block skype 5.1 in my network. This version of skype doesn't need Administrator rights to be installed. In my network there are 2 ways to Internet, one filtered by a PIX 525 ver 6.3(3) and the other by a ASA 5510 ver 8.3(2). No IPS system present on my network.

View 1 Replies View RelatedI just bought an e2500 to replace my WRT54g, hoping that it would fix my call dropping problem. I had tried installing some friend recommended third party firmware on the WRT54g that he said would fix my problem, and with my infinite technological wisdom and experience ended up bricking it.
My problem is that randomly during skype calls with my family back home, I will lose internet connection. It drops the skype call and then I cannot open a web page or anything for about 60 seconds. My internets dead, then it just starts working normally again by itself. I can have anywhere from 60 seconds of connectivity up to 20 minutes or more while skyping. This all happens over a wired connection. Changing the router didn't change a thing, the problem still happens in exactly the same way. I have good bandwidth and all that stuff.Also, I watch netflix on my Xbox 360 over a wireless connection. Sometimes it will just lose connection in the middle of a show. However, the difference is that I can reconnect almost instantly after an interruption on that device. I have fixed the settings on the two different channels according to one of the other post I found in this community, and have not tried those settings out yet. This doesn't worry me as much as the wired connection issues.

View 2 Replies View Relatedis it possible to block outgonig multicast L2 frames on an Ethernet port in outgoing direction on a 2960 Switch?
I tried the "switchport block multicast" command, but the description of this feature relates to only "unknown" multicast!?
But what means "unknown multicast"? Even if activated, I see a lot of multicast traffic going out that port: IGMP, PIM, SSDP, HSRP, OSPF, .. and also pings and VLC streams to multicastaddresses (ip igmp snooping disabled).
I also tried to map a "mac access-list" to that port, but the "mac access-group" interface command is restricted to only incoming traffic.
Reason: we assume, that there are a couple of specific enddevices, that might react strange to some multicast. Therefor we would like to block outgoing multicast on that specific ports.
I tested it on a 2960 12.2(53)SE2

View 3 Replies View Relatedhow to go about setting up the ASA to block any SMTP traffic outbound except for our Exchange Server. This is in relationship to a SpamBot issue that blacklisted us. I have an ASA 5510 running version 6.2(5) / 8.2(2) with three ports. DMZ, Inside and the Outside interface. Up till today, I only needed to block outside traffic to our internal network which I used the ASDM to configure a rule on the outside interface for an incoming rule. I am assuming I need to create an outgoing rule on the outside interface; however, just to make sure I understand the terminology/traffic flow, I created the rule with my computer as the source (192.168.0.131) with ALL destination and the service as HTTP. My logic, which seems to fail here, is that any traffic from my computer going outbound would be blocked; however I am still able to browse... That said, if I were to change the source as the Exchange server and the Service Type to SMTP, it would not actually block traffic and therefore not solve our problem. I even gone as far as permitting traffic from my computer, expanding the hit counter and I see no hits. So I am no doubt doing this wrong. What I do know, is when I first created the rule, a second rule was automatically created (Implicit rule) that deny all sources and blocked all HTTP traffic until I changed it to Permit?
View 2 Replies View RelatedI'm using an ASA5505 (8.4(1)) and would like to block port 80 on a specific host in the LAN so machines in other remote LANs connected via VPN can't access this port on the host. Devices in the local LAN should have access to this port on the host. Here are the commands I'm using:
-access-list block_port extended deny tcp any host 10.20.10.20 eq 80
-access-list block_port extended permit ip any any
-access-group block_port out interface inside
These commands are not working as I would expect them to. When I browse to http://10.20.10.20 from a remote machine over the VPN tunnel I am able to access the host web server.
Setup firewall rules that will block all inbound Internet access to the web server except port 443, Setup firewall rules that will block all communication between the two internal networks, except ports 7000 and 1702

One of the vlans, has a vonage linksys box attached to it with a UK number attached. From time to time telemarketers call at 03:00 in the morning, this as I'm sure you can imagine is not much fun. The linksys box gets 192.168.3.3 as it's ip.The switch is connected to a non cisco router at 192.168.0.1

no switchport
ip address 192.168.0.2 255.255.255.0
I was thinking a time based access list would work best I have tried several variations but the phone still rings. I have tried access-list 1 deny host 192.168.3.3 permit ..... and more extensive lists but the phone still rings. I have not applied the time-range yet, so that's not the problem.I have applied the list to the vlan interface and to fa0/24 but it's not working.

View 1 Replies View RelatedBought 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.
