We recently got a Cisco DPC3825 DOCSIS 3.0 Gateway from Rogers since we're under their Rogers Extreme package and because the last gateway they gave people under that plan was garbage.
Now, when we got the gateway, I went ahead and forwarded all the ports I would need for my Xbox Live, I also went ahead and manually set up our primary and secondary DNS servers as google's (8.8.8.8 and 8.8.4.4) I did this on our last gateway as well (though only with a primary DNS) because Roger's DNS is very unreliable and google's proved to be much better.
I'm stating this becuase that's all the alterations made to the gateway.The internet, though very fast, is occasionally choppy. Occasionally, it will not slow down, but cut off all together. So let's say I'm buffering a video, all of a sudden the video will simply stop buffering and will only start doing so again if I reload the page or try to move specifically load a part of the video.This also translates to terribly unreliable connections when I'm playing online. The connection will fly from excellent to terribly erratically.
So now I'm wondering how can I deal with this. Do I have to disable the SPI firewall and blocking unknown internet requests? Is it the google DNSs I've set up that somehow don't work with this gateway?

Is it possible to install Content Security and Control (CSC) Modules on ASA 5505 ? Or only AIP SSC-5 Modules are the only modules that can be installed on ASA 5505s ?

Is there any option available in any of the Cisco ASA55xx series model to install both csc-ssm and aip-ssm ips modules ? If, so is it advisable to install both ? Is the throughput of ips module has any dependency with the asa chassis throughput ?

I am looking to add the IPS module to my ASA 5510's. I am contemplating only purchasing one module and placing it in the active ASA. I am willing to accept that in a failure scenario I will loose the IPS functionality until the primary ASA is recovered. I have not had a chance to talk to my SE to see if this is even possible. Has anyone attempted a deployment such as this? Will it work and is it supported?

understanding clear about new Cisco ASA 5515-x, 5525-x.I know that this device supports IPS which is included to this appliance without any additional modules.But can this box support IPS and content-filering (Cisco ASA CX or so..) in the same time.
The problem also in next. Can two ASA 5510 with diffrent modules (in one AIP-SSM and in other CSC-SSM) be in active/active failover design?

i two 5550 firewall set up for redundance purpose . in failover we define two different ip add one for primary and one for secondary .interface Ethernet0/0 nameif outside security-level 0 ip address xxxx.0.0.0.1 255.255.255.0 standby xxxx.0.0.2!interface Ethernet1/0 nameif inside security-level 100 ip address 10.0.0.12 255.255.255.0 standby 10.0.0.11.default gateway for host will be 10.0.0.12 (primary fw address) however in case of failover , the secondary fw will be up with ip address that was assigned for primary .in this case the secondary ip add 10.0.0.11 is actually nerver used? similarly do i need to have two public ip address for outside (one for primary and one for secondary ) ? or in case if primary fails the secondary comes onlie and take the ip of primary fw . hence i only need to purchase just one ip address.

we had just installed our ASA 5550 with IOS 8.0(2) a couple of week ago.
2 interfaces from each slot are being used ie 0/0 for Branch users comming via MPLS cloud , 0/1 for internal LAN users comming form Core Switch & 1/0 for Server farm LAN , 1/1 for Internet (outside)
the first 3 interface are considered inside with sec set at 100 while the 1/1 is outside with sec at 0.
Last night it suddenly started dropping all connections without any warning or any noticible log form the ASDM logging.
the connection drop would happen for 2 - 3 minutes and would work fine for the next 15 minutes or so..
after conencting the console , we found out that the IOS would suddelny go abrupt and show this display ...

I have looked in the books I have (Cisco ASA, PIX and FWSM; ASA 8.0) and googled a good bit but can't seem to find any specific mention of how to do NAT exemption with v8.4. It seems NAT exemption (NAT 0 access-list) was deprecated. Using ASDM, there's no corresponding menu item for this that is obvious.
We have public addresses inside the ASA and want to allow in/outbound connections using these IP's without NAT. The ASA is a 5550.

