Aug 22, 2011I 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.

Aug 2, 2012is 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 RelatedCisco Firewall :: ASA 5510 - Setting Up SMTP Port Block?
Mar 5, 2012how 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?

Apr 22, 2012I'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.

Jan 9, 2012I 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.

Oct 31, 2012I am learning to write ACL's along with a billion other Cisco things. The internet is not clear on how to do this exactly. At least in my research.
I have two host on the same subnet and I want to block all except RDP TCP port 3389 from one host to another.
I want to apply that Access-group to a switchport interface on my 3750 that belongs to the computer I want to protect from the other.
Host A: 10.1.1.10/24 -- I need to block all TCP and UDP traffic except for port 3389tcp
Host B: 10.1.1.60/24 -- I need to allow only TCP port 3389 from Host A to this one.
This is on the same switch so I can use an extended ACL like 101 or whatever.
This is almost starting to make sense to me but im still weak on extended ACL. I got basics down pretty well.
