I have an ASA that is logging the message %ASA-3-321007: system is low on free memory blocks of size 2048. I ran the "show blocks" command and the "Cnt" value for the 2048 blocks is 0. How do I reclaim these blocks and what are they used for?

I have an ASA5510 running version 8.4. ICMP is blocked from the internet to the outside interface of our firewall but now our ISP is requesting us to allow ICMP from their network to the outside of our ASA. I need to allow ICMP from three blocks of IP Addresses?
View 9 Replies View RelatedI am having trouble with our ASA5510. After upgrading the internal memory from 256 MB to 1 GB and upgrading the firmware to 8.4.2 we are experiencing that the ASA is running out of 1550 byte blocks. When that happens it is not possible to connect to the ASA by ADSM or SSH and new VPN IPSEC tunnels are not coming up. The only way I know how to fix this is to reload the ASA. This is happening every 2 to 3 days.
In the free blocks graph one can see that there is a loss of about 20 blocks per 10 minutes.
I have installed a new ASA5510 with CSC, and everything is working properly except the access to websites using https. All sites/access to them seem to be blocked by the ASA. I have read that this access is by default enabled and I have tried to add configuration to allow https access to the firewall but without success. [code]

We want to run ASA 8.4.x on an old ASA5540. We need to upgrade its memory to 2 GB with the following memory upgrade: ASA5540-MEM-2GB=
I suspect that we will completely remove the existing 1 GB of memory and replace it with 2 GB. If this is the case, can I use this 1 GB of memory removed from the ASA5540 and put it in a ASA5510 instead of buying a ASA5510-MEM-1GB= for the ASA5510?
We recently added about 400 users to our network for a total of 1000. Looking at the ASDM we are holding very tight to 75% utilization and we have 256mbs. This is also running IOS 8.2(1). Our firewall recently crashed after a major download was forced through it. This was after only being booted up for about a week. We had reloaded it a week prior after having ran it for about a year without issue. We havent made any changes in the last month other than adding more users to our network.

View 6 Replies View RelatedI have an ASA 5510 running 8.4(2) which has a site to site IPSec VPN to a 3rd party who run some form of Checkpoint. The VPN establishes and allows access to a server in our DMZ on all ports that we have tested (so far HTTP, SSL, RDP, FTP) except for SQL which doesn't even seem to reach the server. I've got Wireshark running on the DMZ server and if the 3rd party initiates a TCP conversation from their server on any of the working ports to the server I see all of the expected packets arrive with the correct IPs etc (no NAT takes place across the VPN) but when an ODBC client attempts to query the SQL server on our DMZ box the packets do not arrive at the server. What I can see is the RX byte count on the VPN increasing each time the query is run but definitely no SQL arriving at the server.
Also if I revert the ASA back to the old PIX it has replaced with the same VPN config but on version 7.x then it works just fine.
Currently I have an asa 5510 set up with one block of outside IP addresses. Everything is working fine in regards to my initial setup. However we needed to purchase additional IPs from our provider and ended up being a whole complete different block. Where I am getting stuck is getting the new IPs to NAT to inside addresses.
View 2 Replies View RelatedI am doing the initial configuration on our ASA 5510 to use our Radius server just as our 3005 VPN Concentrator did. I can do the test connection inside the ASA with no problems, and when I authenticate using the Anyconnect client, it appears to authenticate fine, but then dumps the connection with an error stating there is not enough memory in he ASA to allow this connection, the error message is as follows:
Error Message %ASA-4-722004: Group group User user-name IP IP_address Error responding
to SVC connect request.
Explanation There is not enough memory to perform the action.
Recommended Action Purchase more memory, upgrade the device, or reduce the load on the device.
Can this really be the case with no connections active, a single user attempting to authenticate through Radius and an out-of-the-box ASA 5510?
I am trying to load the anyconnect VPN client package v3 for windows and Mac on ASA 5510. The ASA has 256MB for RAM and Flash. After I uploaded pkg files and selected the 2 files and applied from ASDM, ASDM spots responding...
I tried to tftp the running config from ASA to my laptop to analyse but got "No memory available" message...
So it seems like the "unzip" process of the pkg files used up memory... what is really the requirement of the mini Memory/RAM on ASA for hosting anyconnect Clients for 2 OS platform? Requirement on Cisco web site is kind of vague.
I am trying to configure my ASA 5505 security plus through ASDM to receive two blocks of outside IPs (each of which is on a different subnet and a different gateway ip) to translate to my internal server giving it public access.I have searched for days (and maybe incorrectly) but I am finally asking for the configuration of the ASA to support this.
View 1 Replies View RelatedWe have 2 IP blocks from my ISP. We have been using just one a /30 block with one IP address used on the outside interface of the device. The new block is a /29 range and I would need to use just two of those IP addresses. Here is the situation I am facing.A company we partnered with wants to set up a VPN, they will send us 2 Cisco 861s to put behind our ASA. Is it possible to assign these 861's with public IPs from the block that we are not currently using? (the /29 range)? I know that it might require an upgrade to the Security Plus.
View 7 Replies View RelatedI am trying to get up to speed on this topic as quickly as possible.
Here is my issue:
1) We are able to access the webiste
2) We are able to upload data packets
3) We allow the website to time out while we are uploading data packets
4) When we attempt to re-access the website the ip is blocked a) this includes pinging and trace
5) After an undertermined period of time the ip is unblocked and we are allowed to access it again.
The ASA 5505 router is the last forward facing stop before entering the VPN tunnel. We have tested by circumventing the ASA and we are unable to duplicate the disconnect. We have reviewed the config file and have not been able to identify what rule/settings could be affecting this.
when tracing port usage, the actions use 2 tcp ports and 1 udp port, the 2 tcp ports open and close by each transaction, when the ip block occures the 2 tcp ports are "dead" the udp port remains open (appearhently sending the remainder of the data packets)

This is 30mins after a restart. Seem like it gets worse and worse until i cant even connect to the ASDM.
I have Tried turning off loggin as well as some connection timeout commands.
I am looking at upgrading an HA pair of ASA5520's from 8.2(2) to 8.3(1), and am just wondering why the huge upgrade in memory is needed. How are Cisco justifying where the additional memory is going to? Are there supposed to be some massive improvements in performance?
