Remove Firewall Rule

hi friends how i can remove specific rule in firewall by c#

how i can remove specific rule in firewall by c#
Very carefully.
Which firewall? Don't you think if it were that easy to alter a firewall's settings that
it would be a pretty useless defense against hackers?
- Wayne
C# code has to be run way past the firewall. If the attacker is in a right and execution position to disable your firewall it already failed or never was a defense in the first place. Nearly all games developers took to adding apropirate exceptions for thier
games (so the user is not asked) to the Windows Firewall during installation.
Of course those codes have no effect if the user has any other firewall. The only truly reliable way to get an exception set is to try to make a connection (when your programm is NOT in fullscreen mode so it prevents the user from seeing it).

0x8007000e (E_OUTOFMEMORY) while adding a firewall rule using the windows firewall COM API

Hello,
Configuration: Windows Embedded 8 64-bit.
I'm using the Windows Firewall with Advanced Security COM API. The program uses the INetFwRules interface. Basically, I'm using the following code (Form the code sample available here : http://msdn.microsoft.com/en-us/library/windows/desktop/dd339604%28v=vs.85%29.aspx.)
I get the error when performing "hr = pFwRules->Add(pFwRule);".
We can also encounter the problem when removing a rule (using pFwRules->Remove(ruleName);)
HRESULT hrComInit = S_OK;
HRESULT hr = S_OK;

hr = pFwRules->Add(pFwRule);
if (FAILED(hr))
printf("Firewall Rule Add failed: 0x%08lx\n", hr);
goto Cleanup;
This works pretty well but, sometimes, at system startup, adding a rule ends up with the error 0x8007000e (E_OUTOFMEMORY) ! At startup, the system is always loaded cause several applications starts at the same time. But nothing abnormal. This is quite a random
issue.
According MSDN documentation, this error indicates that the system "failed to allocate the necessary memory".
I'm not convinced that we ran out of memory.
Has someone experienced such an issue? How to avoid this?
Thank you in advance.

Does Windows 8 desktop have the same issue? Are you building a custom WE8S image, or are you using a full WE8S image? The reason I ask is to make sure you have the modules in the image to support the operation.
Is Windows Embedded 8.1 industry an option?

SA540 Firewall Rules Fail when Optional Port Configured to Failover

Today, I configured a client's SA540 for failover. The primary WAN port is FIOS with a static IP address. The optional port is Road Runner cable with a static IP address. The failover tested successfully. However, now the SA540 cannot be accessed on its internal IP address (https://192.168.1.1) and none of the firewall rules work any longer. There are several rules but to name two; remote desktop port forwarding to an internal server, and HTTPS to another internal server. Both rules use IP addresses different than the SA540's WAN IP address. Additional external IP addresses were configured previously and assigned and they worked up to the point were the failover was configured.
Now here is the strange part. If the optional port cable is removed from the port, everything returns to normal, but plug it back in and problems. I even tried disabling failover in the SA540's configuration and it made no difference unless the cable was unplugged.
As you might imagine the client is upset about this. Anyone have any ideas?
The firmware is 2.1.18.
Tony
PS. About an hour after I posted this, I tried moving the remote desktop external connection from one of the additional IP addresses configured in the SA540 to the dedicated WAN address and remote desktop sessions were then forwarded into the correct server. Apparently, the additional IP addresses are not working with the two ISP failover configured, or at least it doesn't work in my configuration. Any help on this would be much appreciated. The additional IP addresses are configured in the same subnet as the dedicated (primary) WAN port. Again, this worked until failover with another ISP was configured.

This issue has been resolved. After much testing and discussions with the great guys at Cisco TAC, we determined that Verizon FIOS is doing something on their routers to defeat use of IP aliasing. If you have FIOS and you must have more than one IP address and expect to create an IP alias to direct traffic in a 1 to 1 NAT to a node on your network, FIOS doesn’t work. Contact with Verizon technical support is no help. They are oblivious to the problem and don’t want to be bothered.

