Cisco WAN :: 2901 How To Separate DNS Information For Each Connection
Jan 12, 2011
Basically I am trying to do a bit of a clean up at work and replacing two dlink (home style) ADSL modems with a single Cisco 2901 router with 2 ADSL HWICs. On top of this I want to isolate the 2 connections from each other, that is I don't want to use them as fail-over or anything just as 2 seperate connections. To do this I am using VRF tunnels.So far I have been successful in the global config of the switch and everything works. And when I put the lan, atm and dialer interface into my VRF it connects up all fine.My issue that I am having is that DNS (which is being pulled from the ISP via ppp ipcp dns) seems to just populate the global dns view, not the view I created for the VRF. This results in DNS queries not being able to be resolved but all other traffic is fine (i.e. I can ping and access anything on the net, I just can't resolve names).
If I have 2 ADSL connections, on two VRF tunnels, how can I seperate their DNS information for each connection/VRF tunnel? especially if that information is different as they overwrite the global DNS config each time they connect.... I could (and have successfully tested) statically assigning DNS servers to each DNS view but I would rather rely on each ISP sending their DNS servers as opposed to me hard coding them.

I am trying to make 2 COMPLETELY seperate networks with only 1 internet connection. We have routers, switches and all that. But we need to know how to set it all up. there are 2 companies in the same office, each company needs their own network at which they can view eachothers files but in no way view the other networks files.

My fiance recently signed up for the Screen-wise Panel for Google research. Basically they monitor your TV usage and your internet usage. As part of the program they installed a Cisco WIFI router. I've got no issue with them logging the sites visited etc but I'm a little worried about them possible collecting private information (banking / work related stuff) that I don't want going out there. According to what I've read what's supposed to happen is they replace your router with the new Cisco router.The "technician" who came in and installed the router was actually a builder and not an IT technician and rather than replace our router he connected the Cisco router into port 4 of our router... I wasn't in at the time.
What I was looking to do is separate Port 4 of my router into a separate VLAN that can access the internet, but not access anything on ports 1-3, or the wireless. However, I want to be able to see everything on port 4 from the other side (in other words I want to see "into" the port 4 VLAN, but don't want them to see out). I also wanted DHCP to assign IP addresses correctly depending on where you were plugged in. In this example the first VLAN (your current router ip address) is going to be on 192.168.1.1, and the second VLAN (the new on we create on port 4) is going to be on 192.168.2.1.This is exactly what I'm looking to do, I could then connect the kids machines / tablets / ipods to the Cisco router and have the main machine and my work laptop on the main router... but I don't have a clue how to do it. </quote> Is this something that I am able to do with the Netgear router I own and is it hard to set up?

I am trying to set up two routers so that I can offer free wireless connectivity via three AP's in three adjoining rooms on a first floor and secured wireless and wired network connectivity in upstairs offices. The setup is like this:
Verizon DSL connectivity..static IP
The gateway modem/router is a Verizon DLink DSL 2750B with three ports connecting to three wired Access Points in three first floor adjoining rooms, and the 4th port connecting to a Cisco E1200 (wireless and ethernet router) located next to the Verizon Dlink. I would like the Verizon DLink to give open wireless connectivity via the access points and also connect to the adjacent E1200 router.
I would like the Cisco E1200 to offer secured wireless and ethernet connectivity to the upstairs offices. (connecterd to the Cisco E1200 is a 24 port Netgear switch.)I have spent considerable time talking with Verizon and Cisco/Linksys but have not been successful in just how to set this up.A former tech actually did have this setup but for what ever reason the settings were reset to factory defaults with no written record as to the necessary settings.

