View 3 RepliesAs we are unable to control downloads and P2P use in our network, we are thinking to block all ports except 80 and 443 in our router so that they can only browse and use them only for office use. They should also be able to use messengers like skype, YM, MSN and also download any attachments in email.I wonder if we implement this, will it going to work or will there be any problem in accessing normal websites too? I know to control downloads there are many premium hardware and software firewalls out there but we don't want to invest any thing for now.I also know PTP clients can still use 80 and 443 ports to connect but it will need user to change manually port so it's fine with us.
View 1 Replies View RelatedI am running two ASA 5520 routers synched up with eachother. I had a massive connectivity issue this weekend that I am investigating. Now I have figured out how to get the live logging but I need to know how to get the old logs from my router.Also I am looking to set up a log dump that could happen daily or perhaps weekly.
View 1 Replies View RelatedI've enabled antispoof on all interfaces on asa 5510.If you start a traceroute to a network on the default route, everything works, since replies comes to an interface with route 0.0.0.0/0 defined.If you start a tracer route to a network that is NOT on the default route (let's assume coporate MPLS), you only get response from first carrier router, the other are discarded because of anti spoof violation.
I have ICMP inspection and icmp-error inspection enabled.
it says no network found. It worked fine but not now.

View 13 Replies View RelatedFor the past week I've had a problem browsing the internet. Now, at first, this only happened starting at around 3 am central time and ending at about 6 am when I could browse the internet properly. As the days went forth, however, it began happening earlier at around 12 am. What would happen is this: would be on the internet browsing sites and whatnot. All of a sudden (As I'm loading a new page) I would get the "Address not found" error as if I'm not connected to the internet. I could try to reload any other page on my session,but sometimes it would halfway load (ei:not loading pictures, ect.) and other times I would get Address not found. This would go for about a 4 hour time period. After that, everything would be back to normal and I could go back on my session.
Now, I'm on my laptop via a router that is in my house. We also have a desktop computer, but I noticed this problem happening on my laptop first. When it first happened, it was only on my laptop. I had internet connection and could browse it endlessly on my desktop. As the days went on, however, my desktop started having the same problem connecting to the internet (I still noticed the problem on my laptop first and then I would go see if the desktop had it too).When this first happened, I was thinking my laptop wasn't connecting to my router. Instinctively, I reset the router to no avail. I also opened up IE (I don't use it much because it's just too slow) and tried to diagnose the problem using that. When I did this, it was giving me DNS as the problem of me not connecting to the internet. I am not a network admin so I don't know that much about DNS. I also used IE to diagnose the problem on the following days, but after the first time it only gave me a "You aren't connected to the internet" solution. Since then, I've been running a barrage of anti virus, rootkit, ect. just because I can and I haven't done it in a long time. I didn't find anything unusual in all the reports so I'm still not sure what the problem is.
i cannot find any connections!! i can with a eithernet cable but i want wireless!

I just downgraded from vista to XP on my Compaq pc that a friend gave to me. The hard drives were loaded with junk so i decided to do a fresh install with my Windows XP cd. Everything looks like its working great except it seems as if ive lost all drivers necessary to connect to the internet. Pretty much the computer can't even tell that theres a network adapter installed.

View 1 Replies View Relatedjust noticed today, that there's a FW ver.4.13 for Rev.D, which I uploaded into the router too. Captcha is now gone (I read it was flawed anyway), and no option to turn it back on (I'd do anyway).So I'm looking for the older firmware that I was using for a year or so, which was 4.11. I found it and downgraded to it (actually, this was on another DIR615 rev.D), and guess what? No catpcha in that either!As far as I remember, I was using 4.11-B04 (but not sure, really), whatever it means, and now I only find 4.11-B02 everywhere.Is it possible that those FWs with buggy captcha have been removed from FTP servers worldwide?
View 5 Replies View RelatedI am trying to install the WLAN driver for Dell Dimension 9200C desktop computer running Windows XP but I keep getting the error that no compatible hardware was found. I've gone to the appropriate Dell Drivers site for the computer's model and I'm 99% sure I downloaded the correct software for WLAN: Dell Wireless 1395 WLAN MiniCard. After going to Device Manager and looking under "Network Adapters", there is no Dell WLAN card at all (direct ethernet connection for internet works). Is it possible that the computer cannot find the WLAN network card, which prevents me from installing the driver software, even though it exists? If so, what can I do? If not, I guess I'll go buy a USB network adapter.
View 2 Replies View RelatedI am having a major issue trying to connect my Windows 7 HP Netbook to my Xbox 360 over either Twonky/Serviio or Windows Media Centre. The Xbox just isn't picking up my computer, my homegroup recognises the Xbox and it is 'Allowed' to share media, but when I test my PC connection within the Xbox dashboard, it fails to connect to PC. My network is wireless.The strange thing is I have TwonkyServer Mobile running on my Android phone and that was found by my Xbox immediately with no need to change settings or search for devices. It streams media just fine from my phone. This leaves me thinking that it is an issue with my PC as opposed to my router, I have double checked my router settings (Sagem 2304), UPnP is showing as enabled, I've reset and unchecked/rechecked the UPnP but still not working.
My TwonkyMobileServer is also unable to find my PC server although I have been able to find my MobileServer in Windows Media Player and stream media from my phone.Windows Firewall has been disabled, I've also Uninstalled my antivirus software, Avast and AVG, although AVG doesn't seem to want to disappear that easily and is still lurking in my System Tray telling me i've 'Lost protection'...Norton Internet Security is also lurking around which is odd, I can not recall installing it! It doesn't seem to be a fully installed version and doesn't seem to want to be uninstalled. Could these AV software and supposed Internet Security software be holding me back?This leaves me thinking that my PC is holding back my Network. Is there any thing I haven't thought of? Would it be the Anti-virus leftovers ruining my streaming dreams??

View 1 Replies View RelatedI'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.

Make sure the wireless switch on your computer is on. To see an updates list, click "Refresh network list."'. The strange thing is that I'm connected to the wireless network on my phone so it must be in range.I'm using a Samsung laptop (Not sure of the model) that is running on windows xp.It doesn't have wireless connectivity built in so I am connected to the wireless using an 802.11 USB Wireless LAN Card network adaptor that is made by Ralink Technology, which is working properly according to the device status.

View 2 Replies View RelatedI tried to forward a new port on my Actiontec V1000H router. I was able to sign in without incident, but the moment I tried to begin navigating within pages, I would be greeted with a red screen reading '400 Bad Request - No request found' roughly 60% of the time. Usually refreshing the page a number of times would allow me to proceed, but because the Telus software for the V1000H cycles through so many pages when applying a new forwarded port to the firewall, it's almost statistically impossible to make it through.I have no issues with internet connectivity, and having this port forwarded isn't critical, but this problem is a real nuisance as it turns changing any router settings into a long, tedious, and sometimes downright impossible chore.
