I've been asked to turn on logging for code ASA-6-302014.  According to Cisco it's the Teardown TCP connection.
I have logging enabled and have set notifications  for syslog ID 302014.  I can't seem to get ASA-6-302014 to show in my log files, but I get ASA-5-302014.  Is this the same thing?

Our ASA is a 5520 8.2(1)

MSPs: Endpoint security isn’t enough to prevent ransomware.
As the impact and severity of crypto ransomware attacks has grown, Webroot has fought back, not just by building a next-gen endpoint solution capable of preventing ransomware attacks but also by being a thought leader.

In Palo Alto Networks there is a test sec policy command that will let me know whether the traffic from source A to dest B for port C will pass or be denied. i.e. test sec policy to ALLOW (or DENY). Is there a similar function within VMWare NSX?
Hello - we upgraded from a 5510 ASA to a 5516 recently.  On our old 5510, the home page of the ASA would present the ASDM tool.  the 5516 does not do this.  After spending an hour reading the Getting Started guide and online, I find lots of information about how the ASDM works - but hardly any help on how to actually launch the tool.  Need some help from the experts.  thanks
Hi Experts,

I am currently looking for a managed, software or hardware firewall option for a business grade internet connection and WAN. I don't know much about firewalls beyond what is available on your average home computer and I am a little unsure where to start.

Please can you tell me your thoughts on what is best for a business.

If I were to purchase a unit, is this something that can easily be learned, administered and managed in house or is this something that requires a real specialist?
Should I use a software, hardware firewall, or a managed offering?
What sort of costs can I expect for a reasonable solution?
What should I look out for?

Any expert advise would be most appreciated.

Thank you

Is there a way to block an entire folder including the .exe everything inside a folder from connecting to the internet? If Windows 10's Firewall can't is there another Firewall that can?
I have been seeing quite a bit of traffic attempts from a specific ip address to access the above described firewall
how can I block this specific ip address without just blocking all?
Hi, we are preparing the rules for Zone-based Policy Firewall on Router c3925, however we need to confirm which traffic usually pass through a router, so that the rule will not block/allow any useful/bad traffic. So can we have a method to see it?

Is there a way other than: "show ip cache flow", "sh ip traffic" ?  

Many thanks in advance,
Hi, we are having Router Cisco 3925 between LAN and WAN, however it seems like the money is required for AnyConnect VPN on Cisco 3925. We found that pfSense (Free) can be deployed to serve VPN connections however we need to understand its pros and cons.
-So can anyone explain please?
-Should we deploy it or purchase license for AnyConnect?
-Do you know any free Cisco VPN solution that we can configure inside our C3925?

Our priority is:
- Compatible with current environment with minimum impacts to about 400 users
- Easy to configure and troubleshoot
- Price  

Many thanks in advance,
I have a new customer the VPN going straight to the customer was working fine with Comcast crappy router, I install a pfsense and created a rule under nat for VPN, setup server with a static IP etc. somehow this does not work. any help greatly appreciated

HI I am kind of new to this of sense firewall, I have the latest release, my question is about the subnetting for I have to use /30 if I'm not mistaking. also if I'm setting up a VPN server inside the network were do I open ports for this. I look into the nat and configure some things there but I can't be sure.
what is the best to have the selection criteria for Firewall and Endpoint security  in the TC level . most  of the  firewall and the end point security has the similar common features . so that very difficult to select the over another  . some are saying we are in the top 3 in the that report , some are saying  we have the gateway level syn .  with the end point , like wise

please give me the best approach on this . we don't want to have the most expensive product

We have a Windows Server 2008 R2 configured as a NAT Server. Currently we have limited bandwidth, so I would like to monitor usage per user. Is it possible to monitor usage via Windows somehow? If not can anyone advise a freeware solution?

Best Regards,

Hello Experts,


The system includes

OS: Win2012R2

3G router (VPN SIM Card)
Interface ppp0 IP:
Interface usb0 IP:
OS: ARM Linux

Client PC


3 of them connect by

Server <---> 3G router <----> PC Client


The 3G Router is basic linux with nothing but iptables command. I tried several command option but did not work so far.