SA520W - IPv4 Firewall Rule not visible

Hello,
We have a cisco SA520W Security Appliance Model with several IPv4 firewall rules configured and we would like to remove one of the rules.
The fact is as that this rule is not visible from the Security Appliance Configuration Utility, although it can be seen on the configuration backup file, it cannot be deleted…
Any idea how to delete this rule avoiding to revert to factory default setting will be appreciated.
Best regards,
Nicolas MASSOT

Is it one of the built in default rules or is it a rule that was created then deleted from the GUI? Can you paste the section of the config file with the ACL?

Add firewall rule with custom environment variable in program path

Hi,
We want to create a firewall rule for a program which is placed in folder which changes sometimes. I know you can add a firewall with the ProgramFiles environment variable like this:
netsh advfirewall firewall add rule name="Test Firewall rule" dir=in program="%%ProgramFiles%%\Test\Test.exe" action=allow security=notrequired
The environment variable ProgramFiles isn't expanded and if the Program Files folder is different on a system the rule still works.
We try to use this with a custom environment variable which we set a system environment variable with this command:
SETX SomeFolder "D:\Some Folder\Apr 2015" /M
If we use the command below to add the firewall rule in a batch file the environment variable SomeFolder is expanded correctly and the program path is added as a static path.
netsh advfirewall firewall add rule name="Some Firewall Rule" dir=in program="%SomeFolder%\AFile.exe" action=allow security=notrequired
Because the folder changes sometimes we want to change the environment variable SomeFolder and not remove the old firewall rule and create a new one. We want to add the environment variable SomeFolder to the program path as a (dynamic) environment variable
and not as the expanded path at the moment when the rule is added. If we use this command:
netsh advfirewall firewall add rule name="Some Firewall Rule" dir=in program="%%SomeFolder%%\AFile.exe" action=allow security=notrequired
We get the error:
          Windows Firewall with Advanced Security
          An error occurred while adding the rule.
          Error: The parameter is incorrect
          Status: The application name could not be resolved
          OK
Why can't we use %%SOMEFOLDER%% like we can use %%PROGRAMFILES%%? The same error is shown when we try to add the firewall rule through the management console 'Windows Firewall with Advanced Security'
W. Spu

Hi,
Based on my plenty of test with this problem, it seems like there is no better method to achieve your requirement. To add new policy to firewall, it would be better using general cmdlet. The path parameter like %%SomeFolder%% do have problem in add firewall
policy cmdlet.

Modifying Firewall Rules On a Unbooted System

If my subject wasn't clear, here is what I'm asking.
I want to know how I can "clear out", meaning restore to factory defaults, the firewall settings on an OS X Server installation. But not on the boot drive. My server has two drives. And as a last resort, I'd like to know how I can, while booted off it's backup drive, access the main boot drive and revert the firewall rules. That way I can boot off the main drive again, and have full access to the machine, where I can then go in and set it up again.
So I guess I need to know where on the filesystem these rules are stored. And if there is anything I have to do to flush old rules out. Again let me reiterate, I'm not talking about on a running OS X System, I'm talking about doing this to a secondary drive that isn't the boot drive.
Hopefully I won't need this information but just in case, best to have it on hand.
Thanks

If I understand you correctly...
On Leopard, it seems the firewall is started based on the presence of this file:
/etc/ipfilter/ipfwstate-on
If you remove it, the firewall should not be enabled allowing you to login and change the settings.

How to reload firewall rules from command line on firewall ?

