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.
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 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 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 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
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!
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?
The router receives a packet with a destination of 172.16.1.130. which route will Router-C use to forward the packet? [code] The answer that the book give (Cisco's routing protocol and concepts) is: E however, and this is where i am confused, why isn't the answer A? This answer covers the left-most bit.172.16.1.0
it is possible to route netbios broadcasts between VLANs using a RV180W. Presently i have the network configured with two vlans (one for each building). The RV180 operates as a DHCP server and internet gateway for VLAN 1 and a linksys product operates as the DHCP server and internet gateway for VLAN 2.With the addition of a static route between, we can ping freely between the VLANs, transfer files, etc. However, members of VLAN 2 must be addressed by IP in windows explorer by members of VLAN 1 and vice versa. I understand this is because Netbios broadcasts are not routed between the two vlans, precluding addressing computers by name. While this is not a critical problem, it would be "nice" if i could configure the RV180 to route only Netbios between the two (still hold other broadcasts such as DHCP). I understand this ispossible on higher-end cisco products through the use of IP-Helper addresses, but I cannot find any information on doing such on the RV180.
I have ASA 5505 Firewall with security plus license, I configured two V LAN 1 and V LAN 5 as my inside V LAN for different sub net, i need to route the traffic between this two V LAN's through ASA. I configured
int vlan 1 nameif inside Security level 100 Ip address 172.16.100.1 255.255.255.0 [Code] .........
The problem is i am not able to ping other sub net, for ex my PC is in V LAN 1 not able to ping 192.168.22.1 ... For troubleshoot i type debug icmp trace while pinging other subnet
ICMP echo request from 192.168.22.2 to 172.16.100.101 ID=512 seq=4608 len=32ICMP echo request from 192.168.22.2 to 172.16.100.101 ID=512 seq=4864 len=32ICMP echo request from 192.168.22.2 to 172.16.100.101 ID=512 seq=5120 len=32ICMP echo request from 192.168.22.2 to 172.16.100.101 ID=512 seq=5376 len=32
I have 2 Vlans with seperate networks and want to create a route between one server in vlan 465 to another server in vlan 436 via port 80.Vlan 465 has a ASA 5505 inside that IP address 89.254.12.35 will be initiating the connection to address 10.200.1.213.
-Vlan 465: server address 10.200.1.213 -Vlan 436: server address 89.254.12.35
However for extended security I would like to restrict the firewall opening to an IP to IP opening.
How can i route internal VLANs on a 3750X , my current network its small ( about 8 -10 subnets) so i dont wnat to add overhead using maybe dynamic protocol , My scenario is my stack of 3750X ( 2 switches) will be my CORE SW, i will have 2 stack more (2960S - 4 switches ) and it will connect to the 3750X with a trunk port etherchannel each link connected to a different switch, ( i was planning to use a L3 routing in the 3750X but not sure how it will works )
My core SW 3750X it will be connect with a firewall for aVPN , by a Layer 3 interface (using a static or dynamic protocol)
I've been given the task to clean-up our network config, and have walked into a disaster zone.We have a 4510R on site with everyone using the default VLAN, VLAN 1.I have created 4 new VLANS, VLAN100, VLAN150, VLAN200, VLAN250 I have assigned interface addresses to each VLAN and configured Inter VLAN routing.I can route to and from each new vlan with no problem, i.e VLAN250>VLAN100 VlAN100>VLAN200 etc but I can't route to VLAN 1(Default VLAN) from any of them, I can ping the interface on VLAN 1 from any VLAN , but any hosts are unreachable. On the flip side , from VLAN 1 I can route to all of the VLANS.
WE have to deploy ASA5585 in between User vlans & server vlans. we have to find all the ports that needs to be opened on firewall. any tools to do same.