I set up my new EA4500 last night, and configured the 5Ghz and 2.4Ghz bands with separate SSIDs (as recommended). While I can see the 2.4Ghz band with all of my devices, I cannot see the 5Ghz band with any of them.I followed the advice given (including the settings shown) on the EA4500 FAQ.Title: Personalizing and connecting to the 5 GHz wireless band on a Linksys Wireless-N routerArticle ID: 21466.Did that *multiple* times, and still nothing. I do have a dual-band capable adapter (Netgear RangeMax WNDA3100 Dual Band Wireless-N Adapter) that I know works on 5Ghz (because I had it working on my old dual-band WDNR3700v1). Similarly, I have PCs sitting less than 20 feet away that were previously able to see the 5Ghz band on my old router, but are now unable to see it on the EA4500.

I am trying to come up with a config for implementing QoS over a 512 kbps WAN link that will traverse voice and data traffic for now. I am using a Cisco 2901 router with 15.1(3)T IOS on it. my config is below
class-map match-any DATA-PRIORITY match protocol citrix match protocol sshclass-map match-any VOICE-CONTROL match protocol skinny match protocol mgcp match protocol h323class-map match-any VOICE match protocol rtp audio class-map match-any ANY match any [ code]...
THE ISSUE IS : when i add in the service-policy output WAN- QOS- POLICY command , i get the error " insufficient bandwidth 256kbps for bandwidth guarantee (180)". if i take out the " bandwidth 512 " command out then i get no issues adding the above command on interface g0/1

I have a Cisco ASA and a 2901 Cisco Router connected via site-to-site VPN. The ASA can ping over the VPN to computers behind the router, but the router can not always ping to computers in the ASA network. When i ping from a computer in the IOS router's 10.100.36.0 network the requests times out most the time; although every few minutes, i will get about 10 pings back, then stops working again.
I uploaded their two configurations.
The ASAs public IP is 20.20.20.5 and local (inside) network of 10.101.36.0/24
The IOS routers public IP is 20.20.20.10
There are many internal networks, but 10.100.36.0/24 is the one with issues.

Its more for information purposes. I am trying to compile some information together to get a better understanding of them so anything generic would do. Such as what it looks for in the traffic to block attacks, negative impacts of performance and a couple of top products I could have a browse of and so on.

I am having problems trying to connect to my wi-fi. I first noticed that I had problems connecting to some types of unsecured wi-fi connections when I was "borrowing" from my neighbour while I waited for telus to install my internet. My two roommates would have no problem surfing but my computer was unable to get any connection to the internet (i could see the connections but never load a page)
Once telus came and installed the internet I was able to get a "fair" connection to the router and surf with decent speeds. About a week after I first started using the internet, my computer started being unable to connect the router. It seems that everything is getting worse and worse. It started by me having to restart the adapter a couple of times to make it work, to me having to delete the network profile and then redo it, to me only being able to connect by using the WPS.
And now my computer can't even get the information from the router through WPS! I would start to point the finger at telus, but every one of my roommates has no problems connecting to the internet, and it's not a range issue (i'm typing this up with my laptop while sitting beside my desktop).

I am in need of some information regarding licesnes on the ASA 5505.I have a client who is connecting their main office to a DR site via a site-to-site VPN. I understand that the standard license for the ASA 5505 is for 10 clients.Does the site-to-site connection consume one of these licenses?Does each endpoint communicating over the site-to-site VPN consume one license also?For example, if I have the site-to-site VPN and 10 servers on each side, would that mean that I need 21 licenses; 1 for the VPN and 20 for each server on each side?

We are looking at buying an ASR1001 but I'm confused by the Licenses and I've struggled to find the information in the cisco data sheets. The router will need to run IPSEC on gre tunnels and I figure that I need the IPSEC license (FLSASR1-IPSEC) do I also require the Advanced IP Services license? or is all that is required the IPSEC license? Is there some sort of list that shows the feature set of each license, they cost the same amount so I'm not sure which license fits what we require best or if we need both.

For some reason, I do not see that AP group appear in other 3 x WLCs. Very much appreciated if someone could point me to the right information or trouble shooting steps.

