• Several Internet gel 30 seconds + DDoS attacks

  I get anywhere from 3 to 10 per day ddos attacks, many of them coming from the same IP it happens every day and it's really annoying. I tried to install some VPN and DDoS protection free programs, with no help. These 3-15 attacks, I have to deal with every day are stored in my Netgear router logs and one here that I had a few days ago.

  Not only that, but whenever I play CSGO or Minecraft, my internet freezes (including voices, stopping in Skype, mumble, teamspeak, etc.) and it happens every 20 to 90 seconds about 2 to 6 seconds, and sometimes, there's a small 1-2 second freeze thereafter.
  I don't know how many of you play competitive Minecraft and CSGO, but if you do, you know how much a tip of ping or huge internet gel box will cost your game sometimes, and that was really pissing me off.

  More information:
  My internet is Time Warner Cable (live in the middle of nowhere), my router is a Netgear WNDR4500v2 I got before all this happened. Initially, when I got the router, I had no lagspikes, or at least none that was like that. Then I got another modem, then there was some lag every few minutes or so for like 2 seconds, which was not really that big of a deal, I only noticed in CSGO, but a week or two there, I got a new modem, and it was fine for a few days, until it was like 4 or so days ago I started to have the issue I described above.

  Any help would be great, I tried a factory restore my computer and I did so no games or software updates in the background, but not luck. If necessary, I can give more information on the issue and my software/internet, etc.

  This post is too similar to my problem: https://community.netgear.com/t5/General-WiFi-Routers/WNDR4300v2-lag-spikes-every-20-30-seconds/m-p/...

  Are you running wired or wireless?

  If you bypass the router, you get the same ping spikes?

• Do not uncheck the box "enable memory protection to help migrate online attacks."

  Original title: Internet advanced setting properties is locked can I unlock

  While checking the settings, I have double clicked on security settings, to enable memory protection to help migrate online attacks. Now it is display lite and I can't UN verifiez_ the. How can I reset to unlock and return to the display as well as others?

  Hi DJ Georgetown,.
   
  -What version of IE are you using?
   
  Login to an account with administrator rights to uncheck this option.
   
  Data Execution Prevention (DEP) is a security feature that can help prevent damage to your computer from viruses and other security threats. Harmful programs can try to attack Windows by attempting to run (also known as execute) authorized code in the memory of your computer for Windows and other programs. These types of attacks can affect your programs and files.

  DEP can help protect your computer by analyzing your programs to make sure they use the memory of the computer safely. If DEP notices a program on your computer using memory incorrectly, it closes the program and notifies you.

  Microsoft does not recommend disabling security DEP settings. But still if you need, you must be an administrator to disable the DEP settings.

  You can use the following parameters to change data execution prevention settings.
  • Click the Start button and right-click on my computer and choose Properties.
  • Now you need to click on advanced system settings
  • Now, go to Performance and click settings.
  • Now, go to Data Execution Prevention and just click on turn on DEP for all programs and services except those I select.
  • Now, choose the program of desire to which you fork DEP. When you are finished, click OK.
  • Restart your computer.

• Protect a router

  Hello

  It is advisable to protect a router itself against access using access control lists?

  I ve read somewhere that ACL can block all but the packages sent directly to the router, but that's obviously not true.

  Consider the following scenario: I ve I used as a gateway router IOS VPN; It s located in a demilitarized zone, beside this router are some other machines as servers and other routers. The VPN gateway (and the demilitarized zone) are naturally protected by the firewall on the outside, but what happens if someone sings one of systems DMZ and starts to attack the VPN gateway? That's what I want the VPN router to protect against. So I could use the vty access classes

  and so on, but why Don t just use an inbound access list on the DMZ Interface like this:

  int-acl_f1/0-in extended IP access list

  allow any host 192.168.1.1 esp

  allow any host 192.168.1.1 eq isakmp udp

  allow any host 192.168.1.1 icmp

  deny ip any any journal entry

  .. where 192.168.1.1 is the router itself.

  So there is only allowed VPN and ICMP traffic

  for the routers DMZ Interface and example

  Telnet and other things are denied.

