Dec 28, 2012
I 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 have this problem with the Polycom Video Conferencing (HDX 7000) While we can initiate a video call to other locations, we can not receive a video call from other locations. Whenever there is a incoming call, the polycom is ringing fine. but once we answer the call, the call will be disconnected. Our access rules are listed below, 203.125.99.99 is our public IP for example.

We are trying to get a video conference system (POLYCOM) up running. Thrue a Cisco 1812 router with Firewall feature set.
I Have heard in the past that there should be issues with Polycom and Cisco, but have actually never seen it.I can establish a video call from inside the 1812 to outside.
But when I try from outside to the public ip adress there is nattet to, then it reach the video system and die straight after, so there is never any video session set up.
I have tried to remove everything regarding firewall feature and passing true, so the only thing the 1812 should do is NAT. And still the same.
I can not see anything in the log on the router from the ACL's where I permittet everything, other then it connect on the port TCP 1720, as it should. This is the software I'm running on the router:
Cisco IOS Software, C181X Software (C181X-ADVIPSERVICESK9-M), Version 12.4(15)T3, RELEASE SOFTWARE (fc1)
When I search Google, it look like there is a lot issues with Cisco and Polycom, but I have not found any concret solution. Other then I should use a ADSL line with a public IP address. As we probably is going to do.

I am trying to set up a Cisco ASA 5510 running 8.2 to allow a connection to a Polycom camera that sits behind it. What I want to do is forward multiple ports to allow a connection from an outside office. The polycom camera uses the following ports:
1720 tcp
3230-3235 tcp
3230-3253 udp
I got these port numbers from the Polycom web site. So what I did was create a service object as follows:
object-group service All-Polycom-ports
service-object tcp range 3230 3235
service-object tcp eq h323
service-object udp range 3230 3253 My question is how can I use this service object in a static (inside,outside)
command so that I don't have to create multiple commands for the port forwarding. Is this even possible or do I have to sit down and write out around 30 seperate commands to do this. I've been searching the web and it seems a lot of people want to do this but so far I haven't found an answer.

Running FWSM Firewall Version 3.1(4)
The problem is that calls originating from the outside of the firewall to the inside will ring but you cannot answer. The internal video conference server is a Polycom HDX 7000. There are ANY/ANY rules to/from this server and the default application inspection policy is set for h323/ras/h225 as follows:

i need to upgrade ASA 5540 from 7.1 to 8.4 for secure connect feature of Cisco Jabber Configuration. Support forum guides that, i need to follow upgrade path from 7.1 --> 7.2 --> 8.0 --> 8.2 -->8.4 and also do a memory upgrade from 1GB to 2GB.
[URL]
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?

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-

I 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?

Just 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?

there was remote FTP - users behind ASA5540 can connect to it.
Now, with this ftp there is SSL/TLS encryption added and users behind this ASA can't connect to this FTPS.
It this possible for users behind ASA to connect to FTPSs?

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.