I need to understand if ASA 5550 ver 8.2(1) is comptible with IPv6, if not what is the upgrade path to make it IPv6 compatible. The requirement is dual stack of IPv4 and IPv6 should run in the same HA cluster and later will shift IPv6 completely.
The existing infrastructure is equipped with ASA with HA Active/Active mode. The command output for required details are attached here in txt mode.

I have Active Standby ASA5550 setup with VPN premium license. A few days back we had a requirement of SSL VPN connection for and we got a temporary from Cisco for same, this license expired and the ASA reverted to it's original license. 3 4 days after this we saw a sudden increase in CPU utilization (upto 90% + -5%) on the ASA during production hours but were not able to figure out the reason, in order to restore the services we failovered the firewall to secondary and everything worked fine. We were suspecting one of the following but there were no logs for any of this
1. The ASA hardware was haivng problem
2. Some client was doing a DoS attack to bring down the ASA (no logs for this as well).
We took a downtime to look further by failovering the ASA back to primary and it worked fine without any issues ruling out the 1st option. We also came across a licesing doc [URL]
Downgrading any license (for example, going from 10 contexts to 2 contexts).
# Note If a temporary license expires, and the permanent license is a downgrade, then you do not need to immediately reload the security appliance; the next time you reload, the permanent license is restored.
As per this doc, sooner or later a restart was required on the ASA. We restarted secondary ASA and everthing was fine but when we restarted the primary ASA by swtiching over to secondary some of the server (not all) in the DMZ stopped working (even ICMP unreachable) and only came back to normal when the primary ASA was restored and working fine (with failover).
The reboot was done by shuting down the physical link between the Core switch and ASA inside individually.
I am not sure what could be the issue that the servers in the DMZ wen unreachable.

In my Cisco ASA 5550, I need to set two different syslogs servers, and I need to send the system logs to the first one (only admins login/logout), and the traffic logs and all the rest (informational level) to the second one. Do you know if is it possible or not and, if yes, how to configure it?

I would like to work with two ASA's 5550 in HA (Acitve-Standby) like perimetral firewalls and also work with another ASA 5540 but like a SSL VPN Remote Access to end users.Which will be the best topology to this scenary?. Perhaps i need to put the ASA 5540 SSL VPN together with the ASA's in HA directly in a port.

I am using an ASA5550 for a complex secure network that has at least six "outside" networks. Each "outside" network is assigned to a specific port each set at level "0". I also have a DMZ, set to level "50". I am having difficulty with passing traffic from a host in the DMZ to all but one of the "outside" networks. Is there a limit to the number of "outside" interfaces? I will provide a redacted config file as soon as possible.

I have the following problem, right now we have an ASA 5550 connected to the client´s side. A reset is being received on the client´s side, but when we run the sniffers on both extremes of the network, we can see that the reset is not being sent by the server´s side.
We have narrowed it down to the 5550 ASA, but have found no bug that matches the description.
The characateristics of the reset packet are the following:
- It is the only packet with a TTL of 255.
- Both server and client have very different window sizes, and the reset packet even though has the server´s ip and port as source of the packet, it has the client´s window size.
- It has a correct ack number.
-Before the reset is received, there are a couple of retransmissions of the last packet sent.
- We´re handling a VPN tunnel between both servers.

I cannot logon with adsm anymore.when I run adsm, I type in my pw, and the screen keeps displaying "contacting the device". No timeout, just stays this way.I've updated the java version, no luck.I can connect with SSH with no problem. device = asa5550, 8.2(1) asdm 6.2(1) [code]
notice that there is no "with cookie-based authentication" here -- is this relevant?
Rebooting the device is not really an option.

We are having Cisco ASA 5550 appliance. from some days i am not able to access this ASA using ASDM. I am able to access ASA using SSH.[code]
At the same time standby firewall works perfectly fine with ASDM. I have tried by reloding the firewall, then it worked for 2 days & again stopped working.
