Cisco :: Why Are TCP / UDP Ports 135-139 Sometimes Blocked By ISP

Jan 30, 2011

I have seen several cases where ISP's block traffic on both UDP and TCP ports 135-139 even in core firewalls. Port 135 should be Microsoft EPMAP service and ports 136-139 should be NetBIOS services. However, why do ISP's sometimes block traffic on those ports?

Ports On PC Appear To Be Blocked?

Dec 16, 2011

On my home network I have two computers:

PC#1 - my main computer

PC#2 - my laptop

Each of these has Windows 7, Avast! Anti-VirusToday I was working on a website on PC#1. When I attempted to upload the files via FTP, the connection failed repeatedly. When I went onto PC#2 it worked first time.I also tried to launch World of Warcraft on PC#1, this failed. It worked first time on PC#2.Websites work fine, so port 80 appears to be okay.I have reset my router to factory settings. ipconfig /release /renear /flushdns all made no difference.

What Will Happen If All Ports Are Blocked Except 80 And 443 In Router

Jan 5, 2013

As 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.

Security / Firewalls :: All Ports Blocked Even With DMZ And Firewall Down

Oct 16, 2012

I've been trying to open ports 5800 and 5900 for UltraVNC and checking them with online port checkers, but they are always listed as closed. I've even tried taking town windows firewall, my router firewall (although as soon as I disable and apply, it automatically switches back to enabled again), and also DMZ'ing my router. I wonder if it might have something to do with my new modem, but in the config page for that, the advanced settings are locked out. the modem is an arris TM722G, and the router is a linksys wrt-54G with DDWRT firmware.

I'm running windows 7 x64 and using a static local IP, I want to be able to use DynDNS to connect to UltraVNC.

Cisco Firewall :: ASA 5505 / Use The Ethernet Ports As Pure Physical Layer 3 Ports

Jun 9, 2013

We have an ASA 5505. 5505 comes with two default vlans 1&2 with each of them marked as inside & outside respectively.My query is , if i do not want to use vlans on 5505 and only want to use the Ethernet ports as pure physical layer 3 ports, is it possible?i.e. i want to assign a layer 3 ip address on eth0/0 and eth0/1 and make them as the inside & outside interfaces rather than vlans. is it possible to do away with vlans in 5505 & will it work otherwise?

Cisco Firewall :: ASA5555-X - Spare Ports Into Access Ports?

May 14, 2013

Is there a way to associate spare firewall ports with another port that is being used..For example...int gi 0/2 is being used currently for my web dmz. Its ip is 192.168.10.1..Is there a way for me to associate gi 0/3 with the same layer 2 as gi 0/2 ?
 
In my webdmz I use 2 ACE 4710 proxys in FT mode. I used a layer 2 switch to connect firewall and proxys together.
 
I would like to eliminate this switch if possible..and connect both 4710's (layer 2) direct to firewall.If I could make gi0/2 - 4 part of the same vlan, then I would be good to go.

Port 80 Is Blocked By ISP?

Jan 11, 2013

setup a web server at home but just found out yesterday that my ISP is blocking port 80 on my network and they won't open it unless i upgrade my internet service... which i am not sure if there is any other way get this solved. If I port forward my site at my web server to (let say) 85, when someone type [URL] (with 80 by default), will it be somewhat in the cloud or some server to NAT 80 to 85 at my site? In short, can one type [URL] instead of [URL] ?

401 The Web Site Is Blocked By The Administrator

Feb 6, 2011

For some time, I cannot access some websites. It gives me a 401 the web site is blocked by the administrator. I use a d-link router and my brother is the administrator. He told me he hasn't blocked anything. We tried to reset the router but it still gives me the 401 problem.I think it isn't a router problem. I have tried using my laptop and tried to access some sites. It still gives me the error so i dont think it's a computer related problem. I have tried to ping it. It still doesn't work. I have also tried to erase all the cookies and cache. The problem is still there. How can I fix this? My operating system is Windows XP Professional version 2002 service pack 2.

Blocked From Internet Access?

Mar 28, 2013

I have a brother who frequently blocks my internet access, and he does it while maintaining his own connection so he's not unplugging the router or anything. He also blocks it from his own computer, meaning he doesn't take out my wireless card or anything like that. I was wondering how to counter this and get my internet back whenever he blocks it, or prevent it.

Cisco LAN :: 3750G - DHCP Blocked By VLAN

Jan 22, 2012

We have a server that we remove from the rack. The only role it has is to give out DHCP on the wireless network. I tried enabling  the built in DHCP server on  the Airespace 4112, though a Catalyst 3750G, but I dont get an address when I'm connected to the wireless network even though the range is enabled. If I set an static IP on my wireless card I can access the network. I also tried enabling DHCP on a Sonicwall that is connected to the Catalyst 3750G.
 
 Do I need to link the DHCP scope to the wireless network? Is there anything on the switch that would be blocking DCHP since it on a VLAN? I have the last four ports in a VLAN for the AP's and the internet connection to the Sonciwall.
