Is there a cisco best practice on the maximum number of NAT statements on a Cisco ASA? We have a 5520 and a coworker is adding static NAT policies so a vendor can monitor around 1,029 nodes. The problem is each node inside is a 10.X.X.X and to keep the IPs from overlapping with other customers the vendor monitors they would like us to NAT to a 172.16.X.X scheme.
View 3 RepliesI have a asa 5520 with an outside and backup interface. I am trying to configure two static nat statements from the inside to the outside and backup interface. Here is what I have configured so far.
object network obj-10.1.1.254
host 10.1.1.254
object network obj-10.1.1.254
nat (inside,outside) static 172.25.10.3
I want to also use nat (inside,backup) static 172.25.10.3
I have a FWSM cluster that I exceeded the maximum number of static nat entries on. i migrated the connectivity off to a pair of PIX 535's that seem to be handling the adderess translation needs. however the number of NAT entries being required is increasing and being the PIX series wal EOL'd several years back..I need to replace them.. The static 1-1 nat entries cannot be summarized into network as the hosts that are being nat'd are scattered all over various micro subnets in the all 3 rfc1918 ipv4 address ranges and they are being manged directly by snmp and SNMP-trap and other services that prohibit the use of many-to-one nat. Is there a mknown maximum number of static 1-1 nat entries that can be defined on the ASA 5515-x, 5525=x and higher ASA firewalls? Say I wanted to be able to grow to 2500 or more static 1-1 nat entries. I am currently running 2010 1-1 static host nats currently.

View 5 Replies View RelatedI have a faulty ASA5520 and I am not sure if I have a SMART net contract for it or not (I manage over 200+ ASAs). The problem is that the Serial Number sticker that is normally on the back of the ASA is missing. The ASA5520 is also faulty and doesn't power on so I cannot boot it up and run 'show ver' or similar. If I open the chassis there appears to be other Serial numbers on the Power Supply, and Motherboard etc but they do not seem to be the correct Chassis serial number i.e not in the right format, and if I put them into the Trade tool I get no results.
There must be another record of the serial numbers besides 1x sticker to the rear of the chassis that can fall off? How I can get the chassis serial when the device isn't booting. or (Cisco) is there a way to find the chassis serial number from the power or motherboard serial?
The configuration for the natting is something like this [code] If I understand the config statements 10.232.50.98 is natted to 32.x.x.66 and 10.232.50.99 is natted to 32.x.x.69 , but do we need reverse natting stements as well to work this ?

View 1 Replies View RelatedWe are having random issues of users not being able to connect to our wireless network consistently. The users will have successfully accessed the network previously but then will have difficulty associating to the network. After a period of time, the association appears successful again. My first thoughts were that there was a restriction on the number of clients that could associate to a given AP at any one time.This is the equipment we have:1x Cisco Wireless Control Server (WCS) 6.0.181.04x Cisco 5508 Wireless LAN Controllers 6.0.196.060x Aironet 1142N Lightweight Access Points (LAP) Is there a hard or recommended maximum number of clients per LAP? If so, where is this defined? From what I have read on these forums, Cisco apparently recommends about 25 clients per AP but I can not find any official documentation to support this.When I go to WCS Home > General > Top APs by Client Count, the top AP reports 20 clients. However, if I click on the AP Name and go to the Current Associated Clients tab, it is only listing 8 clients - why is this?

Interface vlan544 (172.16.80.0/24) is the local encryption domain, and 10.1.0.0/29 holds some monitoring servers that should not be part of the encryption domain, but rather get it's source address translated to that of the firewall in 172.16.80.0/24. Here's how I did:

Is that correct? Also I'm using one public address to PAT both inside networks. Is there any dvantage of using 2 different ones, so each inside network would be PAT to its own address?
I have a Cisco ASA running 8.2 in routed mode.The ASA has three interfaces, inside, outside and DMZ. They connect to the following three networks:
Inside: 10.1.1.0/24
Outside: 10.1.2.0/24
DMZ: 100.1.1.0/24
I have the following dynamic PAT configuration:
nat (inside) 1 10.1.1.0 255.255.255.0
global (outside) 100.1.1.1
nat control is turned off.
By my understanding any traffic from the inside to outside interface will be PATted to 100.1.1.1. However, communications between inside and the DMZ will not be PATted, and should work with no problems.This seems to be corroborated by this document: [URL]Which states:"The adaptive security appliance translates an address when a NAT rule matches the traffic. If no NAT rule matches, processing for the packet continues."EDIT: I may have misunderstood the above statement.I found this guide to configuring NAT/PAT: [URL]It states:"When you specify a group of IP address(es) in a nat command, then you must perform NAT on that group of addresses when they access any lower or same security level interface; you must apply a global command with the same NAT ID on each interface, or use a static command. NAT is not required for that group when it accesses a higher security interface because to perform NAT from outside to inside you must create a separate nat command using the outside keyword. If you do apply outside NAT, then the NAT requirements preceding come into effect for that group of addresses when they access all higher security interfaces. Traffic identified by a static command is not affected."My problem is that packet tracer does not seem to bear me out. It tells me the packet is dropped due to "no matching global" when I source traffic from the inside interface and send it to the DMZ.
I have a question regarding to the maximmum number of active SSID's on a WLC 5500 with 3500i, it's my understanding that the 3500i can support 16 active SSID's is it the same when connected to the WLC? Also, if possible would the WLC shutdown un-used Radios or maybe after hours?

What are the maximum number of AE2500 wireless adapters can be installed on a PC running Windows XP SP3 using the windows wireless zero configuration? Recently I'm working on a program that needs multiple seperate wireless connections on a Windows XP SP3 PC. Each wireless adaptor is given a static IP address to respond to traffic at some specific ports. I can install four AE2500 adaptors without problem, but it disconnects the first AE2500 device when I plug in the fifth AE2500 adapter. I've tried on different windows XP machines. They all get the same problem. I wonder if it is a limitation in the AE2500 driver.BTW I've also tried to install an Valet AM10 adaptor as the fifth adapter, it seems ok. Yet installing more AM10 adapters beyond the fifth (4 AE2500 + 1 AM10) requires some luck. It may disconnect the other AM10 devices when I plug in another AM10 adapter.