  Is it a good practice to ensure a router or not

  I misunderstood something?

• Sometimes I disable my internet router intentionally & Firefox implements a warning window to this being off topic. How can I disable this alert window?

  When I go out or go to bed at night, I disable my wireless internet router. Sometimes I turn off when I just do something that doesn't require me to be online. Whenever I do this, Firefox continues implementing a warning window every two minutes telling me that I have no connection (that I know). How can I disable this window alert so it isn't keep appear in the middle of a game or a document that I do?

  Its an addon, not firefox.

  Start Firefox in Safe Mode to fix the problem and to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/tools > Modules > appearance).

• The captain El VPN Internet routing

  I was able to set up a virtual private network and can connect to it. But can not get external ip addresses.

  At one point, I was able to connect to outside the VPN network. I could check my IP to show that I was on my VPN network when I was somewhere else. I don't know why, but at some point it stopped working. The only thing I did at one point was to reboot the machine, but I don't think he was.

  I've followed this how-to:

  https://macminicolo.net/blog/files/setup-a-VPN-server-with-El-Capitan-Server%20. HTML

  Redirection of DNS servers are on 10.0.1.1, 127.0.0.1

  The VPN DNS is set to 10.0.0.1

  After that stuff stopped working, I ran the script:

  bash <(curl -Ls http://git.io/1UlbJQ)

  But that just copy my entires I made by hand, so I deleted everything that has been redone.

  I'm guessing there is something I am missing, or if there is a way for me to check if the routing is or is not happing maybe that would have me idea in how to get this back on track.

  Yes on the client, I send all traffic over VPN set. When you use the VPN, I can not access google.com.

  Nslookup works

  Ping does not work with external areas, also if I ping IP that it doesn't.

  The last time I saw a similar problem here report in these forums it was down the routing tables, as explained below.

  • You have all the traffic of customers being forced to go through the VPN to the office network, I can tell that you are able to communicate with devices on your corporate network
  • However, you can not contacted devices on the Internet once connected via VPN

  It's probably to the fact that your office network is a network firewall on that or Internet router and one of them is the default gateway Internet for your corporate network. So the traffic will go since your Mac client via VPN on the office network, on office of firewall/router network, via the firewall/router to Internet, via Internet on the remote site, then back across the Internet to your router/firewall, then... get lost because your router/firewall knows where to send it to reach your remote Mac VPN client is not on the network of the company.

  What you need to do is add a "static route" tell your firewall/router that all traffic destined to go to the network that you have defined for VPN clients should be "routed" via the VPN Mac server LAN IP address.

  Note: According to the guidelines of Apple VPN clients must be on a beach in separate to your LAN network, so if your LAN is 10.0.1.x/255.255.255.0 then your range of VPN client should perhaps 10.0.2.x/255.255.255.0

• Protected Internet mode

  Hi, I have a TouchSmart tm2 laptop with Windows 7. I noticed that my protected Internet Mode was turned off during the last 2 weeks. Twice I called HP Customer Service was on the phone for more than 4 hours between the 2 calls & again, they were not able to turn it back on. Does anyone have any suggestions? Thanks in advance.

• There is a security risk to plug the internet router management on the LAN port?

  I have to install an ASR1001 on the internet for my business.  I noticed that the ASR1001 has a dedicated management port and I was wondering if it's a security risk to have this mangment port directly connected to my local network, so that I can mange it from my office.

  I want to only run the ASR of this port and I will no management through its public IP address.  Is it possible for a malicious user to compromise the router then have access to the network but this management port?

  I'd say it's a reasonable risk.  If you intend not to allow future management of the public side sessions you are a good start, implementation of protection against attacks.  Combine that with a few basic hardening, for example to disable source routing, directed broadcast, ip proxy arp, finger, as well as an ACL on the management interface so that all traffic from an untrusted interface on the router would be unable to receive return traffic.  In addition, the management vlan must be a dedicated vlan.  I would not fall in the same vlan in that your office is located.  Better design would be to fall into a dmz (acl on the router's management interface would be redundant in this case) and to apply the rules of the firewall.  However, if this is not possible, order access to routing on the ASR as well by including only a 32 road to your management station via the management VLAN interface.  Also, remove any redisribution or advertising of this management interface in your routing protocol.

