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
Solved! Go to Solution.

How easy is it to make config changes and/or do some debugging. The fact that the ASA dmz1 acl applied inbound has no hits suggests the pix is not sending the packets. So we can either -
1) apply an acl outbound on the dmz2 interface of the pix -
access-list dmz2_out permit ip host 12.10.100.134 host 10.50.2.33
access-list dmz2_out permit ip any any
this should not block any traffic we are just seeing if the first line gets a hit when you try and connect
or
2) we can debug the pix interface and see if the traffic is leaving the interface

access-list dmz2_out extended permit ip host 12.x.x.134 host 10.50.2.32
access-list dmz2_out extended permit ip host 12.x.x.134 host 10.50.2.33
access-list dmz2_out extended permit ip any any
access-group dmz2_out out interface dmz2
I put the above on the PIX and got some hit counts increased when they tested going to 10.50.2.33.
Debugging shouldn't be an issue. Just have never done it so will need to be very careful when I do it.
11-21-2013 12:42 PM
So you got hit counts when you tried the connection but still no hit counts on the ASA inbound acl on dmz1 ?
That doesn't make any sense if they are connected on the same network.
Jon
11-21-2013 12:45 PM
That is correct. No clue as well as you can see. Not sure what I am missing here.
11-21-2013 12:51 PM
Lets assume the issue is with the ASA for the moment. We may need to do a packet capture but is there any change of posting full ASA config (minus any public IP info) ?

Here it is sanitized fully I believe.

From the config -
access-list DMZ2IN extended permit tcp host 12.x.x.130 host 12.y.x.130 eq ftp
access-list DMZ2IN extended permit tcp host 12.x.x.130 host 12.y.x.130 eq ftp-data
access-list DMZ2IN extended permit ip any any

access-list DMZ2IN extended permit tcp host 12.x.x.134 host 10.50.2.32 eq 8888
this is probably why we aren't seeing any hits because the lines for ports 1560 and 8888 are after the permit ip any any and will never be reached. There is a good chance the packets are arriving and being allowed through on that interface. So lets assume they are.
global (dmz1) 1 interface
nat (inside) 1 10.50.2.0 255.255.255.0
static (inside,dmz1) tcp 10.50.2.32 8888 10.50.2.32 8888 netmask 255.255.255.255

we also have a conflict with our NAT statements. You are natting the 10.50.2.x addresses to IP of the dmz1 interface ie. 10.10.10.2. Do you know why this is being done ?

I show no hit counts on:
access-list DMZ2IN extended permit ip any any
I have no clue why that is being done nor understand the purpose.

The ports are defintely TCP and not UDP ?
Can you post the output of this command from the ASA -
sh xlate interface dmz1

I have asked them about TCP vs UDP and will reply when I have an answer back.

What i would like to do is -
1) reorder DMZ2IN acl so the last 2 lines are before the permit ip any any
2) then clear those translations ie.
clear xlate global 10.50.2.32
clear xlate global 10.50.2.33
3) retry the connection and see
a) if the hit cnts increase on the pix
b) if you get any hit cnts on the DMZ2IN acl
trouble is i'm not sure why those global and NAT statements are there in the first place. It could be disruptive to traffic but i don't know what else is travelling between these two interfaces (if anything). What do you think ?
If not we may have to do packet captures and these can be quite disruptive to the firewalls so its best done at a quiet time.
If you are happy to do the above can you first post -
sh xlate global 10.50.2.32
sh xlate global 10.50.2.33
from the ASA

DMZ2IN has been re-ordered.
Issued the clear commands.
Connections are still unsuccessful.
Hits increased on the PIX but not on the ASA.
Here are the results from those show commands:
show xlate global 10.50.2.32
508 in use, 2506 most used
PAT Global 10.50.2.32(8888) Local 10.50.2.32(8888)
show xlate global 10.50.2.33
565 in use, 2506 most used
PAT Global 10.50.2.33(1560) Local 10.50.2.33(1560)
As far as the global NATs go I am not knowledgeable enough to answer that. The ASA plugs in to device providing them access to the Internet via a fiber provider that I have no access to. My thoughts were they NAT the 10.50.2.0 to that outside interface for Internet access.

Okay, clear those translations -
clear xlate global 10.50.2.32
clear xlate global 10.50.2.33
as they only refer to the ports we are talking about.
Then can you post - sh xlate interface dmz1
and retry connection.

Cleared.
Tested and it doesn't work.
