I've attached the file which shows the issue which im facing in reachability between a PC to GNS3 router.
Home Broadband ->LAN (192.168.1.1) ---- Win 7 (192.168.1.3) -->Loopback Adaptor(192.168.137.1)---->GNS3(cloud-->Router (192.168.137.2))
Win XP (192.168.15)
[Code]....
We have small which I'm looking to implement and have built this on GNS3.
We have:
Router A in site 1
Router B in site 2
Router C in site 3
Router A and B are connection via a point to point 100M link and from Router C we have a 2 point to point one of which is 5Mpbs and going to Router A and Router B.
For Router C to reach Router A network it will go via Router B and these are 100M connection. When the link between Router A and B goes down. Router C should update and start using the 5m route.
For some reson, the routes are not updating. I have to do 'clea ip eigrp ne' for the routes to update and if I reload the routers all works well, it seems the problem is intermittent.
am using GNS3, and have the 16port switching module. I have created a PC instance and connecting to f/0/0 which is a layer 3 port, I can connect via layer 3 IPs. I then reconfigured and connected the PC instance via a layer 2 port f2/0 which is part of the 16port switch module. All 16 ports are by default in vlan 1. I assigned an IP of 10.1.9.1/24 to the VLAN and gave the PC 10.1.9.2/24. I cannot ping and I cannot even ping 10.1.9.1, the VLAN 1 IP. [code]
View 5 Replies View Relatedwe are moving to different providers. We currently have multiple sites that have MLP bundles going to our current provider. We are trying to limit our network disruptions by creating a new MLP bundle group and connect it to the new provider, but are having no luck. In a GNS3 lab I have setup I am able to keep my existing MLP bundle up/up over the current provider network. When I attempt to bring up a new MLP group to the other provider my MLP does not come up and keeps going up/up then down/down and shows inactive. Is it possible to have one MLP group go to current vendor router, then create another MLP group and go to the other router?

how to implement this on access list
I'm trying to access the CLI on a Cisco Catalyst 4003 switch.
It has a WS-X4012 Supervisor module, a WS-X4232-L3 - Layer 3 Routing Module, and a WS-X4418-GB switching module. Well to make things short and sweet, I don't have a computer with a COM port on it. I need to access the CLI to setup the switch, and I only have a ethernet port on my computer and I'm running Ubuntu 11.10. How to access the CLI? This is just a second hand switch I picked up.
I have Comcast as my ISP and their Small Business Gateway Router/Firewall. I purchased a WRVS4400N and configured them like this:
Comcast Router/Firewall - 10.1.10.1
Cisco WRVS4400N - 10.1.11.1
I turned DHCP off on the Cisco so that wireless devices that connect to it get a 10.1.10 address from the Comcast device. Now, I am completely unable to connect to the web interface of the Cisco, whether connected to it wirelessly or even if I plug directly into one of the LAN ports on it. I have one of the LAN ports on the Cisco connected to one of the LAN ports on the Comcast. What am I missing here? I'm guessing I'm not able to see the 10.1.11 addresses when I am getting a 10.1.10 address from the Comcast, even though I'm connected to the Cisco?
I have a 6509 running catOS that i had to do some routing changes on this weekend. I guess i forgot to set the default route so now I can't login or ping from outside the local subnet and because of acl restrictions on the vty lines can't login from a device within the local subnet. I can login to the sup module so i'm trying to figure out if there is way to get to the switch from the sup like you would access the sup from the switch by inputting the command session 15 or session 16, is there a way to do the reverse to get to the switch from the sup?

View 3 Replies View RelatedI've been assinged a task to connect our branch office with the head office, so that the IP Phones in the branch office can be connected to Cisco Call Manager at head office. To accomplish this they have given a Cisco 877 Adsl router a 10 Port 3-COM POE Switch and 3 Cisco 7911 IP Phones. Currently the there are 7 PC's Connected to 3 COM Switch which indeed is connected to a Internet router(Speedtouch). First I thought of connectiong the IP Phones to the Ethernet Port on Cisco 877 router but had to change my mind as the ports are non POE ports and I do not have adapters for IP phones. So I've decided to connect the Phones to 3 COM Switch and create VLAN's (DATA & VOICE) and pass the DATA traffic through Speed Touch and Voice traffic through the Cisco 877 router, but when I tried accessing the 3-COM Switch via Console I am getting Junk language( See the attachment for reference).
how can I pass through this Junk messeges and access the switch

