Deleting a firewall rule.

A firewall rule is causing some problems for me, rule 12190, how do I delete this rule from the firewall?
It looks like I have to use ipfw from the command line but I am not sure of the syntax.
Thanks for your help.

SA520 Firewall Rule cannot block HTTP

Hi All,
We are currently encountering a firewall rule problem. The following are the steps we
have done so far:
Default Outbound Policy: Allow Always
IPV4 Rules - Delete all firewall rules we have created and made a single firewall rule to block
                            outbound HTTP for a single IP Address
                 - Delete all firewall rules we have created and made a single firewall rule to block
                            outbound HTTP for a range of IP Address
                 - Tried making "Block by schedule" Action on port HTTP on a single and a
                             range of IP Addresses
                 - We have tried blocking HTTPS / POP3 / SMTP / IMAP and was successfully
                             blocked but not on HTTP
Services - Created a Custom Service blocking Port 1-65535 but still workstation can still access the internet.
MAC Filtering - Checked MAC address filtering and Policy for MAC Addresses listed below is set to
                              Block and Permit the Rest and added the MAC address of the workstation we want to block
                              still the workstation can access the internet.
IP/MAC Binding - We have also binded the MAC Address and IP Address
Content Filtering - Only content filtering works - blocked URL
We have also tried doing all the IPV4 Rules with the Default Outbound Policy: Block Always and all
the firewall rules action set to allow only those services that needs to be permitted.
Still blocked workstations can still access the internet.
Firmware Version: 1.1.42
Thanks

Hi Karl,
This looks like a bug in build 1.1.42. Please upgrade your
image to the latest build 2.1.18 which fixes the problem.
Let me know if the upgrade helps.

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.

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?

Wrong firewall rule?

Hi all,
I just found out that I got a strange rule "allow ip rom any to any" at the bottom of rule set. I wonder that where this one came from? Is it safe and how to delete it?
Thanks!

From your screenshot, it appears that rule should have zero effect due to the rule just before it which denies ip from any to any.
I have found the command-line tools to work much better than Server Admin's GUI firewall page.
sudo su root, then
edit: /etc/ipfilter/ipfw.conf to set your firewall rules
ipfw show command lists currently loaded firewall rules.

RV120W Firewall Rules

Hi,
I have several problems with RV120W Wireless-N VPN Firewall :
1 - I can't delete firewall rules from web interface, when I try, a error "Selected firewall rule(s) deletion has failed" (cf attache file)
2 - I want to be able to send ping (or others) to a wifi connected device from WAN, i have a rule to allow all traffic from wan to lan in any protocol. When i try to send ping lan interface, there is impossible.
Thanks,
Benoit MENARD

Dale,
what address are you using to access the internal company websites (IP address or domain name). More than likely, port forwarding rules need to be configured for port 80 to go to internal address of the web server.In order to configure rules for services not available in the list, you wll need to create a custom service. After the service is created it will appear at the bottom of the services list. If you need further assistance you may have to call 1.866.606.1866 and open a support ticket.

ASDM Firewall Rules getting unchecked

Has anyone seen where ASDM will uncheck firewall rules?
I am using ASDM 7.1(1)52 on an ASA5520 running 8.2(2)17
but I have seen this behaviour on earlier versions of code.

Hi,
The only thing that would be common and expected behavior would be the access-group command getting deleted which would uncheck all the access rules on the ASDM.
Thanks and Regards,

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.

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;
INetFwPolicy2 *pNetFwPolicy2 = NULL;
INetFwRules *pFwRules = NULL;
INetFwRule *pFwRule = NULL;
long CurrentProfilesBitMask = 0;
BSTR bstrRuleName = SysAllocString(L"SERVICE_RULE");
BSTR bstrRuleDescription = SysAllocString(L"Allow incoming network traffic to myservice");
BSTR bstrRuleGroup = SysAllocString(L"Sample Rule Group");
BSTR bstrRuleApplication = SysAllocString(L"%systemroot%\\system32\\myservice.exe");
BSTR bstrRuleService = SysAllocString(L"myservicename");
BSTR bstrRuleLPorts = SysAllocString(L"135");
// Initialize COM.
hrComInit = CoInitializeEx(
0,
COINIT_APARTMENTTHREADED
// Ignore RPC_E_CHANGED_MODE; this just means that COM has already been
// initialized with a different mode. Since we don't care what the mode is,
// we'll just use the existing mode.
if (hrComInit != RPC_E_CHANGED_MODE)
if (FAILED(hrComInit))
printf("CoInitializeEx failed: 0x%08lx\n", hrComInit);
goto Cleanup;
// Retrieve INetFwPolicy2
hr = WFCOMInitialize(&pNetFwPolicy2);
if (FAILED(hr))
goto Cleanup;
// Retrieve INetFwRules
hr = pNetFwPolicy2->get_Rules(&pFwRules);
if (FAILED(hr))
printf("get_Rules failed: 0x%08lx\n", hr);
goto Cleanup;
// Create a new Firewall Rule object.
hr = CoCreateInstance(
__uuidof(NetFwRule),
NULL,
CLSCTX_INPROC_SERVER,
__uuidof(INetFwRule),
(void**)&pFwRule);
if (FAILED(hr))
printf("CoCreateInstance for Firewall Rule failed: 0x%08lx\n", hr);
goto Cleanup;
// Populate the Firewall Rule object
pFwRule->put_Name(bstrRuleName);
pFwRule->put_Description(bstrRuleDescription);
pFwRule->put_ApplicationName(bstrRuleApplication);
pFwRule->put_ServiceName(bstrRuleService);
pFwRule->put_Protocol(NET_FW_IP_PROTOCOL_TCP);
pFwRule->put_LocalPorts(bstrRuleLPorts);
pFwRule->put_Grouping(bstrRuleGroup);
pFwRule->put_Profiles(CurrentProfilesBitMask);
pFwRule->put_Action(NET_FW_ACTION_ALLOW);
pFwRule->put_Enabled(VARIANT_TRUE);
// Add the Firewall Rule
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?

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

Fri Jan 7 13:43:14 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=UDP SPT=60737 DPT=53
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

Delete obsolete business rules

Hi experts,
I'm currently working with Hyperion Fusion Edition 11.1.1.2.
In calculationmanager I created 10 business rules for an application.
I then deleted all of them in one step (marked all then right click "delete").
The intenet explorer browser freezed showing "DELETE".
I then closed the browser and logged back in, imported the new 10 business rules to the application and deployed them.
It is very wierd that I still have the old 10 business rules which I deleted plus the 10 new business rules.
The old business rules are not to be found either in system-,deployment-, or list-view but can be found in planning application.
Is there workaround to delete the 10 old business rules which I cannot see in calculation manager and still exist in planning?
Many thanks
Ed

Hi,
There is a Java API available for Oracle Business Rules, see: http://docs.oracle.com/cd/E23943_01/apirefs.1111/e10663/toc.htm. E.g. for adding buckets to bucketsets, adding or adding, deleting, or reordering rules in A RuleTable.

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.

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