Cisco WAN :: ADSL2+ Configuration On 2800
Dec 28, 2010
We have a customer in the UK, who is starting to deploy ADSL2+ circuits for the new sites they are adding to their BT IPClear MPLS network.We want to standardise with a config for each site, but to date have found that we seem to be using a different config for each site. Some are configured using a dialer interface & some using a virtual template.
Why on some of the sites the virtual template method works & on others we have to configure a dialer interface. Also in regards to the speeds, what should we configure as bandwidth statements & also for traffic shaping. I know that the ADSL2+ circuits can operate at various speeds, but am i right in thinking these higher speeds are the clock rate of the line & with the BT IPClear product, the customer only gets the agreed/paid for bandwidth.
As this figure is different in both directions, when the traffic shaping is configured using vbr-rt command, is the amount entered based on the slower upstream bandwidth on the circuit.

My client has about 15 public IP addresses for their WAN network. All the internal network IP will be dynamic NAT to these 15 IP addresses to communicate to Internet. Since they are dynamically NAT, if anybody want to access my client internal network from outside internet, we usually advise them to use the whole range of IP.
The modem router used to dynamically NAT these 15 IPs are Cisco 2800.
I am thinking of the configuration using WAN DDNS on this Cisco 2800 for combine these 15 IPs to a DNS name by DDNS method (or any other way beside the DDNS) so that outside people can use one DNS name instead of whole range of IP. In case there is limitation of configuration of some outside people can use only one setting instead of one whole range of IP, they still can access by using one DNS name.
How to implement this on Cisco 2800?

The wireless adapter settings page has an entry for 'PIN' and 'PBC' for WPS.Selecting either always results in the client station requesting the routers pin, indicating that the pushbutton selection is not working properly.The router was doing this with the version of hardware that it was shipped with. i have downgraded to 120522 and the router is behaving exactly the same.Has anyone successfully configured the router for pushbutton connection? do not suggest that we use the pin setting as we have a requirement for dumb devices to connect to wireless and they only support pushbutton connection.

Having just updated the firmware I was surprised that it overwrote my configuration (WAN LAN & WiFi) settings.Is this normal for TP-Link firmware updates ?

We've just discovered it seems the 2800 series aren't getting IOS 15.2?
We're running a 2851 for our CME and specifically want some features in CME 8.8...
End of Sale has been announced, but as it stands you can still purchase this router new today.

I have two CISCO 2800 routers tied together over a Metro Ethernet bewteen an HQ location and a Colocation facility. There are multiple subnets on both sides of the MAN. All things work in this regard.
I added two new Interfaces to the routers to create a VPN failover should the above MAN go down. I use IP SLA to track the MAN, then move to the VPN route when reachability is down.
I can source ping from one CISCO router Interface to the other, through the two interfaces to the Sonicwalls and reach the router interface of the CISCO on the other side of the VPN tunnel.
Problem: I can not ping any subnet behind the interface I ping through the Sonicwall VPN tunnel?
Example 2800 G0/2 interface 100.1.1.41 /30 through Sonicwal over Internet to other Sonicwall and out ot the G0/2 100.1.10.41 /30 interface on the other 2800 router. Ping is fine.

I have a Cisco 2800 router. I have been noticing a lot of traffic to Pandora lately. At times my pipe is 25% music streaming and my router utilization can be quite high. Our web filtering is a hosted service that does not block all traffic depending on some of the ports. It is really designed for port 80 and 443 only.
We decided we want to block access to Pandora completely on both our primary internal LAN's and our Guest wireless LANs.
When I perform the ARIN lookup, I get these results for the IP range:
NetRange: 208.85.40.0 - 208.85.47.255
CIDR: 208.85.40.0/21
The CIDR notation does not make sense to me entirely. The IP range includes 8 class C networks. The /21 is a class b subnet of 255.255.248.0 or a router broadcast address for routing tables (depending on how you want to look at it). I was not sure if I could block the address based on the router CIDR range of if I had to use the individual classful IP ranges.
Should I block "208.85.40.0 0.0.7.255" in my ACL or should I create 8 entries to block the networks like this?
208.85.40.0 0.0.0.255
208.85.41.0 0.0.0.255

I am operating a 2800 series Cisco router. The router is working fine except that I am not able to SSH into the router. I have checked the running config with cisco's documentation and every line is correct. Prior to me getting this job they did an update and think they have corrupted the a certificate key for SSH.
Any command to generate just the SSH key and not all the other keys that would cause bigger connection issues.

I have 2 2800 series routers configured the same, but with different subnets. One works fine, the other the client can't obtain an IP, and hardcoded, cant ping.
I ran DHCP debug and I can see the router assigning the IP, and I see and ARP entry that matches the MAC of the client.

Local LAN is connected with cisco 2800 router and SRX 210 Firewall, currently all LAN segment will go to my Data Center via ISP A and all internet traffic from LAN segment will go to internet via SRX firewall, there is no relation/connection between cisco router and SRX firewall. I have separate AS no. s for both the ISP
I am having attached scenario. based on current one I would like to do following.
1. I need to use PBR at LAN Switch ( its L3 Switch) such that in normal scenario - local VLAN traffic is equally distributed on both ISP.
2. dedicated internet traffic will flow through ISP B only and if WAN link of ISP B goes down, the internet traffic will pass through ISP A.
( in normal scenario, ISP A will utilized 100 % for LAN traffic to reach it to DC but once ISP B link goes down, the b/w of ISP A will be divided to route 50% traffic for LAN segment to DC and rest 50% traffic of LAN segment to internet)

I have an IOS upgrade scheduled on a 2800 router and I have to erase the present IOS. This is a remote location. I am worried that if the new IOS does not work properly that the router will boot in Roman mode. I would still have access to the router via a modem connected through the console of the router.How would I upgrade a router IOS in Roman through a US Robotics Modem connection on the console the router and using a US robotics on my desktop computer to dial into the router? I cannot locate any documents on the Internet about this.

Any known problem with the DRAM on 2800 routers? Over the past few months we have had four 2800s fail to reboot after power off/on and in all cases this was due to faulty DRAM. All four routers had been working fine for months with no problems and only failed after being rebooted. They all failed when trying to load the IOS into memory and therefore all got stuck in rom mon. The compact flash cards were all ok as a working 2800 booted up using the flash from the faulty routers. I haven't seen a field notice so are we just unlucky here?

I have applied a crypto map (fo ipsec vpn) on the dialer interface (for PPoE connection) in Cisco 2800; every time when the router restarts the crypto map is removed from the dialer interface even though i save the configuration every tim when i apply the map on the interface. Is there any way that the crypto map remains there on the dialer interface after the restart of router.

We have configured an cisco 2800 for vpn clients. The weird thing is that after some time (not specific time interval and no idle connection) asks for re-authentication. Some times after re-authenticating session disconnects.

We recieved this for one of our routers. Rebooting it worked, so it's likely a software bug and we will upgrade the IOS soon, but I would like to understand what these log messages.

We have a cisco 2800 router and are now required to allow users to be able to connect to another company's extranet. Having tried this it wont allow this connection so I have added this to the access-list 101
access-list 101 remark SDM_ACL Category=0
access-list 101 permit ip any host 192.168.0.246
access-list 101 permit ip any host 192.168.0.247

I dont think the gre is being allowed back in. I have attached a cut down copy of the config. I have just general experience of cisco routers and not cisco qualified.