Hi all,
I am trying to create script that controls firewall on server. OS version is OS X Server 10.5.6.
Part of firewall rules is created using firewall admin tools, part of Server Admin Tools. My first question is where are those rules stored permanently ? As far as I understood it should be set of ipfw rules but they are not stored in /etc/ipfilter/ipfw.conf.
Idea of script is this:
I have set of rules that should be controlled by Server Admin Tools.
Also, I have some dynamic rules.
Whenever some change occurs, I created script that does following:
/sbin/ipfw -f flush - to flush all existing rules
/sbin/serveradmin stop ipfilter - to stop existing firewall
/sbin/serveradmin start ipfilter - to restart firewall and reload permanent rules
Add my set of rules...
After flushing all rules and issuing stop and start ipfilter none of rules set through Server Admin Tools are not reloaded. So how should I reload them ? How to save them permanently in the first place ?
Please note that I do not have access to server (for security reasons). I am developing script on my Mac, sending to client and he tests it. So I cannot do a lot of testing.
Thank you in advance.
Best regards,
Dusan

Can't add a new Firewall Rule

I have a very curious issue: I cannot add any new firewall rules at all! Clicking on the New Button does nothing and on the console I get
System Preferences[487] * -[NSCFString objectForKey:]: selector not recognized [self = 0x3f11b0]
I have flushed the firewall with ipfw, deleted the plist file, repaired permissions but the problem ist still there. Any suggestions? (apart from reinstallation)
Adding Firewall Rules through ipfw works...

Whenever I use ipfw I lose the ability to use System Preferences. At first I thought that it compared kernel memory with the plist file and if it found a difference, assumed another firewall was running and disabled itself. But I also deleted the plist file (assuming it would build one from kmem) but that didn't work. Right now I assume there's another file somewhere. It wouldn't make any sense to keep another table in kmem. The weird part is that rules can be the same, but different sequence numbers will cause this problem. There weren't sequence numbers in the plist file, so there's probably another file somewhere.
I think your error is from the missing plist file. A reboot should clear it up.

How to remove the rule or class function in CS5

i need to know how to remove the rule or class function in CS5 at the bottom of the screen there are two options for formating HTML and Css when i click the HTML it only allows me to change the bold or italics or link something but when i click CSS it allows me to format how i want the paragraph aligned and the text size and font when i click on lets say changing the font size a box comes up asking me to name a rule so it applies it to everything else i type i want to know how to stop tht like edit everything on my own and if i use CS5 here will it be compatible with CS4 or CS3 at my skool plzz help ive been frustrated with this

If I use CS5 here will it be compatible with CS4 or CS3 at my skool plzz help ive been frustrated with this
Code is code. It doesn't matter which product you use.
i need to know how to remove the rule or class function in CS5
You can't. DW encourages you to use good coding methods, which means using CSS classes and to keep content (HTML) separate from styles (CSS). For example, if you change font-size on p tags like so:
p {font-size: 38px}
Every paragraph will have 38px sized text.
If you want to apply a special style to just a portion of your text, you must define a CSS class name like so:
.foo {
font-size: 38px;
color: red;
HTML:
<p>This is normal paragraph text <span class="foo"> And this is very big and red.</span></p>
This is normal paragraph text And this is very big and red.

Appending Firewall Rules to vShield Edge with PowerCLI Script

Hi,
I have a script which enables us to upload 4k worth of firewall rules, but every time it executes, all existing rules are over written.
Is this something to do with the API or just a scripting issue - if so, can anyone suggest how to append on to the existing set?
Update:
So obviously the following line seems to create a new instance of the firewall:
$fwService = New-Object vmware.vimautomation.cloud.views.firewallservice
Because the next 3 lines after are setting the main firewall parameters again - something you wouldn't need to do if we were just adding new rules to the existing firewall.
$fwService.DefaultAction = "drop"
$fwService.LogDefaultAction = $false
$fwService.IsEnabled = $true
Is there a way to use a PowerShell command such as add-member rather than new-object?

SA 540 INBOUND FIREWALL RULES NOT WORKING

Hi all,
I am having trouble configuring the firewall for the SA 540.
client 1 (160.222.46.154) ----- switch ------ sa 540 ------ cisco 887 W ------ client 2 (50.0.0.10).
client 1 can ping client 2, however client 2 cannot ping client 1. The default outbound policy (allow all) is set on the sa 540, and I have tried configuring a blanket ipv4 rule on the sa 540 to allow 'all' to 'any' (for all services) related to traffic from the WAN to LAN, and visa versa. The output from the logs are as follows:
Fri Jan 7 13:43:04 2000(GMT +1000) WARN FIREWALL 50.0.0.10 160.222.46.154 [firewall] LOG_PACKET[DROP] IN=WAN OUT=WAN SRC=50.0.0.10 DST=160.222.46.154 PROTO=ICMP TYPE=8 CODE=0

