from snoopy (Comment from snoopy13
Date: 03/12/2004 02:53AM PST) be better or tim (Comment from tim_holman
Date: 03/15/2004 10:50AM PST)?  I think that the 3.5 client works fine on XP, I don't mind not having the latest version.  I just need config help inserting the correct commands and deleting the old vpn tunnels to the consultants office...See above PIX code...

VPN client compatability list is here:

http://www.cisco.com/en/US/tech/tk583/tk372/technologies_tech_note09186a0080094e6d.shtml

Windows XP with any version of VPN client (Cisco or native PPTP) will only work with PIX 6.0x and above.

Cheapest Smartnet for a PIX 506 is $190 (without any discount) -

SP-SW-PIX506      SP Base Svc, For Pix-506      $190
