View 4 RepliesIs there anyway to block a DDOS attack? I dont know to much about DDOS attacks and how they work, but i think i understand a little bit of it. Is there no way to configure a firewall to detect rapid, spontaneous,continuous amounts of fragmented, random data coming from an IP address? Wouldn't the data coming in from a DDOS server be somewhat distinct from data that flows normally

My network is running on a Linksys WRT160N router that has been flashed with DD-WRT v24-sp2 (04/23/10) std firmware.I have tried "Website Blocking by URL Address" and "Website Blocking by Keyword" in my router settings but neither seem to take effect.
partition the departmental IP network address block to create a staff and a student subnet. Each of these will be identified by its own network address and netmask. It is university policy that you must be economical with the IP addresses. That is, the subnets must be as small as possible, but they must be large enough to accommodate the maximum number of hosts you were given. Also, it is university policy that the respective gateway router to the outside world should always be given the highest possible host IP address in the subnet. The student subnet should have a higher IP network address than the staff subnet. The network must be able to support up to 60 machines on the staff subnet (not counting the router) and up to 120 machines on the student subnet (also not counting the router).
IP address/netmask
University network address127.158.128.0
University network mask255.255.192.0
University internet gateway IP address127.158.191.254
Department network mask255.255.254.0
Department router address127.158.129.254
Suppose that the network address of the departmental network is 127.158.128.0 (calculated by AND between Dep network mask and Dep router address)I know that 60 machines would use 6 bits for the staff subnet.the netmask of staff would be 255.255.255.192.how can I figure out the the IP network address of the staff subnet.I have worked out the range for the staff subnetwork.
127.158.128.0 - 127.158.128.63
127.158.128.1 = Gateway address
127.158.128.63 = Broadcast address
Now how can I calculate the IP network address of the staff subnet?
Well I went to command prompt and typed command ipconfig /all and saw the ip address my system was configured to. Dunno why, but I manually set that ip address in my IPv4 internet settings and got access in my hostel. Now suddenly the access is gone. What should I say, the ip address that I set my laptop to has been shut down ? It doesnt work any more? How do I get another IP address like that which gives me no restricted browsing? What does the admin do in the laptop that suddenly it gets unrestricted browsing privileges?

View 1 Replies View RelatedI have one dedicated IP issued to my home, along with another dynamic one if I need it(but I don't use it). I have a webserver, mail server, and name server up and running on a single machine exposed to the internet with my static IP. I have a domain name registered to my IP address. My webserver and name server work great, but I am having difficulty with the mail server. In order to have mail work correctly, I have been told that I need to get reverse DNS setup for my domain (something I had neglected to do). My nameserver responds to reverse lookups correctly when issued locally, but it looks like queries from the internet never reach it (I think my ISP catches requests upstream). I contacted them and they put a PTR record in for my IP pointing to ns1.mydomain.com. This all works fine, but the thought occurred to me that if in my hosts file I put my MX record in as mail.mydomain.com., any mail clients that do a reverse lookup of my IP won't get mail.

Of course, there are always wireless solutions, but the options around here are pathetic and comparable to dialup. They were content with this; I moved back in with them for the time being and am not.y solution has been to dump just shy of $1,000 into a point-to-point wireless bridge setup that claims to have a range of 5 miles non-line-of-sight. I have one antenna set up four miles away on top of a building that has high speed internet.Unfortunately, I was a stupid fool and set that end up without enabling security, thinking that it wasn't a big deal. Nobody in that town has a mind for anything but farming and drinking. That was my mistake. Some asshole set a password and forced me to do a factory reset on the access point and now I can find no IP address. It's like it only reset halfway to factory defaults or something
View 6 Replies View RelatedIn my router I can set rule that all traffic incoming to router's extAddr:8888, is forwarded to my intAddr:8888. But I also need reverse rule that packets originating from intAddr:8888 are translated to extAddr:8888. Can I do that? What technique can I search on google to find more information, because it is not port forwarding. I would calll it reverse port forwarding or static port address translation, but I do not find anything useful in internet searching these keywords.

View 9 Replies View RelatedI am trying to set up a WAP4410n Wireless access point and add to my home network. One problem I can't seem to get around. The IP adress range setup does not accept 1 (example 192.168.1.245) as a range setup for IP address. How do i get in communication with the unit when I can't view the setup due to the factory default set as 192.168.1.245? If it were 192.168.0.245 I could easily change my routers IP range to include it.
View 0 Replies View RelatedI have a high speed wireless DSL router from my ISP (Telus). I use one port off the router to connect directly to my desktop computer. Another port is connected to a switch to which ethernet cables to three other rooms are connected. My problem is that when I connect my Bell PVR (9242) to the 'switched' ethernet cable, I'm apparently not able to get a dynamic ip address, which the Bell unit requires, and can't connect to the network.can I connect another router, in place of the switch, to deliver dynamic IP addresses to whatever I connect to the ports in the other rooms in my house?

