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?
i'm on the CCNA 4 accessing the WAN part for the Cisco Academy. I'm trying to do a packet tracer 8.6.1 and I'm stuck. I'm looking for the answer so I can figure out what I'm missing.
having some issues. My basic VOIP network I can get to work no problem uner Vlan 1. But when I try tomake multiple basic networks to connect and put them in to diffrent Vlans such as Vlan 2, 3, 4 and conect them the phones now say configuering IP.
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.
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.
I am trying to test PIM SM mode between some 2811 routers built up in my packet tracer 5.3.3 .But surprisingly PIM option is not coming in the interface mode .Even IP multicast option is not shown in global config mode.
I have been playing around with Packet Tracer trying to understand EIGRP and to put it into practice. Well im not doing so well, I cant get the routers to form an adjacency therefore nothing is pinging outside of the routers. [URL]
I'm trying to create a silent, scripted install of Cisco Packet Tracer 5.33. At the end of the install there is a box that comes up about Packet Tracer Skills Based Assessment (PTSBA). Is there a way to supress this dialogue box? I'm using "PacketTracer533_setup.exe" /sp- /verysilent /norestart" with no luck.
have 2 routers connected in cluster ith serial dte link. screenis locked. I need to draw a topology of Internet cluster, but i don't know how to discover whats is in it, because i don't have set ip
I have a project about ISP in packet tracer,I want to know how to make firewall configuration and steps I don't know how to use firewall in packet tracer at all.
using packet tracer, how can i find dns server ip address and i am having trouble pinging the desktops and server that i manually assigned the ip addresses to
I am using packet tracer 5.3 version and I am trying to configure IGRP on it but it doesn't show me igrp under routing protocol selection.Router number is 2621XM.IOS version is 12.2.learn the configuration of IGRP.
I'm student from IT school and i have a school project but i have a problem on packet tracer.In a vlan, i must block the communication between computers in it but i dont know how i must do that.Effectively, it's about 250 computers in this VLAN but each computer can't caommunicate between us.
Asking about Packet Tracer. I currently use packet tracer 5.3.2.Can you give me any link where to download router template on packet tracer? I want to explore cisco 2821 but packet tracer 5.3.2 has an existing of cisco 2811 only then, I tried to add the 4 ports of RJ11 but I cannot see the 4 port telphone.
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.
I am trying to troubleshoot a problem where in one of my remote site is not able to access some networks at HQ over Site to SIte VPN ( asa 5505 at Remote and 5520 at HQ). I ran packet tracer and HQ ASA looks clean as everything came out as ALLOW. Remote site ASA packet tracer give me DROP out at Phase 9 (VPN). I am not very sure what to look in ASA for resolution now. Is it an access list that is blocking the traffice or VPN setup.
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.
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

[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!
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.
I am using Packet Tracer to simulate Cisco networking.As the existing IOS of the 3560 and 2960 switch are in older version which has no new feature in new IOS, how to upgarde the IOS of Cisco switch at Packet Tracer?
Any good way to force a serial link to delay packets to simulate a hi latency WAN link? Found this command so far:
Router(config-if)# transmitter-delay hdlc-flags
I can dial the speed up/down via clock rate all good but I need to also simulate latency. This is for simulating a WAN bonding scenario so I was going to aggregate a 10M ethernet port with a 2M serial and a 512k serial. But I need to also ensure varying latency.
We have an ACS 4.2 installation and we have users configured on the user setup, they authenicate using the windows database (AD). We ran failure tests and simulated AD failure but disabling the firewall rule. So the ACS server is up, AD is down. Tested user login to a switch and get the following error. External DB user invalid. It looks like as the ACS does not get a response from AD it rejects the user login.
What we want it to do is in the event of AD failure is to be able to login to the switch with the username configured on the switch. (as if ACS server does not respond)

Anyone know of a way to run packet analysis against a virtual server without having to install wireshark on said server?The Virtual server in question is very small, however the physical box has a number of virtual servers on it, some of them very big that push gobs of data.Is there any known way to just check traffic against said small server? Or will I have to just bite the bullet and filter the traffic from everything else out?
i have a home lab network that is connected to my internet. I basically have a linksys router connected to cable modem and in order for my families internet to not go down while testing and learning my CCNA I am trying to treat the Linksys as the ISP.
1. Plugged my 891W router via FASTETHERNET 8 (192.168.1.10) into LAN Switch port 1 of my Linksys E4200 home router(192.168.1.1).
2. I plugged my 891W Gigabit 0 (10.10.10.1) LAN side into my 2950 Catalyst Switch (10.10.10.5 - VLAN 1)
3. my 2950 Catalyst switch (10.10.10.5 - Vlan 1) is plugged into my 2600 series router via the routers FE port (10.10.10.2).
There is a few more routers connected behind r2 but I am not dealing with them right now and there is also a switch connected into s1 but its not being used for this.
891w is labled r1 2950 is labled s1 2600 is labeled r2

