Cisco Firewall :: 2911 - IOS Content Filtering Using Trend Micro

Apr 26, 2012

I have IOS content filtering using the Trend Micro subscription service working on a 2911 running 15.1.(3)T3 with the security license option and a 30 day demo Trend subscription. Once I figured out that the content filtering for Trend appears to be completely broken in 15.2 (even using docs for 15.2) I went back to 15.1 and it works great.
Everything seems great so far except I would like to have a more 'fancy' or custom blocked page where a user can have a couple links to either go to the trend micro reporting page [URL] or some other page, and maybe some branding so they know the page is coming from our network and is not some fake security thing or phishing attempt or whatever.
I know I can use the 'parameter-map type urlf policy trend ' section to do a tiny bit of customization of the text that appears on the default blocked page display and there is an option for it to go to a simple redirect instead ('block-page redirect -url') but how to do more with either the built in page or the redirect- url to keep the information of what page the user was trying to access and why it was blocked (category etc.) while adding more features.
Oh, one last thing, this doesn't support any kind of 'user override' or anything like that does it? So that a network can have a filter applied but an admin could override the filtering to allow temporary access to something?

Establish A Network Between Two Computers With Windows 7 And XP?

Jan 3, 2012

I have spent a couple of hours to find an easy way to connect my old laptop with Windows XP with my new notebook running Windows 7. I have obtained a little bit of background information but am lost in the WWW.

I now know that I would need a special USB cable or a cross-over ethernet cable for a wired connection. As I don't have either at the moment I looked into creating a ad-hoc WiFi network between both computers. I found instructions how to set one up under Win XP and another one for Win 7 but I have found no information whether and how I can actually connect both. I reckon that I only need to set one up on one computer and then would have to somehow make the other computer detect and join that network.

Cisco Firewall :: ASA5520 -CSC SSM (Trend Micro) / Browse Internet Slow

Nov 10, 2012

I recently deployed this module on Cisco ASA 5520 (v8.2.5) at a client's place. I'm having problems. Even if there's 1 user, browsing Internet is super slow. If I were to bypass the CSC SSM (for 10 users) module by removing the "service-policy TEST interface inside" command, browsing Internet is very fast. Based on my troubleshooting, if I were to disable Web Filtering, Web Reputation and URL Blocking & Filtering, and leave all other services enabled, then the browsing is fast. how come I enable the 3 services stated above and browsing the Internet is slow, even for 1 LAN user. I don't have any thing configured under these 3 services. Just by enabling the services alone, it's already slow. It doesn't make sense for Cisco to sell such an expensive product and it can't even handle 1 user with no settings but services enabled.

Cisco WAN :: 2960 Buffers (drops / Packet Loss Due To Micro-bursts)?

Dec 21, 2011

Have a pair of 2960's in a stack, one port(trunk) connects to another DC and we are seeing ~5% packet-loss and large output drops to this DC.

#sh interfaces gigabitEthernet 1/0/17 counters errors

Port        Align-Err     FCS-Err    Xmit-Err     Rcv-Err  UnderSize  OutDiscards

  Hardware is Gigabit Ethernet, address is a0cf.5b87.ec11 (bia a0cf.5b87.ec11)

As you can see, 30sec rate isnt excessive, but as the drops are outdiscards it would appear we are getting hit by the small buffers/microburst issue.

