Cisco WAN :: Anti Spoofing With 3825

May 5, 2011

Is there any way  to configure 3825 to ensure that all packets have a source IP address  that matches the correct source interface (similar to ASA's 'ip verify reverse-path interface')? Currently, we manage anti spoofing with a bunch of ACLs, however I'm looking for a more manageable solution.

Cisco Firewall :: PIX 525 Anti-Spoofing Attack Protection

Mar 19, 2011

I have multiple questions about the PIX 525 software version 8.0(2) ASDM 6.0 (2)I am a windows network admin that is new to Cisco and routing in general. I have read through the forums and the Cisco documentation, but have not been able to fully understand the topics discussed within.

1. Anti-Spoofing Attack Protection
2. Scanning Threat Detection - Auto Shun
3. NTP Sync Verification
4. QoS implementation5. IOS and ASDM Backup
This option is currently DISSABLED for all interfaces.I know what ip address spoofing is, but what is the functionality of these options specifically? How does it work and should I enable it and for which interfaces? Second Question: Scanning Threat Detection - Auto Shun
I found this option in ASDM under: Configuration --> Firewall --> Threat Detection.Enable Basic Threat Detection and Enable Scanning Threat Detection are both currently ENABLED, but Shun Hosts detected by scanning threat is currently DISABLED. Also, the Networks Excluded from Shun field is empty. I know what the shun command does. I have used it many times when I have been fortunate enough to catch some piece of **** trying to spam my mail server or gain access to it.
What I am asking specifically is how does the Auto Shun work? Should I enable it and what are the potential consequences? Also, what exactly is a scanning attack?
I am not familiar enough with the PIX and with the topics discussed in the document to successfully apply the info within. Plus, I'm not sure it covers the kind of basic, all-inclusive bandwith cap I would like to put in place.
The goal is to cap the maximum internet (outside) bandwidth that inside5 can use to a reasonable percentage while allowing the other interfaces to have the remainder.

How would I go about this implementation? 2. Is there a way to allow inside1 - inside4 to use max bandwidth when there is no traffic on inside5?
I am probably, at least, the third owner of this device and I do not have an account with Cisco nor can my tiny (perhaps non-exsistant given the current economic state) IT budget afford any form of support or software licensing with them.My goal is to backup the IOS and ASDM data in the event that I have to replace the device due to a hardware failure.
I found a file transfer function within ASDM which allowed my to copy the files pix802.bin, asdm-602.bin and tfp from flash to my desktop computer. I also have a copy of the activation key info and my current configuration.
1. Have I backed up all the data/info I would need to restore this software and ASDM to another unit.
2. The activation key screen also has a serial number field. Is this the hardware serial number or is it for the software? and is it tied to this device specifically or can I use it to restore another unit if necessary?
3. Is there anything else I should do or be aware of regarding backup and restore for the PIX?
4. What is the tfp file?

No Internet After Virus

Dec 11, 2011

I'm having is I used to have a virus on my computer, until running a number of scanners to get it off. I'm pretty sure it's clean at this point, but now I've ran into the problem of not getting any internet from my ethernet cord. I've tried plugging in another and it gave me the same problem. I've tried running WinSock hoping it was just a registry problem I could fix, but that didn't seem to work. I also tried running "ipconfig /all" in my command prompt and got this error: [code] I'm running Windows XP Professional, Service Pack 2.I'm at the point where I'm considering just reinstalling Windows, but I figured I might as well ask someone who knows better than I do of a better alternative.

Using Virus Scanner Over The Network?

Sep 22, 2011

using virus scanner over the network and this is related to my workplace. a pc with win xp can share all drives (including c:) over the network with another pc with win xp as well. let's say pc1 and pc2 (both with win xp). i can scan pc2 from pc1 once i hv shared all the drives. but for win vista n 7, i found out that it is not possible to share c:...yes, there are some ways to share it but the entire c: cannot be shared. n i also know that c: cannot be shared entirely due to security purposes. but can i bypass this only for virus scanning purpose? i know many will juz ask me to install the anti virus on the infected pc, but if possible i want to scan it over the network. if i hv to scan 20 PCs at the same time i find it easier to do it from a single pc than to install the anti-virus at every single pc.

Internet Won't Connect After Window 7 Virus

May 18, 2011

Today I got the Win 7 virus on my laptop and did a system restore under safe mode and downloaded malwarebytes via pen drive from another computer and did the full scan and nothing came up. Computer is now showing nonsigns of the virus but Internet is unable to connect to the wireless. My regular virus protection isn't working well either, it won't let me scan my computer and real-time scanning keeps turning off after I set it on.

Does Router Itself Provide Security From Virus

Mar 8, 2011

When one sets up a wireless network, do devices that use the Internet wirelessly benefit from increased security because their connection comes through a router? I thought I heard this from a tech podcast. I don't mean security from hacking, such as having a password, etc. I mean that the router itself gives some security from virus.

No Internet Connection After Removing Virus

Jan 2, 2012

I encountered a similar problem of no internet after virus removal.

a) IE shows "Internet Explorer cannot display the webpage"
b) MSN and Skype do not seem to respond as well
c) My laptop is connected to a router and I'm able to access other PC on the LAN, but not anything requires internet access
d) The LAN icon on the taskbar shows my PC is connected to both the router and the internet (but internet just somehow doesnt work)
e) Proxy option isn't enabled
f) Booted my Win Vista in Safe Mode with Networking, internet doesnt work as well
g) output from ipconfig seems ok; able to ping gateway ip
h) checked the list of network services posted on this thread; they're all started
i) Removed my antivirus program and disabled windows firewall; to no avail as well
j) MSN repair suggests that there's firewall/ dns issue that causes MSN couldnt connect
k) Both wired and wireless connections used to work; but both not working now
l) Other PCs on the LAN are able to connect to internet

Does A Single Router Within Network Block Virus

Jul 6, 2012

We have two network (one have internet access and other doesnt have) within a same office and some pcs are connected to both the network using two NIC. So i am planning to implement a router in between those network and as it implement default routing so we can share all the resources. make both the network secure from virus as one of the network should be worm free. What i personally think that implementing a router will reduce worm replication.

Cannot Connect To Internet After Virus / System Restore?

Apr 23, 2012

I have Windows Vista. So I had a virus that was making it impossible for me to open a web browser without it starting a fake security scan and spamming my screen with multiple browsers. I had no other choice but to do a system restore since I had this problem in the past and a system restore fixed my computer. But, after the system restore, I can connect to the network using a wireless, but when I try to open any browser(firefox/internet explorer) it says internet explorer cannot display the webpage or server not found on firefox. I've tried resetting my internet settings, but no luck. I also don't have an internet security anymore since I was trying to install Kaspersky, but kept having trouble installing it properly.