Component: KERNEL
Basically any connection identified as coming in from the WAN (i.e. IN=WAN) is dropped. I set up a new vlan on the cisco 887 W, in the 160.222.46.x address space, and connected a spare port directly to the sa 540 and had no problem testing connectivity to any device via ping. Obviously the zone communication is LAN to LAN and firewall treats the traffice differently.
I assumed that creating an all encompassing rule to allow all trafiic, for all services, between the LAN and WAN (in both directions) would be equivalent to placing the appliance in PASS THROUGH mode? There is no securtiy set on the 887 W or the switch.
Also is anybody could explain what 'SELF' means in the conttext IN=SELF or OUT=SELF it would be much appreciated. Firmware is latest.
Thank you.
Regards
Marc

On closer analysis and with some help from Experts Exchange it did seem non sensical to have both the IN and OUT as the WAN interface, but I had literally exhausted every avenue possible bar 1- changing the routing mode to CLASSIC and configuring a static route (which was at a higher administrative level than my RIP advertised routes) and took preferece when forwarding the packets.
Now the SA540 firewall rules work as I would expect and I can route between all zones. To summise it appears as if the Double NAT from the router (887W) and then the SA540 was the issue, and the innability to configure any workaround in the interface of the SA54O firewall rules.
It really makes you appreciate the power of the command line and the full scope of CIsco's command line options. Does anybody know if (and how) it would be possible to configure Double NAT on the SA540?
Regards
Marc

ISE 1.1.1 firewall rules distributed deployment

My question is in reference to the following link:
http://www.cisco.com/en/US/docs/security/ise/1.1.1/installation_guide/ise_app_e-ports.html
Basically I am struggling in some areas to work out my firewall rules for a distributed deployment. The referenced documentation is not entirely clear in my opinion. In some instances it is easy to work out what ports need to be opened eg Admin node TCP 22,80,443 for management from administrator hosts/ranges. In other instances it difficult to work out eg TCP 1521 Database listener and AQ is this for ISE nodes only or for access devices aswell
My question is whether there is a better document that details these requirements. What rules are meant to be ISE node - ISE node communications and which rules are for access device - ISE, or ISE - access device. One of the rules I am pretty confused about is the PSN CoA ports. SHould the rule be WLC - PSN on 1700 and 3799 or is it the otherway round or unidirectional?
I am pretty sure that the ports are meant to be ISE-ISE in most instances barring the PSN for Radius and CoA.

Try this for size.
In answer to the specific CoA question, I see no need for the WLC to send CoA to PSN, so just PSN to WLC as far as I can see.
You might be able to cut this list down, and you might have to add to it for any specific requirements.
From PSN to AD (potentially all AD nodes):
TCP 389, 3268, 445, 88, 464
UDP 389, 3268
From PSN to Monitoring nodes:
TCP 443
UDP 20514
PSN to Admin Nodes (2Way):
TCP 443, 1521
ICMP echo and reply (heartbeat)
WLC to PSN:
TCP 443, 8443, 80, 8080
UDP 1645, 1646, 1812, 1813, 1700, 3799, 161, 162, 9993, 67
PSN to other PSN’s (2 way)
UDP 30514, 45588, 45990
Endpoint (Laptop) to PSN (Guest laptops just need to get to external PSN’s, internal users just to internal PSN’s)
TCP 8443, 8905
UDP 8905
Admin/Sponsor to all ISE nodes:
TCP 22, 80, 443, 8080, 8443
UDP 161
PSN access to DNS servers:
TCP/UDP 53
PSN access to NTP servers:
UDP 123

