Jan 24, 2012I need to permit the connection from outside to inside in a 2911 Cisco router, only from an Public IP Address (suppose 1.1.1.1) to some local private IPs.
I have one question:
Using the command:
ip nat inside source static tcp <local ip> <port> <global ip> <port>
The "global IP" can be the Public IP from where the connection starts (in this case 1.1.1.1)? or it must be the Public IP assigned the the Router interface connected to the Public Network.

Feb 5, 2013I am trying to connect a Control network that can not have access to the Internet, or any other network for that matter, to my Admin network so that I can retrieve trend data about the plant that goes into a database. Right now the process is print information, hand jam into excel spreadsheet, print again, and hand jam into another excel spreadsheet on the other network. Reports are printed automatically once a day, but would like a simplified way of getting data from one network to the other without having to re-enter data several times. Current policies stipulate no USB drives connected to Control systems. Even if we could loosen that, personnel needed to transfer data is not available and going to each individual machine would take more time than current system.Now that background is laid, I have two 2911 ISR routers with EIGRP configured, each with a 4 port EHWIC card. The 3 L3 ports on the router are setup as follows: interface G0/1 to the internet, interface G0/2 to a wireless back haul, and interface G0/0 for IT network. I then have 3 VLANs setup on the EHWICs for our Admin network. We will move the IT network to a VLAN on the remaining EHWIC port and connect the two 2911's through the G0/0 interface. I am going to have one computer on my Administration network dedicated to receiving the information and have a program that will take that data and import it to a database. I need to allow only that computer to receive traffic from the Control network and I need no traffic to flow back into the Control network. In other words I will transmit data from the control network to the admin computer using one protocol (TFTP more than likely) and block any other traffic coming out of and going into the Control network.

View 2 Replies View RelatedCisco WAN :: 2960 - Block Outgoing Multicast On L2 Port?
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 4 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?

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