View 1 RepliesI am encountering some problems setting up my new polycom hdx 8000 behind ASA 5540?I have opened reuired ports through the firewall ( incoming and outgoing). I have enabled inspection h323 on ASA and enabled the option NAT is 323 compatible on Polycom.
3230-3243 tcp
h323 tcp
h323 udp
3230-3285 udp
Here is the problem.I get connected to the call but I cannot the remote site cannot see and hear me.But I can see and hear them.
I am currently migrating a netscreen firewall to a asa 5515 version 8.6 The issue is setting up the management connectivity.
basically the management IP of the cisco asa is not advertised. But, we want to route a management IP through the management interface to interface Gi0/2.
so IP of management interface is say - 216.10.100.10. and the IP of the inside interface is say - 198.1.1.10/24 on our router we have a static route sending 198.1.1.0/24 to next hop of 216.10.100.10 (management interface of cisco asa).
On the Cisco ASA can I send the traffic to the inside interface and manage the firewall via ssh that way?
I'm trying to install an ASA 5510 transparent firewall using ASA version 8.4(3)9 but I don't understand how traffic will ever pass through my firewall if both interfaces are on the same sub net(V lan) as the host and it's default gateway? The reason I'm doing this is were installing UAG (or Direct Access) and the UAG appliance need to have public IP's but still be behind a firewall (see attached diagram).
Looking at the documentation (which all seems to be for 5505's running 8.2) it almost seems like i need to have the transparent firewall 'in-line' to the ISP router?, but this router services another IP address range on another v lan for other (routed) firewalls (not shown on diagram) so putting it 'in-line' is not possible. Surely this can't be the case can it? If not how is it supposed to be cabled up and configured so packets go through the firewall?
provide me with the important links which can show me how to do the software upgrade for my ASA 5520 ver 7.0(1) to ver 8.4 ? as well as the ASDM

I need to use this feature for only three or maximum four users in company then would i really need to do memory upgrade? or can i go with 1GB memory?also how i can get the prices of part number "ASA5540-MEM-2GB=" at cisco.com?
ASA-ISB-HQ# sh version
Cisco Adaptive Security Appliance Software Version 7.1(2)
Device Manager Version 5.1(2)
[Code].....
ASA5540# sh run nat-control
no nat-control
this means higher security can talk to lower security without NAT rules
Question 1) - if I want higher security zone to to talk to lower security with NAT rules. I would use statements like below. Am I correct?
nat (dmz) 1 0.0.0.0 0.0.0.0
nat (inside) 1 0.0.0.0 0.0.0.0
global (dmz) 1 interface
global (inside) 1 interface
Is this correct? So in this case I am kindly of like overriding the no nat-control statement ...right?
Question 2) - Now I have no nat-control enabled. Would the below statements (nat 0) be of any use for NAT exemption??
nat (dmz) 0 access-list dmz-nonat
nat (inside) 0 access-list dbase-nonat
And do I have to have a global statement for NAT 0 ...like below?
global (dmz) 0 access-list dmz-nonat
global (apps) 0 access-list dbase-

View 2 Replies View RelatedI have a remote site customer with a Cisco ASA 5540 running SSLVPN (Anyconnect)(8.03). It currently only serves about 450 SSLVPN clients. Since last friday, they've seen the CPU utilization go up to high 90% while only serving 400+ remote users. I saw some high cpu utilization bugs, but none looked to be relevant. How I can find the root cause of the CPU high utilization?
View 2 Replies View RelatedJust upped our external ASA-5540 pair to 8.4(1), and now one of our nat's is busted.
Here's the lowdown:
Our public IP for our IronPorts ends in .167. That IP is natted to a VIP on our ACE, which load balances to the IronPorts.
The outside interface of the ASA uses .162, which has been the pat for all outbound traffic for a few years... except for the subnet that houses the IronPorts. Due to reverse lookup, that subnet uses the .167 IP address for all outbound traffic.
After the code upgrade, the nat won't work. No email sent or received. Nothing but Deny's on the ASA with flags reading either "SYN" or "RST". IE: Apr 27 12:56:11 10.22.151.41 local5.crit %ASA-2-106001: Inbound TCP connection denied from 69.25.174.17/36917 to 207.236.211.167/25 flags SYN on interface outside
If I return the subnet pat back to the outside interface, then inbound traffic works fine, though reverse lookup fails and anyone running a reasonable spam filter won't send to us.
I have two Cisco ASA 5540, these ASA running ver 7.2. and used mainly as VPN gateways.My question is simple, Apart from the extra AnyConnect client functionality and the higher encryption, is there any specific security benefits (related to the VPN use) for upgrading to ver. 8.x ?

I have 2 ASA 5540's that I want to run in HA A/F. The active ASA has an IPS module running. I no longer need this and would rather remove it than purchase another module for the spare. What is the process to do this safely? After removal will the HA wizard recognize that the module was removed or do I have to update the software?

I got the information from this webpage: [URL]
rommon #1> ADDRESS=10.132.44.177 <---- Which IP address? the one that I got on my firewall?
Q1. I would like to confirm like how many total of contexts do I have by default when I purchase the ASA 5540 ? are they two contexts aside from the admin context or two contexts including the admin context?
Q2. can I configure the default box with High Availability using the default contexts?
Does ASA 5540 support BGP routing protocol to be configured on it??
I'm talking about the latest versions.
I have an ASA 5540 , how can i block softwares like TeamViewer , VPN Adapters like Hamachi and all. Also , I have tried URL Blocking but i suppose ASA supports only HTTP url block and not HTTPS.

I am in the process of rebuilding our ASA 5540 pair. We are currently on 8.2 code with this set of firewalls and I was going to upgrade it to 8.4 being I have a couple of other firewalls running this code currently and am familiar with it. That said, I saw that the 9.x code is out there now. Are there any major advantages or caveats with the 9.0 code? I plan to use this firewall with SSL VPN and RSA Secure ID integration for the next 2-3 years at least. Any quick pointers on these two code versions and on upgrading to 9 or staying with 8.4 line.

I'm having a throughput problem with a new ASA 5540 running version 8.2 (1). When trying to access a database server using tcp port 1521 (sqlnet) it is about 10 to 20 times slower than when the database is not behind the firewall. We've been running the same software on a database behind an ASA 5520 running version 8.0 (3) with no problems for years. When I check the cpu usage on the 5540 at the ASDM home page, it is rarely above 20% and never above 30% while this is being tested. I tried testing ftp throughput over the same interface and it was normal with ~320 Mbps average rate transferring a 500 MB file.

We have a VPN established between the above devices (I don't have more info on the Juniper as it's a client site) The Juniper initiates the VPN and all is well, tunnel is up all ok but approx every 45 minutes the VPN drops.
the tunnel parameters are set to keep it alive for 8 hours but that doesn't work.
We have an ASA-5540 (8.4(1)) The inside interface faces a few multicast receivers. The outside interface faces the multicast source.All of the ASA multicast documents I've download describe very simple network designs, such as a single segment on the ASA inside.Our PC hosts that will be multicast receivers are a couple router hops away from the ASA inside interface. I'm not sure what the best way is to configure multicast on the ASA.Should I configure the ASA with PIM routing and a static RP address (plus the ACL to allow the multicast source traffic in) since the receiver hosts are a couple hops away? I think I understand the IGMP joins are for a local PIM router, so configuring as a Stub Multicast router wouldn't work? The two Cisco routers between the host and the inside ASA interface already have PIM, a static RP address, and IP PIM Spare-Mode configured.