[Solved] Windows Firewall rule that allows Windows Update

Can anyone kindly give me a Windows Firewall rule that allows Windows Update? Assume I'm running MMC's "Windows Firewall with Advanced Security" snap-in as Administrator. Note that a "solution" that takes down the outbound firewall is
not acceptable.
Thank You.
===== Solution =====
Suppose that, as the default, you've set the outbound firewall to block (see
To close the outbound firewall, below). In order for Windows Update to check whether an update is available and then to download the update files, you first need an outbound firewall
allow-rule that allows the Windows Update service to pass through the outbound firewall.
Prerequisite: Knowledge of the Microsoft Management Console (MMC) and its "Windows Firewall with Advanced Security" plug-in.
What you will do: You will use the "Windows Firewall with Advanced Security" MMC plug-in to create an outbound firewall rule that
allows '%SystemRoot%\System32\svchost.exe' (the generic service driver) to pass through the outbound firewall on behalf of 'wuauserv' (the name of the specific service that performs the update).
Warning: If you don't know what I'm writing about, get help.
Name: Allow Windows Update (...or any name you prefer - it doesn't matter)
Group:
Profile: Public
Enabled: Yes
Action: Allow
Program: %SystemRoot%\System32\svchost.exe
Local Address: Any
Remote Address: Any
Protocol: Any
Local Port: Any
Remote Port: Any
Allowed Computers: Any
Status: OK
Service: wuauserv
Rule Source: Local Setting
Interface Type: All interface types
Excepted Computers: None
Description:
To open the outbound firewall:
More accurate wording would be
Outbound connections are allowed unless explicitly blocked by a rule.
If you look at the standard rules you will find no block-rules. That means that nothing is blocked, everything is allowed, and the outbound firewall is wide open.
To close the outbound firewall:
More accurate wording would be
Outbound connections are blocked unless explicitly allowed by a rule.
If you look at the standard rules you will find only allow-rules that have been crafted to allow the vital Windows connections to pass through the outbound firewall. To an informed observer it's obvious that the firewall engineers crafted these
allow-rules so that users who closed the outbound firewall wouldn't have to write them. But the firewall engineers left out Windows Update.

Hi mark,
Thanks for sharing, it will help other users who have similar issue.

Where is the firewall rules file??

I had to tweak a bunch of firewall rules following this latest Apple security update (it broke my mail services). In the log (G5 Xserve running 10.4.11), it now says
"mail servermgrd_ipfilter:ipfw config:Error:Failure code returned by ipfw command: 64, message: Line 22: recv,xmit via require interface name or address"
but I only have 19 rules in my "Active rules". Where would this bad "line 22" be located?
Mike

I'm not sure about 1.5, but normally there isn't one. The defaults are just used unless there is one.

DLINK 2750B - Entering Custom Firewall Rules

I am having difficulty entering these rules below. I seem to be able to add the "allow" but dont see how to add the blocking. How does one block a a port to an IP or IP range? ALLOW TCP/UDP IN/OUT to 208.67.222.222 or 208.67.220.220 on Port 53 and below it BLOCK TCP/UDP IN/OUT all IP addresses on Port 53 Forcing DNS so it can not be circumvented to OpenDNS parent filter, I dont care if its not supported, I just need to know if it can be done. Any ASSISTANCE, specifically with this firewall setting on this device, in performing this task with this modem is greatly appreciated, color commentary is not. Thank you very much!

In this case, you will want to make sure the DNS Rule for allowing the DNS traffic is allowed with priority over the deny policy. Make your allow policy by specifying TCP and UDP as allowed, Port 53, to both of OpenDNS's servers. Two identical rules, less the IPs will need to be created in many cases.
In most cases, you can usually set an "All IPs" range by leaving the IP address set to 0.0.0.0 with Port 53 and TCP/UDP set. Note that because DNS can work over either TCP or UDP depending on the server, you must filter both protocols. It is best to use "REJECT" in order to kill off DNS requests, as "DROP" will cause latency.
I do not know how the D-Link will treat creating rules in this fashion, let us know what your results are. If your question involves where the Deny/Reject/Drop options are for the firewall rules, then please provide a screenshot of what you see to help us out.