• Extension of wireless network with 2 capsules of time falls internet router

  I have a fiber broadband from the Danish supplier, TDC. A port on the router, I connected a TimeCapsule 1 generation and one of its ports, I have a cable to a new TimeCapsule in another room. The first TC is set to create a wireless network and the new TC is set to extend a wireless network. Both are on the same wireless name and password and both have the clipping value. This is according to the instructions that I found here on the forum.

  HOWEVER. When you use this router configuration mentioned above keeps falling and interruption of the Internet connection. What could happen?

  If I let the TCs create two wireless router maintains a stable Internet connection.

  On each TimeCapsule, there are a number of devices connected to their respective ports. All IP are chosen by DHCP. I assume that the router is the only DHCP server and that the CHT are not IP for connected devices.

  Any help to solve this is appreciated.

  To connect nr2 nr1 TC but not the TDC router. The ports on the TC are just parallel connectors (except the one that connects the modem). Then you must set both to create a network: you have two networks.

  Then give them the same name and password (or not, what you want).

  When you want to extend the network, do not connect the cable to the nr2, but you should put nr2 where he received the Wifi of nr1 and then extend it. This also works, but is much less bandwidth.

• Router (IPSec)-> INTERNET-> Router (IPsec) where to put the TUNNEL IP POOL?

  Hello

  I'm still learning the VPN (IPsec), I was able to create a tunnel between my PC and my router, but now I want to connect two routers:

  F0/1=192.168.0.1 ROUTER A-> INTERNET-> ROUTER B F0/1=192.168.10.1

  Both routers receive an IP address from my ISP, I can't do a ping to a site at the other site, I mean, I am able to PING ROUTER A from ROUTER B with the ISP addresses and otherwise.

  Two ROUTERS have the same configuration, except for the IP addresses and the ACL, they are opposite.

  I think I know what I did wrong, but I don't know how to solve: the TUNNEL need also an IP from a POOL where should I put up, the ROUTER A or ROUTER B?

  Didier, there are a number of things missing in your config file to make it work, what I can say fa0/1 is inside and the fa0/0 are outdoors. There is no NAT translation to activate the computers inside the network, allowing access to the Internet. You will also need to exclude the EIGRP NAT roads in order to reach the remote network. Each router must have a default gateway to the Internet, this should be done with the following command:

  IP route 0.0.0.0 0.0.0.0 fa0/0 dhcp

  This will use the default gateway of the DHCP server that assigns IP address on fa0/0. Once that each router has a path to another and the tunnel connects EIGRP will handle the rest given the information to the router 90, this is the spectacle of one of my spoke routers route:

  NTR-2620XM #show ip route
  Code: C - connected, S - static, mobile R - RIP, M-, B - BGP
  D - EIGRP, OSPF, IA - external EIGRP, O - EX - OSPF inter zone
  N1 - type external OSPF NSSA 1, N2 - type external OSPF NSSA 2
  E1 - OSPF external type 1, E2 - external OSPF of type 2
  i - IS - Su - summary IS, L1 - IS - IS level 1, L2 - IS level - 2
  -IS inter area, * - candidate failure, U - static route by user

• New internet router but no connection to internet (local connection only)?

  Hello

  I have a computer laptop compaq presario cq60-307sa, I changed recently to talk about my house bt to my internet hub. My computer connects with the router but it won't no matter what internet access and it says "local access only". Internet works fine on my phone, so I know the router is fine and my computer to connect to my internet work without problem. I spoke to talk, but they said I have to reconfigure the computer by going to the computer set up menu but I don't know what to do. I also did the troubleshooting thing, but it didn't work. Can anyone help?

  Thank you very much

  Phil

  Hi, Phil:

  What model network adapter do you have in your laptop?

  Perhaps a driver update is required for your wireless card work with your new router.

  If you have the Atheros AR5007 wireless card and the driver date is before 2010, I can almost guarantee you that is the question.

  Please see my thread on the link below.
