How do I refuse to receive packets from an IP address? 5

Log in to the router, enable the firewall, and filter IP addresses

For example, the Rising 2009Open it with detailed Biku settings. In Network Monitoring > Rule Settings > IP Rules.

Select"increase".Enter a name for the rule. The rule applies"All IP packages".

Then the next step is to select a newspaper formula. Finish. And then again"Applications".

OK".That's it.

Write an access control list in your extranet-connected router.

Afoo! You go to the firewall to set up a sprinkle and add a blacklist!

If you want to disable all connections to an IP address or a port to a specific IP address, you can only use ACLs.

ACL is actually very simple, it depends on the brand and model of your switch, some switches have a web control page, and you only need to specify the source IP address, the destination IP address, and the service port you are applying to.

The few upstairs seem to be a little wrong!

Huh!Make a statement. Through the switch that does not call"Packets"Rather"Data frames"

If it's like what you said it would be. Either Layer 3 switching or routers can be used as ACLCISCOs, and the device can use an extended ACL

access-list 100 deny ip host host applied in the outbound direction.

H3C devices can be adopted.

acl number 3000

rule deny ip source destination destination-port destination-port

I think so. Huawei's memory is not clear!

Use this command to prohibit any communication with .

access-list 100 deny any

Well, you change the IP, or redo the first new installation, or don't use your current group, change it, see if others still can't find it, and then don't go to Qindong, just take the plate, hehe.

Step 1: Open "Control Panel Management Tools Local Security Policy", then right-click "IP Security Policy", select "Manage IP Filters and IP Filter Actions" on the local machine, uncheck "Use Add Wizard", add a new filter rule in the list of Manage IP Filters and IP Filter Actions, enter "Access Denied" in the name, and then press Add, select "A specific IP address" in the source address to fill in the IP address, select My IP address as the destination address, and the protocol type is"Any", remove "Mirror". Meantime.

The front check is set.

Step 2: In "Manage Filter Actions", uncheck "Use Add Wizard", add and enter the name "Block" in General, and set the security measure to "Block". OK

Step 3: Click "IP Security Policy on Local Machine", select "Create IP Security Policy - Next - Enter the name as "Access Denied", uncheck "Activate Default Corresponding Rule", Done, in the pop-up "Access Denied Properties" window, select "Deny Access" in the IP filter list, select "Block" in the filter period action, OK, and then right-click "Access Denied" and enable.

Finish. If you select "Any IP Address" as the source address, "My IP address" as the destination address, and "ICMP" as the protocol in step 1, you can prevent other people's ping attacks, which means that outsiders can't ping you at all!!

You can use the IP network access rules of the firewall to set the other party's IP to prohibit ping.

Just deny the software or port in the firewall.

Your built-in firewall in Windows has a deny rule where you write this IP address. And turn on this firewall function.

If you have installed a fire resistance, you can set it in the firewall.

I use Rising Firewall, which has an option to set an IP blacklist!

IPs in the blacklist will not be able to access the machine.

Is there a connection with him?

Use the netstat -ano command in cmd to see which process is connecting to that IP address, and then end it in Task Manager, if it's not a system file, you can delete it.

In Group Policy, you can set to deny this IP

If you have installed a fire resistance, you can set it in the firewall.

89 big brother said that IP is dead

What kind of system is you?,2003 has an ipsec policy that can be.。。 XP,You can use XP's built-in firewall to achieve this,,It's better to know what port the other party is sending through.。。 Otherwise, you'll have to get a software firewall.,,Use Fair's personal firewall.,It's free.,I'll use this now.。。

If it doesn't work, you can just change the IP.

The best way to do this is to use a firewall to filter specific IPs or set the following in Group Policy.

Blocked in the hosts file.

IPs to be banned

You can set it inside the firewall!

With a card, look at the network connection, see which program is using that IP, and kill it!!

Norton is not good, you use McCafe.

His protection is so that hackers can't rewrite anything about you.

You can go and see how it works.

I won't say much here.

It seems to be poisoned. It's useless, the virus must be a **server, and besides, there is a backdoor on your computer. They will also send from other ports. If you don't have it, it's still antivirus, if it doesn't work, just reinstall it

In Group Policy, you can set to deny this IP

You can use a firewall or Windows Group Policy. Group Policy Steps:

1) Click Start--Run, and enter "Open Group Policy" in the Run box.

2) Open Computer Configuration--Windows Settings--Security Settings, right-click "IP Security Policy, Local Machine", and select "Create IP Security Policy" in the pop-up menu to open "IP Security Policy Wizard".

3) Set the name of the IP security policy, such as "No ping", and enter a simple description. Secure Communication Request: Check "Activate Default Response Error".

Default Response Rule Authentication Method: Select "This string is used to protect key exchange", and then enter some characters in the text box, such as "pcdigest".

To create an IP security rule, select Properties and click Finish to open the Properties dialog box.

4) In the "Disable ping" attribute window, click the "Add" button, make the following simple settings in the "Security Rule Wizard", and press enter all the way.

Authentication Method: Select "This string is used to protect key exchange", and then enter the original set character in the text box, such as "pcdigest".

IP filter list: Click Add Add and set the source address to My IP address, the destination address to Any IP address, and the protocol type to ICMP protocol. Once you've added it, you'll be able to see the newly created filter in the IP filter, select it and click "Next" to continue.

5) In the Group Policy window, click "IP Security Policy, on Local Machine", in the window on the right, you will be shown the newly created security policy that prohibits ping, right-click on the policy, select the "Delegate" command in the pop-up dialog box, and exit Group Policy. At this point, others will no longer be able to ping your machine.

Kingsoft NetGuard chooses to deny ping access.

Yours is a local area network, the local area network will generally have a network server to manage in a unified manner, of course, you can check your traffic, look at the route, or that sentence, if you have a network server in the bureau to manage the Internet, don't think about it, the server route is not our small family that small router can be compared, the router in addition to one is, you first use the optimization master to see what your gateway is, the route is from there.

The best way is for you to let the family play during the day, and you can just turn on the computer all night at night, and you don't delay.

You must have been told by someone else who felt that the internet was slow.

You just have to spend time with them and do whatever you want.

You disable your network connection for a while, and then start it and it's OK, and others will look at the number of packets from the new connection.

The ICMP packet is what we often call a ping packet... This means that a computer with an IP address is attacking you through ping commands or ARP, but you don't have to be afraid to block it, you'd better use 360 Security Guard and turn on ARP Firewall, which is more secure.