I’m working with a managed switch that has three V LANs setup on it. Recently the domain changed and the wireless V LAN can no longer access the internal website. I found access rules, in the switch that allowed the wireless V LAN to use the DNS server on the private/staff V LAN. Their DHCP scope is on the switch and DNS is set there. The Website is also on the V LAN with the DNS server. This configuration totally cuts out external DNS usage. It stopped working though. It is as if when things switched on the Domain the wireless users were denied DNS requests. The switch was not touched at that time. I’m looking at it though and it seems that I may have conflicting rules.
The version is 12.2. I believe its a Catalyst 2600~
DHCP scopes: ip dhcp pool INSIDE network 192.168.1.0 255.255.255.0 default-router 192.168.1.1 dns-server 192.168.1.6 192.168.1.4 domain-name saline.lib.mi.us
ip dhcp pool WIRELESS
network 172.16.0.0 255.255.255.0 default-router 172.16.0.1 dns-server 192.168.1.6 192.168.1.4
Here is the V LAN Setup:
Interface Vlan1
ip address 192.168.1.1 255.255.255.0
[code]...
Here are two access lists that should be allowing the traffic from 172.16.0.0 into the list IPs/Ports. These do no work.
ip access-list extended WIRELESS-PRINT
permit tcp 172.16.0.0 0.0.0.255 host 192.168.1.12 eq 30044
permit tcp 172.16.0.0 0.0.0.255 host 192.168.1.12 eq 21326
permit tcp 172.16.0.0 0.0.0.255 host 192.168.1.12 eq 6987
[code]...
During my testing I removed the Deny rule and everything worked. deny ip 172.16.0.0 0.0.0.255 192.168.1.0 0.0.0.255
However, the “ permit ip any any “ rule, makes all the port rules pointless because when this rule is in place solo, I can ping and access everything on the 192.168.1.0 network. Is there a way to deny everything, except what I permit? Because when I remove the ip any any, then they cant even get out. Perhaps there a better way to say, the wireless users can get out but only get into the sub net over specific ports? I have a feeling it may have not be thought out entirely when initially created. However, the big mystery is that it worked before secondary domain controller failed.
I have a LAN with 6 vlans and a 2821 router. By default, intervlan routing is enabled for all vlans, however, I want specific vlans to be denied access to others, though all should still be able to use the Internet being served from GE/0.
View 6 Replies View RelatedI am setting up a link between buildings that uses wireless links. I'm using Layer 3 routed ports on 2 3560 switches to handle the routing between sites. Normally I would just put these in a /30 and then the switches handle the rest. However, the wireless access points have a web interface for managing them that I want to be able to access, but it's only available on the single NIC that also carries traffic. What would be the best way of making this work? Should I make the link a /29 and give the access points an IP in the same range? If this is the case what do I use for the default gateway for the access points?
I have included a diagram to try to explain the issue clearer. The IP addresses in black are what I would do if this were a standard cable (and indeed this will work, but I wont be able to access the admin interface of the wireless AP) and the red ip addresses are the alternative if I use a /29 (but as I said, I'm not sure what to use for the default gateways).
I recently installed a couple of Cisco Aironet 3600 Series Wireless Access Points at a remote site. While I was at the site everything seemed OK, The clients were able to get connected to the access points, the guest network worked fine, I could SSH into the access points, and I could ping them. The problem is when I went back to my home site I tried to SSH into the access points through an ASA IPSec VPN Tunnel and it couldn’t find it. When I try to ping the access points they “time out”. I can ping and connect all other addresses (via RDP, HTTP, etc..) on the same subnet which should rule out an access list problem. A couple of notes to be aware of:
The WAP’s have the Autonomous IOS installed (Version 15.2(2)JB) The WAP’s are connected to Dell PowerConnect 5724 (Not by choice.. We are a Cisco shop, these were already there and have plans this year to replace)
I can ping and SSH with Putty to the WAP’s from the local subnet I cannot ping or SSH from a remote subnet to the WAP’s. I can access all other IP’s and Computers from a remote subnet.
I have recently changed my ISP and as such now have a modem router from them, however I used to have a seperate modem connected to my own router that I have already set up to have port forwarding to my CCTV, DVR and networked storage (Built into exsistine router).Since connecting the new modem router to my exsisting router I have been unable to access the CCTV, DVR and Storage from outside my LAN.
I guess this is because the devices are on the client list of my old router and not on my modem router.Is there anyway I can access the old port forwards through the new modem router, it used to be a matter of just xxx.xxx.xxx.xxx:9966 for example but now this would try to access the modem router and not the router it's connected to.
I have not found any options to disable the router side of it to make it act as just a modem.The hardware is a Virgin Media Super Hub model connected to a D-Link Dir-685.For arguments sake the IP address of my D-Link is 192.168.0.1 and the Super hub is 192.168.100.