Home Network :: How To Establish Wireless Connection Between Two Houses

Dec 26, 2011

I need to get the internet from my uncle and aunt's house to my grandma's house next door. I don't know exact feet or anything like that yet but I will get it measured off. My grandma's kids got her a laptop for Christmas but she doesn't have the internet or would be wanting to spend money on it a month since she already says she will not be able to use the computer, but I said we would just somehow get the internet from next door. I don't know off the top of my head but my aunts computer is an older Dell, early P4 computer with xp on it. It's slow but it does work so that is the computer. The router is some sort of D-link with one antenna on it and I'm pretty sure it's probably a G-router(2.4ghz) and not a N-router, but can get that info later too! They currently use Time Warner Cable Roadrunner Turbo for their internet. Both places are well built brick houses and at least 200-300 feet apart. I checked yesterday and the computer was able to pick up the signal in my grandma's house on the end that was closest to my aunts house. It was showing 2 bars but it wasn't extremely fast and that room had a bigger window in it probably allowing some of the signal in? If you moved from that point of the house though and tried to go to the other end, the signal was lost. The router in my aunt's house is one room away from the end of the house that is closest to my grandma's so it could be moved closer but I don't think that will fix the signal enough to do what I need it to do.

On-board NIC Card Stopped Working?

Mar 3, 2013

I have a toshiba satellite laptop (windows 7) with wireless on-board and an ethernet cable port. Up until last night, both worked flawlessly since I bought the computer a few years ago.

Now, the wireless still works in three different locations I have tried (i.e. three different networks), but the ethernet cable will not work. I thought it was the ethernet connection on the mobo at first, but then after acquiring a USB-NIC connection, I found I had the exact same problem... I can't connect to my router or even direct to the DSL modem using a ethernet cable. I know my system is good since all my other computers (7) work with wired connections, and my laptop doesn't work on other cables on which other computers do. Essentially, it appears that my computer has lost the ability to get an i.p. address using an ethernet cable of any kind. Both the onboard card and the usb-nic cable tell me they are 'working correctly' in the systems/devices/network adapters section. I have tried disabling one while trying the other. I have tried disabling the wireless while trying either, and still nothing.

Motorola SURF Board Gateway SBG6580

Oct 2, 2012

Since the new cable company won't let me use my SB6141, I need to pick up a new cable modem. One that works with Oceanic TWC is the new SBG6580. It has wireless built-in; however, I don't want to use it. Is it possible to use this modem and leave the wireless off? Or does the wireless automatically turn-on whenever the modem is on? With all that said, is the built-in wireless any good? I recently purchased an ASUS RT-56 and would prefer using it to some built-in system.

ASUS RT-N66U / Best Router With On-board IPSec VPN Server?

Jan 7, 2013

I'm currently in the market for a new router that supports remote IPSec VPN access to my home network. The router must support wireless (latest "n" standard is a plus) and must have gigabit links for LAN at least. I have been considering the following two routers but neither has an IPSec VPN server built in to the router OS:

MikroTik RB2011UAS-2HnD-IN

As far as I can tell they both have PPTP server functionality and only IPSec pass-through. I would like a router that has the server ability built in to the OS so I won't have to run an additional system behind my network edge. I can also look into any small to medium size business routers, just as long as it supports a majority of the same features of the two routers I have listed for comparison.

Network Controller Drivers Are Not Found

Oct 29, 2011

I've got a Philips MT1800, Intel Core 2 Duo package. My network adapters are recognised (1394 Net Adapter, Intel Pro/1000 PM Network Connection), but in unknown Devices the 'Network Controller' drivers are not found (there was a Ralink RT2500 slot before, I'm assuming this is the missing driver??). EVEREST Home Edition recognises a Ralink RT2500 802.11g Wireless Network Adapter (PCI), and my PC finds new hardware on reboot, but it cannot find drivers at all. I've tried a few methods, such as Driver Detective etc. but don't have the original restore CD any more, so don't want to tamper with any other "out of date" drivers. I am not in a situation where I can order a restore CD, so I'm hesitant to System Restore in case something else becomes unresolvable.

Everything was working fine, I was able to make everything work fine. Then yesterday morning I started up my computer and it was not connected to the internet. My ethernet was plugged in and everything was as it should be. I went in to device manager and noticed that my realtek network controller was not in the device list under network adapters. I then tried to reinstall my LAN drivers from ASUS (my motherboard) which is how I got it to work in the first place. However, this time when it "finishes" installing an error pops up and says "The realtek Network Controller was not found. If deep sleep mode is enabled Please plug the cable."
