Segment from PIX to segment on ASA

Tyler Woods
Level 1
Level 1

I need the following to happen:

Host at 12.x.x.134 to access host 10.50.2.32 on port 8888.

Host at 12.x.x.134 to access host 10.50 2.33 on port 1560.

I am at a complete loss on getting this accomplished. Have tried multiple configurations and nothing works. Ideally I would collapse this all to the ASA but I do not have the time to dedicate at the moment so I just need to get this working as it is. The ASA is under SMARTnet but CCO ID does not have permission to its serial number yet.

Any guidance on this would be greatly appreciated. Is below enough to go on?

ASA Interfaces

Ethernet0/0 outside 64.xx.xx.130 security-level   0 --> to RouterA via 2980

Ethernet0/1 inside  10.50.2.1    security-level 100 --> to 2980

Ethernet0/2 dmz1    10.10.10.2   security-level  50 --> to ASA e2

PIX

Ethernet0   outside 12.xx.xx.2   security-level   0 --> to RouterB via 2980

Ethernet1   dmz     12.x.x.129   security-level  50 --> to 2980

Ethernet2   dmz2    10.10.10.1   security-level  50 --> to PIX e0/2

That should be the route on the ASA correct?

They are different subnets. That is why for the outside interface I used two "x" instead of one to differentiate. Sorry for the confusion.

Yes that route would be on the ASA because it uses it's dmz1 interface to reach the pix.

You could actually test with just one host route rather than use the 12.x.x.x subnet and see if that host works.

Jon

So given the NAT statements I put in already using that route should work? If that is the case I'll give it a try with a single host right now.

Yes, you will need the original config posted + that route.

Try it and let me know.

Jon

I have made the changes and asked for that site to give it a try. They may not get to test till tomorrow as it is 5:30 PM their time.

Thank you Jon for all your assistance on this.

No problem. Let me know how you get on and if it doesn't work then we can carry on troubleshooting.

Jon

Still not working. With goof I made with route on the ASA I applied that same logic to the route on the PIX.

This is what I had:

route dmz 10.50.2.0 255.255.255.0 10.10.10.2

Changed it to:

route dmz2 10.50.2.0 255.255.255.0 10.10.10.2

Neither has made this work.

Tyler

Did anything break when you added the route to the ASA ?

When you try to connect from a 12.x.x.x host do you see any hits on the acl applied to the ASA dmz1 interface ?

We need to work out where the traffic is failing.

Jon

Nothing broke thankfully.

The route I have on the ASA is: route dmz1 12.10.100.134 255.255.255.255 10.10.10.1

Route on the PIX currently: route dmz2 10.50.2.0 255.255.255.0 10.10.10.2

These ACL entries are applied to the dmz1 interface on the ASA:

access-list DMZ2IN line 4 extended permit tcp host 12.10.100.134 host 10.50.2.33 eq 1560

access-list DMZ2IN line 5 extended permit tcp host 12.10.100.134 host 10.50.2.32 eq 8888

I have these static NATs in place on the ASA:

static (inside,dmz1) tcp 10.50.2.32 8888 10.50.2.32 8888 netmask 255.255.255.255

static (inside,dmz1) tcp 10.50.2.33 1560 10.50.2.33 1560 netmask 255.255.255.255

Based on the orginal diagram that config should have worked. Like i say we need to understand where the packets are getting dropped.

So first we need to work out if the packets are leaving the pix on the right interface. Easiest way to do this is look at the acl on the dmz1 interface of the ASA and make a note of the counters for the relevant line. Try and connect and see if the counters increment. If they do we know that packets are going through the pix correctly.

Jon

Apologies, I failed to answer that earlier. The counters have remained at zero.

Do you have any acls applied to the dmz or dmz2 interfaces on the pix ?

Jon

The following is applied to dmz2; both with no hit counts.

access-list temp_inside extended deny ip any host 89.x.x.x log

access-list temp_inside extended permit ip any any

Sorry i have should asked this in the last post. Can you post any NAT config for the dmz and dmz2 interfaces on the pix ?

Jon

I'm wondering if that may be the issue. Just not well versed enough to know for sure.

PIX NATs

nat (dmz2) 0 10.50.2.0 255.255.255.0

ASA NATs

nat (inside) 0 access-list NONAT

nat (inside) 1 10.50.2.0 255.255.255.0
