The ip given belongs to the APNIC range 59.145.197.0 - 59.145.197.63<br />
Are there any further network subdivisions and routers in place?<br />
At which points do you have control?<br />
Using static arp entries at the parent router might help...
</div>


<div>
sir we dont have router we get a lan wire from service provider and these static IP can i restrict them. if router needed which router is required pls specify model if possible tell cisco router model <br />
<br />
thanks<br />
<br />

<div>
Well, about any router would do.<br />
However, if you get a lan wire which serves the complete net range, you'd cut off the back routes, so an internal router is not really an option..<br />
But you *do* have a firewall, don't you?
</div>


<div>
Dear sir<br />
we dont have firewall yet. pls suggest me which firewall is good. how to use this firewall to block this type of incident.<br />
<br />
thanks<br />

Are you serious? I'm almost panicking...<br />
Indeed, I see several MS windows machines which are blocking access to the windows typical ports 135, 137-139, 445 (in fact this is what makes me think they are windows in the first place, but see below). But others have telnet, http, printer ports,vnc and more.<br />
In fact the Exchange server dhbvnlm.DHBVNL.local has 32(!) ports open to the internet.<br />
<br />
At one of the IPs you seem to have a D-Link router (or D-Link webcam?) and at one a ML-3050 Series printer (name: SEC00159926E72C), so apparently not all machines are Windows boxes. However, do yuo really want the world to access all your resources (I just produced a demo page on the ML-3050 to show you how seriously open your net is; this required no cracking at all, just clicking through a publicly available web page without the slightest &quot;don't do that&quot; notes or other obstacles) - and also the CLX3160FN invites everybody to upload arbitrary print file <br />
<br />
If you really don't have a firewall, I'd bet that at least some of your hosts are seriously infected.<br />
Leaving a net open like this without a &nbsp;firewall is ver dangerous!<br />

dear sir<br />
<br />
thanks for your help. now please tell me how can i stop this which firewall i have to use. pls tell me in detail and how can u print the test page without my id and password of computer.<br />
<br />
thanks<br />

</div>


<div>
Dear sir <br />
now i have changed the settings pls give me self print command from outside pls do it and let me know<br />
<br />
thanks<br />

</div>


<div>
The printers have web interfaces from which a lot can be done. And of course they also act as network print servers. If you don' t need them accessible from outside, you may want do reconfigure the network settings and simply remove the default gateway.<br />
This is of course no replacement for a firewall. In my opinion *any* firewall will do (esp. any firewall is better than no firewall). I personally usually use linux vased software firewalls like ipCop or shorewall. But you can also get appliances. However, maybe someone else can jump in for recommendations.

Q: What firewall is better than no firewall?<br />
A: ANY firewall is better than no firewall!<br />
<br />
In short -- it doesn't matter. &nbsp;If you like Cisco equipment, then look at a PIX. &nbsp;If you like SonicWall (my favorite), then look at them. &nbsp;Or get a DLink. &nbsp;Or a NetGear. &nbsp;Or a WatchBox. &nbsp;It doesn't matter -- just get SOMETHING! &nbsp;<br />
<br />
Each manufacturer will have various models, depending on the size of the network, the number of concurrent users, the link speed, and the performance, and some even come with additional features link VPN, SSLVPN, wireless gateways, and more. &nbsp;Look for something that provides easy management capability (one of the reason I like SonicWall), along with any other features you need. &nbsp;Start with the SonicWall TZ180, TZ190 or TZ210 lines for smaller sites, or look at their larger boxes for larger sites.<br />
<br />
A firewall does a few basic things. &nbsp;First, it protects access to your network from the big, bad, outside world, only allowing ports that you specifically open up to that world. &nbsp;This prevents people from doing nasty things (like using up all the paper in your printer). &nbsp;Another thing it does is provide additional protection via Network Address Translation (NAT), which provides for a local set of network addresses, and a LIMITED set of public addresses. &nbsp;As such, you can define exactly which public addresses should be used, and to which computers they should be assigned. &nbsp;Everyone else gets a &quot;private&quot; network address and is therefore inaccessible from the public 'Net. &nbsp;This should address your original problem of taking up too many public addresses, too.

how to block user to use static ip

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.

Networking Protocols

Network Management involves issues that are independent of specific hardware or software, including email policies, upgrade planning, backup scheduling and working with managed service providers for Desktop-As-A-Service (DaaS), Software-As-A-Service (SaaS) and the like through the use of tools, coupled with manufacturer standards, best practice guidelines, policies and procedures plus all other relevant documentation. Network management also includes monitoring, alerting and reporting, management reporting, planning for device or service updates, the backup of configurations, the setting of key performance indicators and measures (KPIs/KPMs), associated service level agreements and problem records as part of the IT Service Management (ITSM) framework.
