Cisco :: Range Of Ports In Packet Tracer

Oct 27, 2012

I'm preparing myself for CCNA exam and i started doing a lot of different examples. I've got problem with Packet Tracer when i'm trying to apply some security settings for the range of switch ports in default VLAN 1. I might just demonstrate my commands so it will be easier do understand.

Can't Ping Between Routers (Packet Tracer)

Mar 6, 2011

I'm trying to set up a network comprised of three LANs connected by serial. As this is a small part of an assignment I've been instructed to subnet into /26 and to use /30 subnets for my serial connections.At the moment I can ping between devices on each of the LANs but I can't ping between routers at all. Embarrassingly I'm not sure why, I think it may be something I've missed on setting up the serial links as I have set routers up fine before using other connection types.

Cisco :: Simulate An ISA Server In Packet Tracer?

Jan 21, 2013

I'm an IT student and I've been assigned with homework simulating a network including an ISA server and some clients in Packet Tracer but I can't find anything which can be configured like an ISA (Internet Security and Acceleration) server(this is kind of Microsoft's technology as I know) in Packet Tracer, the generic Server from the devices box has only some basic services such as HTTP, DHCP, DNS, FTP, AAA, ... but none of anything related to ISA, all the servers in Packet Tracer have only 1 interface whereas the ISA server (as far as I know) should have at least two interfaces, and there is also no CLI supported for those servers so I think I can't simulate ISA server in Packet Tracer, can I?

Cisco :: VLANs Route Outside Of Network Packet Tracer

May 30, 2012

I am unable to get traffic from any VLAN to communicate outside of the router, as well as get any traffic from outside of the router to communicate with any device on either VLAN. I am able to ping the router from each device on each VLAN, and vice versa. However, the traffic seems to die at the router, and I cannot figure out why. I know it's probably a small, easy fix, but I cannot seem to find any kind of documentation on it.

Is it an access list that is blocking the traffice or VPN setup.

Cisco Firewall :: 5550 ASA (8.3) - Packet Tracer / Multi-Context Classification

Nov 22, 2011

I've been using packet-tracer for some time on and off with mixed results.
 
I'm running a multi context firewall with over 10 of the contexts sharing the same outside interface / network. All interfaces obviously have valid, unique IPs and also unique MAC addresses as mac-address auto is enabled in the system context.
 
This is an ASA 5550 running 8.3(2.10) interim so includes the fix for the well known packet-tracer classication failed bug.
 
So in theory, with firewall contexts on a shared interface the ASA should use the firewall MAC address to classify incoming traffic to the correct firewall and as far as I am aware, only fall back on using NAT to classify if the interface MACs are the same. In reality on my platform this doesn't seem to be happening and the classifier is using NAT to determine the destination context. I'm seeing this with live traffic (i.e. not generated by packet-tracer) in logs and can prove it by disabling certain NAT rules (there is some overlap with the IP addressing behind each firewall).
 
My question regarding packet tracer is this - in the above scenario with a shared outside interface, does packet tracer ALWAYS use NAT to determine the destination context? Or does packet tracer look up the MAC address of the ingress interface according to what context you are running packet tracer from? It appears that packet-tracer is using NAT in my case which could be just symptomatic of the potential bug I've described above rather than by design.

Cisco ASA 5505 Simple PAT - Packet-tracer Can't Look At Any External Devices While Running

Sep 16, 2012

here, am used to the RouterSwitch CLI but been asked to set up an ASA 5505 8.4.Quite simply I am trying to at least test out a static PAT from an external source to an internal server in a test environment and no matter whether I set it up as an auto-nat or a twice-nat whenever I run a packet tracer I end up with the same error. This is the packet-tracer I am running-packet-trace input outside tcp 80.80.80.80 3389 10.240.0.10 3389
 
Phase: 5
Type: NAT
Subtype: rpf-check
Result: DROP
Config:nat (inside,outside) source static server publicIP service RDP RDP
Additional Information:
 
[code]....
 
Now I have a couple of questions initially. I have made the presumption that packet-tracer does not look at any external devices while running - as in as long as the ports are up it doesn't matter what is on the end of them for testing purposes? Is there anything I am missing?I have this morning wiped the config and have simply set up the adapters, a default route and twice nat and am not sure why I keep getting the error. I am sure it is something very simple and I'm being a massive donut!

