Previous attempts to set up these NAT rules has been met with minimal success. We have been able to get the NAT rules created, and able to ping our inside servers and receivers from a different outside network, but every time we get that far our internal network crashes. Running the Packet Trace utility via the ASDM shows that internal traffic from the servers to the workstations is being blocked by the default implicit rule under the access rule heading that states "any to any, service being ip, action= deny". Reverse traffic from the workstations to the servers is being allowed though. In an effort to start over again, the Cisco ASA has been Factory Defaulted via the CLI, and has had it's Inside network, and Outside IP address set back up. DHCP pool has been setup for a minimal amount of addresses on the inside network, since most of our equipment will always be assigned statics. We reset our static NAT policies, and seem to be having the same problem. My partner and I have been working on this for some time now, and have ourselves so frustrated that I know we are missing something simple. Any help will be greatly appreciated.
Embarq : Network xxx.xxx.180.104
Gateway: xxx.xxx.180.105
Subnet Mask: 255.255.255.248
Our Static IP's: xxx.xxx.180.106 to xxx.xxx.180.110
Cisco Pix for VPN tunnels : xxx.xxx.180.107 outside IP
used for DataBase Servers : 100.1.0.2 Inside IP/ Gateway 2
Cisco ASA 5505: xxx.xxx.180.106 outside IP
all other traffic : 100.1.0.1 Inside IP/ Gateway 1
Inside Network: 100.1.0.0/24
Application Server: 100.1.0.115 uses Gateway 1
BackUp AppSrvr: 100.1.0.116 uses Gateway 1
DataBase Server: 100.1.0.113 uses Gateway 2
BackUp DBSrvr: 100.1.0.114 uses Gateway 2
Cobox/Receiver: 100.1.0.140
BackUp Cobox: 100.1.0.150
Workstation 1: 100.1.0.112
Workstation 2: 100.1.0.111
Network Speaker1,2,3,4: 100.1.0.125 to 100.1.0.128
Future Workstations: 100.1.0.0/24
1. Embarq Gateway feeds both Cisco Pix, and Cisco ASA. Both Ciscos feed a Dell Switch.
2. All inside network devices at 100.1.0.0/24 are networked into the Dell Switch.
3. All Workstations/Network Speakers need to be able to communicate with all four servers, and the Cobox/Receiver.
4. The DataBase Servers have VPN tunnels created in the Pix for clients to be able to login securely and edit their account info.
5. The App Server (100.1.0.115), and BackUp App Srvr (100.1.0.116) need to have a NAT rule created NAT'ing them to xxx.xxx.180.109.
A. The xxx.xxx.180.109 NAT rule needs to allow ALL UPD traffic TO and FROM ANY outside IP address.
B. The xxx.xxx.180.109 NAT rule needs to allow ICMP traffic FROM ANY Outside IP address.
6. The Cobox/Receiver (100.1.0.140) and BackUp Cobox (100.1.0.150) need to have a NAT rule created NAT'ing them to xxx.xxx.180.108
A. The xxx.xxx.180.108 NAT rule needs to allow UDP traffic FROM ANY Outside IP address source port 6000 or 9000 to destination port 9000
B. The xxx.xxx.180.108 NAT rule needs to allow ICMP traffic FROM ANY Outside IP address.
7. Right now the Cisco PIX is functioning and working perfectly for our VPN tunnels.

OK - so how many devices on your LAN access the internet and send traffic out to the internet, this should included servers, routers hosts etc.
If the number you have is more than 10 - that's your issue. You are ONLY licensed for 10 inside hosts, you will need to upgrade your license.

What license does the ASA5505 have?
01-09-2012 07:23 AM
Thank you for your query. I just got into the office. I am going in to login to the ASA and double check the license.
01-09-2012 07:25 AM
Ok. Our ASA has a "Base" license.
01-09-2012 07:34 AM
How many inside hosts are you licensed for?

Ah-ha Ok I think I see. If we have more than 10 inside IP addresses, then the ASA is only routing traffic for 10 IP's, so....
any other traffic is potentially being ignored, or dropped.
Would this affect inside to inside traffic also?
01-09-2012 08:36 AM
If the ASA is being used as a sort of router in/out the inside interface, then yes this would also be affected. To get around that particular issue would be to have a dedicated layer 3 routing device on your lan.

OK. Thank you very much for your help. I am going to get with the powers that be to upgrade the "Base" license in this ASA.
In the meantime I will Close and Rate this post for now so others can get this info also.
If we have any further issues after the upgrade, then I will open a new post.
Thanks again. We new it was something simple. Not sure how we overlooked that, but hey we're getting somewhere now.