I have already set up a dynamic IP address which points to my router at home. In my home network I have multiple PC's that I would like to access from the internet. I would like to achieve this without needing to change my port forwarding rules on my router each time...
My thoughts are that I use a single dynamic IP address pointed to my router. My router then forwards to a server with some sort of software that can then forward to the correct PC based on the host name.
So I have 3 domains set up all pointing to the router's IP address:
dest1.domain.com -> 41.xxx.xxx.45
dest2.domain.com -> 41.xxx.xxx.45
dest3.domain.com -> 41.xxx.xxx.45
The router is not smart enough to redirect by host name, so it will just forward everything to 10.0.0.20 The server based at 10.0.0.20 must then have software to now redetermine the target based on the host name. The rules would be set up as follows:
dest1.domain.com -> 10.0.0.22
dest2.domain.com -> 10.0.0.24
dest3.domain.com -> 10.0.0.26
I want to block a computer by its MAC address, not by IP, from accessing Internet.

View 7 Replies View Related I've came across IP address that aren't enough for some users in the company. The IP addresses are more than enough to cater to the user's notebook or PC. However, some users does not know that there are actually limits to the IP we have, so quite a number of them actually uses their mobile / pads to tap the company's wireless.
I was wondering if i could restrict that particular user from tapping onto the network. I know it sounds a bit impossible because DHCP doesnt have that smart function to block whoever we sees deemed as a "nuisance".
Bought DIR-655 from Amazon. Rev. B. Come with 2.00NA firmware. Updated to latest one, and there are a lot of problems, to most of them, I was not able find any solution. Here they start:
1. WIFI SPEED PROBLEMS.No matter what speed, parameters, channel, mode, etc I select, router keeps working on 20mhz channel width. So I never get speeds above 65 mbit. In absolutely same conditions, my DIR-300 B1 (with DD-WRT firmware) gives me stable 150mbit. SO I KINDLY ASK, MAYBE THERE IS A WAY TO FORCE "40 MHZ ONLY" OPTION?
2. PASSWORD PROBLEMS.Router came with no admin password, I enter new password, hit "update" it says - wait 20 sec, after that, login page is displayed, but, new pasword does not works! since it asks again for empty password!
3. FILTERING PROBLEMS.I need to block certain IP address to be accesed by all my computers. Say this is 111.111.111.111 . So I added inbound filter rule, to block access to that IP. It does not works - IP is still accesible.
4. MORE FILTERING PROBLEMS.Since above mentioned method does not works, I have to use "ACCESS CONTROL" feature. It does works, but it causes another problem, with access control enabled, all webpages with form submit stop to work. For example, if I'll have that feature enabled, when I press "post" on this webpage, it instantly will go to "this page cannot be displayed".
I bought this router solely for one purpose - I was happy with speed of my DIR-300, but I needed gigabit for my computers. So I thought, instead of buying separate switch, I'd better buy a router with gigabit. I was suggested to get TP-LINK 1043, since it's quite popular, alternate firmwares available and so on, but I refused to buy it, since I thought that some chinese company does not worth my attention. So I bought this D-Link (for almost 2x price of TP-Link) and having huge problems as you can see.
I want to do what I thought would have been a simple enough task - block my kids phone/computer after certain hours. Instead of blocking the specified MAC address(es), all my computers does not have internet access. As soon as I disable the policy, internet access is on again. Here's what I did:

I've been keeping an eye on my IPS report tab lately and have been watching a large number of ICMP_SMURF and DOS attacks originating from chinese ip address's. I know I can probably block the offending ip's through the ip based acl tab in the firewall settings, but I'm kind of a newbie how I can block certain ip's from touching my router?

View 4 Replies View RelatedI have a Time Warner Cable business class service with no static IP, with a wireless modem which is plugged to a CAT5 distribution panel. On the jacks (2 other rooms on the house) I have a Linksys E3000 and a Linksys Valet router for signal boost and gadgets usage (TV, cameras, etc).The main router (TWC) has it's own external IP which TWC assigns to me and internally distributes via DHCP the range 192.168.0.x. With that said:
- The E3000 has a 192.168.0.6 IP -- this is fixed setup on the TWC router (ubee brand) by MAC address
- The Valet has a 192.168.0.7 IP -- this is fixed setup on the TWC router (ubee brand) by MAC address
- The main router has the 192.168.0.1 as the gateway and web-interface
Whenever I connect something to the E3000, it is distributing the 192.168.1.x range and the valet 192.168.2.x range.That works perfectly for my home based business until I decided to use more stuff on the network such as a IP printer, IP cameras, etc.
- The IP cameras are connected to the E3000 due to signal strength and I have manually assigned them the 192.168.1.15 and 192.168.1.16 IPs and ports 9001 and 9002.
- The printer is connected to the E3000 and I have manually assigned the IP 192.168.1.30.
Issue 1: Port forwarding On the main router (TWC - UBEE) I have tried to setup a port forwarding by informing the Local IP as 192.168.0.6 (E3000 IP), Internal Port 0, Public Interface IP (0.0.0.0), Ext Start Port 9001, Ext End Port 9001, Protocol - Both, Enabled Yes. On the E3000 I did the same config (screen shot attached e3000.png).This is not working properly. I can't get into the camera.
Issue 2: Printer/ The printer is only accessible if I connect to the E3000 (because it is on the 192.168.1.x network)
Issue 3: How to configure all the devices on the same subnet? If I want everyone to be on the 192.168.0.x network, how to configure properly the E3000 and the Valet? I have tried to force them into the same network but it would not work properly. It would not get an IP from the UBEE router (main).