Such as,  
/mnt/nand1-1/ap/iptables -t nat -A PREROUTING -p tcp -i ppp0 --dport 21 -j DNAT --to-destination

PS. PC client can Ping 3g Router IP: but cannot Ping
Will you have any ideas?
Thank you.
I am going to setup a new PFSense firewall. There are few pieces of equipment on the network that I don't want to have to pay for public facing static IP's for, but I would like to open ports up so they are publicly available to the maintenance people when they are offsite. How do I go about containing those IP's so they can only see out to the internet and not internal to the network in case those pieces of equipment were to be compromise?
I am configuring the NSG for inbound traffic for a Virtual Machine hosted in Azure.
The inbound rule looks as follows:

The advisor is alerting that connetions say any / any
I need to leave the incoming as any because the users of the site may come from anywhere, but the destination should only be the VM particular website.
How should I configure the destination IP ?

currently looks like this:

I am not sure what to enter in the source port/range?  The internal IP of the server, the external IP of the IP of the firewall where the DNS points at?
"...some settings are managed by your system administrator"
I did a gpresult and can't find any GPO that is related to firewall.

I uninstalled Symantec Endpoint Protection and since then can't turn it on. Downloaded their app uninstaller to make sure it was fully uninstalled but it made no difference. Any ideas guys?
I would like my router to forward port Pxyz to computer, say.  I know how to do that with my router.  What' hanging me up is: How do I use windows firewall and an incoming rule to send Pxyz to , say 3389 for RDP on my server that is sitting at

If I use plain old generic 3389 and just enable that, sure it works great.  But I really want to specify a pseudo-random port number for RDP, but I really dislike the registry hack approach.  That just seems super inelegant and forced, to me, when I know port forwarding and routing are available!

We accidentally clicked on "Restore Default" in Windows 10 firewall screen and now internet extremely slow and most times it doesn't connect.  When we check the inbound it had many option uncheck when prior the restore were check.  Unfortunate we don't know which should be checked or not.  Any EE can help us set the inbound to permit normal internet usage.  Note, prior placing the questions we thought it was the AV apps and we uninstalled them and installed again but didn't work.

Pleases advice.
Hello All;

I am going to use the following script to add to the Windows Firewall, a list of IP Addresses.

netsh advfirewall firewall set rule name="IP Block" dir=in interface=any action=block new remoteip=<IP_Address>/32,<IP_Address>/32,<IP_Address>/32,<IP_Address>/32

Open in new window

2 Questions.
How do you UPDATE an existing rule?
The above script will update the existing RULE, however. It will overwrite all the IP Entries.
I need to add to that list.

I test the script to make sure it would work, and I added my other computer to it.
Well, it works and now my other computer cannot access this computer.
I deleted the entry, and still cannot access this computer.
I cut off the Windows Firewall for Domain, and the computer was then able to access this system.

So, HOW can I remove an entry, if a person contacts me, that is an innocent bystander, that was not a part of the hack attempt, and needs the IP removed. I would HATE to have to reboot the server every time I get a request to remove an IP Address.

(I believe the mistake I made, was "Deleting" the rule, and I should have "Disabled" the rules.
That is what I get from reading the site.
That only Disabled Rules are not monitored as Active.
So, it seems the ones I deleted, and still showing as Active)
I checked in the Registry, and there is nothing there.
So, I am unsure where these are located at.

Inbound (ONE rule with 2 entries)
Windows Firewall Inbound IP Deny RuleFirewall (THREE Hack Attempt Rules) These cannot be removed. There is NO option to remove them.

Hello All;

OK, as the subject states. We are wanting/needing to block IP addresses.
I do not currently have a professional industry standard hardware firewall at the moment.
So, we are going to rely on Windows Firewall or Other, software based Firewall.

Whichever route that we take.
We will need to have access to the file that the IP Addresses are stored at.
Rather is it through

Windows Server
     Windows Firewall and Advance Security
          Inbound Rules
OR, through

IIS - Internet Information Services
                   IP Address and Domain Restrictions

I am thinking that using the Windows Firewall and Advance Security,
Would be the better of the two to use.

If either one of these are the ones, and I would prefer to stick with either one of these.
(preferably the Window Firewall)
How would I access the file where the IP Addresses are stored at?
I am writing a application that grabs IP Addresses of potential hackers on our mail server.
The script is fully functional already, except for blocking said IP Address from access the system altogether.

Any ideas suggestions, anything.
Thank You
Hi All,

Had anyone done firmware upgrade for pfsense from 2.2.6 to 2.3.3? is it stable? what instructions you followed for the upgrade?

We have API comms with our vendor.

In what way(s) do an API firewall help?