Cisco Switching/Routing :: 3560 Topology In Packet Tracer Related To Etherchannel Configuration

May 23, 2012

i have made a topology in packet tracer related to etherchannel configuration.i am using 2 3560 switches and 1 2950 switch. Now what i want is to bundle up the redundant links between these 3 switches. The links fa0/1-3 between 2950_1 and 3560_1 switches have been bundled up but when i try to bundle the links fa0/4-6 of 3560_1 to fa0/4-6 of 3560_2 it wont work. i am using channel-group 1 mode desirable between the 3560 switches. secondly if i want to assign ip to port channels then it has to be of same subnet between 2 3560 switches right and it must be same between 2950_1 and 3560_1. But these 2 subnets should be different from one another.

Cisco Firewall :: ASA 5505 - PAT Range Of Ports

May 31, 2011

I've an ASA 5505 as my gateway for my internet at home. I've one public IP, so I use Port Address translatetion for my internal clients.
 
Now i wanna setup a FTP server, on a internal client. I will use Filezilla FTP server. I'm running the FTP server in passive mode, since the FTP server would be behind my ASA firewall/nat device.
 
I need 50 ports for the passive mode to be running.
 
I will use port range 50000-50050. I can easy make a firewall rule (access-list) that permit that port range.
 
But how do I PAT(NAT) a port-range on the ASA device? I can only figure out how to NAT one port at the time.

Cisco Firewall :: Port Forwarding A Range Of Ports (PIX 6.3)

Dec 5, 2012

I have a network with multiple servers behind a PIX with 6.3 on it. I have one public IP address, and I'm using NAT. I'm currently trying to port my Exchange server to a cloud host, and the vendor is requiring I open up a wide range of ports for MAPI, basically ports 1024 on. What would be the command to forward all of the trafic cominto/from that broad range? if I could simply route all trafic to and from their two IP addresses to my email server, that would accomplish the same end goal.

Cisco Routers :: Forward Range Of Ports With RV180W?

Oct 14, 2012

I am new to the RV180W. I am running the most recent firmware--version 1.0.1.9.
 
I am having trouble getting FTP to work with my QNAP NAS.
 
QNAP indicates that I should forward ports 55536-56559 to my NAS. I created a custom service to accomplish this, and then, under port forwarding, I selected the service and forwarded it to the private IP that corresponds with the NAS.
 
However, the port forwarding configuration only allows me to specify *ONE* internal port. With other routers I have always specified the same private port *RANGE* that corresponds with the public ports that I have opened up.

Cisco Routers :: How To Open Range Of Ports In RV016

Jun 28, 2012

I am trying to add a couple VOIP phone units that do not have their own router.  They are designed to run of the existing router and have three ranges of UDP ports opened up.  They also do not advise using internal (private) statics on the phones. So what they are asking for is three different ranges of UDP ports to be opened up to all behind the router?

I cannot figure out how to do this (or if it is possible) with a RV016.

Cisco Firewall :: 5505 - Forward Range Of Ports In 8.4?

Mar 11, 2011

I have an ASA 5505 running 8.4(1), and I'm configuring it with ASDM 6.4(1).  The outside interface is configured with a single static address.  I have a few services port forwarded sucessfully to three different servers on the inside network.
 
I need to make a media proxy on a SIP server available to the outside.  It requires a large range of forwarded UDP ports for the media channels.
 
I tried adding a network object NAT rule like the others I'm already using to forward HTTP and RDP.  I entered a range of ports for the real port and the mapped port using the syntax 60000-60999.  ASDM accepted it, but the NAT rule list displays "Any" in the service column.  When I apply the change, I get the following error:
 
nat (inside,outside) static interface service tcp 60000-60999 60000-60999
                                      ^
ERROR: % Invalid input detected at '^' marker.
 
How do I forward a large range of UDP ports from the outside interface to a single server on my inside network?  I'd like to use ASDM, but I can switch to the CLI if that works better.

PC Sending Packets To Random IP's From A Range Of Ports?

Aug 27, 2012

So this is somewhat of a strange issue. I have a program called PeerGuardian 2 and it allows me to simplistically see the packets being sent to and from devices on my home network. It's showing that my computer is sending packets to random IP addresses, some of them reoccur, on a massive range of ports all going in order.

(example)
From 192.168.1.253:6812 - To 74.120.148.2:80
From 192.168.1.253:6813 - To 74.120.148.2:80
From 192.168.1.253:6814 - To 74.120.148.2:80
From 192.168.1.253:6815 - To 74.120.148.2:80
From 192.168.1.253:6816 - To 74.120.148.2:80
From 192.168.1.253:6817 - To 74.120.148.2:80

This happens in spurts and it usually sends 20-40 to varying IP addresses in a matter of a few seconds. I asked my ISP if they understood what this was and it stumped the technician I spoke with. I also have run multiple virus/malware scans and everything comes up clean.