I can ping all over my homelab everything I can reach as long as I have a protocol up but I cannot reach the WAN IPs. I watched video by Jeremy Ciorara and I tried to follow the wan and nat part from a website [URL] And none of its working. I am not sure if this is a case where a private IP cannot function as a ISP and I am breaking some rule thats not mentioned in CCNA studies or if its something else. I tried these commands from Jeremy Video:
r1(config)#ip access-list standard "NAT_ADDRESSES" r1(config-std-nacl)#permit any r1(config)ip nat inside source list NAT_ADDRESSES interface fastEthernet 8 overload
However they did not work it was pretty close to whats in the basic website up there I listed as well. I think I went back to the basic configuration in the config file post above. Its really frustrating as I follow directions and they do not seem to work. I understand I am using my private 192.168.1.0 subnet as an ISP and maybe that has something to do with it but when yoru first learning and things dont work its kind of overwelming as you have problems seeing the big picture and dont yet trust in things you have learned as they are unfamiliar so its easy to get lost.
I have run into a problem replacing an old Linksys BEFVP41 with a SA520. The BEFVP41 had an address on the LAN defined as a DMZ. That address was another router. It is in the same subnet as the local LAN and I am not sure what ports it uses. It is controlled by an outside group and requires much delay and paperwork to change the address. The new SA520 will only support a DMZ if it is in a different subnet than the LAN. Any way to simulate the old DMZ function on the newer router? I have not yet been able to obtain a list of all ports that should go to the second router. Didn't know if there was a way to forward all ports like the old BEFVP41 does by setting a DMZ address.
I came across a situation where a client had an old PIX 525 running PIX 6.2. There was a Windows 2008 R2 server running Exchange 2010 that was having trouble delivering email to a handful of email servers. We then found out that we could telnet to these servers on port 25 but got no return traffic. We then went back the old email server that was running Windows 2003 Server and could telnet to port 25 on these email servers and got a response, saw the banner and could issue commands. The first thought was reverse DNS which we thoroughly checked and it was not. I turned off the smtp fixup protocol and that didn't fix it either. From workstations on the network running XP or Windows 7 or Linux you could telnet to these servers and you would get a response but just not with 2008 server. I spent hours on the phone with Cisco support and it was determined that the packets were returning and we could capture the packets on the outside interface but they were then dropped by the firewall. Using the 6.2 version of PIX we could not determine why the packets were being dropped. I suggested upgrading to the next major version to be able to troubleshoot the issue further. We then upgraded the PIX to version 7.0(8). After the upgrade we were able to telnet to the problem mail servers from Windows 2008 Server and there were no issues. Is there a know issue with Windows 2008 Server and PIX 6.2?
I have a 5520 in production at a customer's site between an outside 802.11 network and an inside server. The server can get to outside hosts OK, and the traffic is being NATed properly, and sockets initiated by the server on the inside can pass data both ways, but I need to allow outside hosts the ability to send 'announcement' UDP packets to the inside server. I thought this might be an outside-NAT-required issue to get the traffic routed, but I need the inside server to see the actual outside host source IP in the UDP packet, so I basically set the outside host up similar to the inside host, just without the NAT table on the firewall -- it's subnet is outside the destination (inside server) subnet, and its gateway is the outside interface of the ASA, the same way the inside server is able to get to hosts outside. The firewall should just route the packet with a destination of the inside subnet once it sees that it hits a 'permit' ACL.
I have the appropriate ACL's set up, and when I do 'show access-list' I see policy hits for the 'permit' statements where the outside host is generating the announcement and it's hitting the ACL. I even duplicated the ACL into list 101 and 102, and applied 101 for inbound traffic on the outside int, and applied 102 for outbound traffic on the inside int, and I'm seeing policy hits on both permit statements outside and inside, so it looks like the traffic is being passed on to the inside interface and permitted, but the server isn't seeing the packets.
I can ping the outside interface from the outside, but cannot ping the inside interface or any inside hosts from the outside, even though I have 'permit icmp any any' enabled on the ACL on both ints. When I remove the firewall and put the outside clients on the same subnet, the server sees the packets just fine.
I set up the same scenario in my lab with an ASA 5505, with the same results. Below is the running config from the 5505 in the lab. The production firewall is running a slightly older version of ASA, so I made the configuration as basic as possible on the 5505 to match the config in the field:
I have an E1200 and am time out and packet loss issues. The internet connection is fine for 30 seconds to five minuets and then everything times out for 15-20 seconds. Although it’s only a minor incontinence to web browsing, it makes playing games and watching videos a nightmare. “Lost connection to server error.” and the like…
I upgraded to a new router, the e1200 I am currently using, from my Tenda 10/100 N. The problems where the same that I am experience currently and the reason I bought it in the firs place.When I directly connect to the cable modem, I have no issues and everything is fine.I have run a trace route and the second hop, (the router to the modem) is the choke point.I have cloned the MAC address.I have updated the firmware and hard reset
I have throttled my MTU to automatic, 1500, and 1472. None making any difference.I have disabled NAT and all that does is kill my internet connection.I have disabled all firewalls router and windows, no change.I replaced the physical wire from the router to the modem.I have disconnected all devices except one computer, and no difference.I ran a DNS trace and I have… non routable local internet address 192.168.1.1 DNS-cac-lb-01.rr.com and DNS-cac-lb-02.rr.com.I am using windows 7 and my ISP is time Warner so-cal.
I have an Cisco 6500 CS and there is a Cisco Unified Communication Manger Server connected directly to the Core Switch.I tried to change duplex and speed ( fix and auto ) for both sides, but the same problem.
