Aug 22, 2011

I can connect to Internet perfectly fine.  I can even VPN back into my office.  However, once connected via VPN and I launch my Outlook Client, I'm not able to connect to get emails.  When I run a "netstat -a", I get my "SYN_SENT" to all my office domain controllers and exchange servers.However, if I connected via my Starhub USB Broadband dongle, everything works perfectly fine.What settings do I need to do on my router?  I tried port forwarding and application rules but none worked.

Cisco WAN :: 2960 - Block Outgoing Multicast On L2 Port?

Aug 2, 2012

is 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

Cisco Firewall :: ASA 5510 - Setting Up SMTP Port Block?

Mar 5, 2012

how 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?

Cisco Firewall :: 5505 Block Port 80 On A Specific Host In LAN

Apr 22, 2012

I'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.

Cisco Switching/Routing :: 3550 / Access List - Block One Ip Or Port

Jan 9, 2012

I have a layer 3 switch, 3550.I have several vlans on there just for playing around with. 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
 
interface FastEthernet0/24
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.

Cannot Access Local App Server On Port 8080

May 23, 2011

I'm trying to develop and test a website from my iPad. I have my laptop and iPad on same local network, 192.168.1.xThey can see each other over network and I can access the page:192.168.1.105:80 (my laptops local web server) from both iPad and laptop. However the application server runs on port 8080 and I cannot access this from either device/machine. the router's firewall is playing a role, and I have no software firewall running on laptop that I'm aware of (turned off windows 7 firewall).localhost:8080/myWebSite or 127.0.0.1 also works on port 8080.The only combo that does not work is 192.168.1.105 with port 8080. I need this so the iPad can hit the site so I can test locally while developing.

Apr 26, 2011

I have a 4-port Zyxel P334U with WLAN, and I would want to set it up so that besides normal WAN, each connected computer also has access to the other local computers. I've tried setting it up before, but haven't managed to get it working, so I gave up.I have DHCP set up, beginning at 192.168.1.16. WAN and ISP DHCP works, so each computer has a local IP (192.168.1.x) and a remote IP given by the ISP.

the question is why is this showing that Gig0/3 is being used twice to  connect to two different devices.  I have verified there is no hub  connected to this port and in fact Switch3 is not connected to Switch1  at all yet it still shows up in the CDP table.
 
I have cleared the CDP table on every device at this location and still get the same results.

Linksys Wireless Router :: Wrt54gs / Setup Local DNS Server To Manage Small Office Local-only Domain Names?

Apr 22, 2012

i'm trying to setup a local DNS server to manage small office local-only domain names for our servers. i have the DNS working properly (resolving local machines and using the ISP dns if it can't). so i put the DNS server ip into the "Static DNS 1" field of the router settings. the other 2 static dns fields are empty.the problem is that the router is still using the ISP dns server as the primary and my local dns server as the secondary. i verify this in two places. first, if i go to the "status" tab, DNS 1 shows the ISP server while DNS 2 shows my local DNS server. secondly, if i connect to the wireless device with a linux-based machine, the /etc/resolv.conf file shows the nameserver ips in the same incorrect order.
