Network Supernetting/Subnetting Change

do you have switches that can handle VLANS because instead of changing the config keep te /24 subnets and add additional ones in and route to them

There will be switches installed within the next week, 2 Cisco 3750x's are going to be installed along with a NetApp SAN and VMWare hosts.  I was thinking the PIX wasn't able to handle multiple subnets/VLANS for NAT to the internet.

it will support VLAN's i think it will only support 2 but that would be the way to go to expand you network. You could add a second large VLAN until you are able get an ASA or something in

The changes to the firewall are what I am trying to avoid here.  I am not very well versed in the workings of the Pix, we currently have a vpn tunnel established to a redundant site in Texas (we being in Illinois) and i don't want to lose my connectivity to that site and I really wouldn't know the first thing about configuring that tunnel.  In the long run we will be removing the pix from the network.  I would like to create a completely different subnet such as a 10.x.x.x on with the new equipment and retain the ability to communicate with the existing network, eventually migrating to the 10 subnet completely.  Does this sound possible with the 3650x and Pix506e in place?

Firstly I doubt without changing anything on fw you can accomplish network re-numbering. We can help if you can post us the fw config

Once you have switches in place , you can create subnets and manage wasted ip addresses if any or creAte a new scheme, but that would mostly call for a change in fw's config ad well

Regards
PG

I'll post the FW config shortly if you all can help me.  I can put together a small window of time where I can restart the firewall, but rebooting the servers will be the hard part until mid march.

Pix config as of today, IP's redacted for security reasons....Thanks for the help...

So an update to what I need to learn and accomplish in 2 weeks.  Configure 2 x 3650x switches with 3 VLANS and layer 3 routing back to the PIX.  192.168.1.1/24, xxx.2.1/24, xxx.3.1/24.  1.1 being the VLAN setup for existing users, 2.1 an iSCSI network for VMWare/NetApp SAN and 3.1 VLAN for the VOIP.  

I am familiar with Cisco, so I do have a clue, but some guidance into the iscsi realm as well as VLAN routing on these switches would be of help to me.  Beyond the core switches are Cisco SB 500 switches for the workstations and phones.  These will be connected via fiber GBIC modules.

My understanding first is to re address the PIX to 192.168.1.2 then make the core switch 192.168.1.1 and enable iprouting between the VLANS and the pix out to the internet.

So here is what I came up with so far on my 3750x stack...can someone tell me if this is close at least?

Hello,

I see the vlan SVI's addition, how ever i pre-asume this i the sw config, what interfaces are going into these vlans and do you have any trunks ?

in the firewall, how do you provision an ACL or matching criteria for 2.0 and 3.0 ? This is what i was speaking about in the previous case, without adding 2.0 and 3.0 subnets , how do you match the traffic  ?

Are you hoping to do any inside NAT ?

Thank you
Game

I'll try and break this down as simple as possible:

VLAN1  will be the current flat network we are on with 192.168.1.0/24 which is currently handled by the PIX and does the NAT to the internet.

VLAN2 will be an iSCSI network segmented away from the other VLANs for VMWARE/SAN [

VLAN3 will be for future expansion, growing beyond the original subnet is an upcoming reality.

What I need to accomplish is to insert these new switches into the network and give them the ability to take over routing from the pix506e.  In the current environment the issue is age old software that is in the midst of being updated, but it's proprietary and has hard coded IP addresses in it.  This presents the problem of not being able to subnet this network properly at this time.

My understanding is that I can create the VLANs on the 3750x switch stack and have them do the inter-vlan routing, taking the 192.168.1.1 gateway address from the pix and re-addressing the pix as 192.168.1.2, making it the default gateway for the switch.

I do not have any trunks because this is beyond my experience level.  I have since changed the switch config as I have read a bit more about this.  Currently the most important step of this is to be able to insert these switches into the network, then connecting a Cisco 2960G and 4 Cisco Small Business 500 switches all by fiber and have them pass traffic.

VLAN3 is for future expansion and will need to be able to route to the pix as well as see the VLAN1 network.  VLAN2 only needs to see itself and the devices attached to it.

So you topology is something like below

 INTERNET ---- PIX ----- LAN -> previous topology
 INTERNET -----pix------3560------distributed lans ---- new topology

and hence you will have IVR between distributed labs by having svi on 3560's for vlan 2 and if possible for Vlan 1 (for traffic to same subnet) and any other traffic would hit pix  ?

If this is the case, I see the proposed design by you is good enough to go , if not please post in the topology and we shall discuss.

Please remember for the fact that, physical ports should be mapped to specific vlans, which i have not seen in your configuration and may be a default route for vlan1 pointing out to pix interface, assuming above topology

Thanks

Yes, you have nailed my topology old and new.

INTERNET------PIX--------3560----------distributed LANS

Currently the 192.168.1.0/24 is the only subnet used on our network, which is fine as we are a small shop, what I am trying to accomplish is to create the VLANS and IVR for expansion.  Eventually I will have the ability to resubnet this whole network in the summer when we are slow, but for now I felt this was the best researched solution I could come up with.  

Here is the latest and what I hope to be the final config for the switch, although I do believe there are some changes I will have to make on the pix in order to route VLAN3.

Again the Pix will change to 192.168.1.2 and the switch will take over as the default gateway for the network at 192.169.1.1.

Hello ,

You have interface vlan 1 , it will not be up unless otherwise a physical port is going towards it , and by the way why  do you want to change the ip address on switch and pix ?

Apart from that looks good to me

Regards
Rakesh M

The PIX 506e does not have the capability to do the VLAN routing, therefore I intended on using the switch to do the layer 3 routing.  I don't want to change anything to be honest and would prefer to be able to keep the pix as the router.  I am not familiar enough with the pix to accomplish this.  The first 6 ports on the 3750 (gi1/0/1 - 1/0/6) are designated as VLAN1, although it's my understanding that by default all non-specified ports default to VLAN1.

If there is a PIX expert out there that can show me a better way to accomplish IVR with the pix instead of the swtich, I'm all for that.  My budget is exhausted as is my brain and the maintenance window for installing this switch is Thursday from 4am to 6am CST.

I would say everything is good at this point from your design perspective, but again i can only suggest wrt to routing and switching and partly security, Without many changes on pix this is the way to go, I would await anyone from security expertise of pix to comment about modifications

Good luck with implementation

Regards
Game

Thanks,
   Eventually we will replace the PIX with an ASA, but until we decide on our redundant offsite strategy, which is currently a COLO with a pix to pix VPN tunnel, I don't want to spend the money on 2 ASA devices when we may only need one if we choose a NetAPP equipped hosted site with an MPLS or other routing solution that will not require that VPN tunnel.  The ASA 5510, which is my choice for our firewall upgrade, will not tunnel with the old PIX 506e at our redundant site.
 I'll be inserting this switch into the network tomorrow and hope everything comes back up without a hitch.

Thanks for all the advice and help!!

So as an update to what I did, I started at 4am today and by 4:30 I was routing through my switch stack instead of the PIX.  Now to get VLAN3 to route to VLAN1 and vice versa and the only thing left after that is creating the etherchannel ports for the ESXi hosts.

Thanks again for all the help and positive reinforcement.