I am looking into buying an ASA5505 but I would like to know if it is going to work in my setup. I have an Internet connection and 2 seperate networks. I know that the ASA5505 has 8 ports and I would like to know if I can assign each port to a different network zone? I dont want to use VLAN but physical networks. I know it is possible with ASA5510 and above but I want to make sure I can do the same with a ASA5505 (Without the security upgrade). I want to get an ASA5505 unlimited users.
So an Internet connection (with multiple IPs), 2 seperate networks, I want to filter traffic between all 3 and route between them also.

How do I disable fragmentation on a 2901 router? I want it to simply drop packets oversized packets.In my lab, I am trying to test various MTU issues. I'm trying to use a 2901 router to simulate the WAN equipment that my WAN provider would deploy in production. In production i'm expecting the WAN to only support an MTU of 1320 with no fragmentation at all.

Physical devices are a Cisco 2901 (CISCO2901/K9) with GE0/0 configured as 192.168.1.1
Connected through a D-Link DGS-1210-24 configured as 192.168.1.202
Running on a domain with an HP domain server as 192.168.1.2
The 2901 was an EHWIC (VA-DSL-A oPoTS) on EHWIC 0/0/0
GE 0/0 on the 2901 is physically connected to the DGS-1210 which is physically connected to the server.
VDSL 0/0/0 is physically connected to the DSL jack.
So far the configuration reports all is connected, and I can ping the gateway of our ISP (using CLI or Cisco CP); however the server reports no internet connection and no workstations can access the 'net.
Once connected; I'd also like to allow ports through for use on the network (25, 80, 110, 443, 987, 1723) - but not sure on how to do that just yet!
Our IP is 202.27.19x.19x
Our Gateway is 202.27.217.5

I have recently bought cisco 2901 in order to replace it with our 1811W that we have at the moment.When I try to set a failover / backup with rtr; it seems like the function is not valid.Once I select rtr and set the object #, the reachability command is not available.Does that mean this function is not a part from the license package I have?

I have inherited a setup for a custom application and would like to know if this is the only way this could be set up. How would you do it?The application uses dedicated T1 links to our vendors. There is a Cisco 2901 router in the middle providing the connections. Traffic to specific vendor's IP's are routed to their prospective connections. I have attached a network diagram and a config for the 2901. The way my predecessor(s) set this up, each different vendor uses a different private IP address for the internal links. This seems odd to me. Shouldn't there be a way to have only one subnet on the inside and have the links NAT depending on which route it takes? The servers have persistent routes built in them to send vendor traffic to the associated IP on the router. E.g., traffic to Vendor 1 is routed to 192.168.50.1, the 2901's IP address for the Vendor 1 network. That traffic is then NAT'd to an IP address associated with Vendor 1's link and the 2901 then routes the traffic to the Vendor's end of the link.
I would think that I should be able to revamp this so that internally we're only using one subnet and the traffic could NAT at the link associated with the Vendor. I recently had to add the 3rd vendor connection, and wound up having to duplicate what was done for the other two in order to get it working quickly. I didn't have the time to wrap my head around the best way to revamp the whole thing.

I recently obtained a 2901 router running 15.2(2)T to replace my old 877 which was running 15.1(4)M1. The 2901 is humming along quite nicely but I have had difficulty configuring one feature which was working fine on the 877. The router needs to be a PPTP client to a hosted VPN service. On the 877, I had it configured like this: [code] I then had a dialer interface to actually set up the connection, and some PBR to control what went over the VPN. All well and good, and it worked fine. But on the 2901, when I try to configure the same thing, there is no such command as "protocol pptp" -- the only option is protocol l2tp.Was PPTP support deprecated somwhere between 15.1 and 15.2, or does the 2901 itself not support it for some reason? Obviously I understand that l2tp is superior to pptp, but at the moment this is my only option.

I have one router 1841 in which i configured PBR for internet traffic from LAN. I hv two ISPs few server are configured for ISP1 and few for ISP2.I planned to shift my existing setup at 2901 G2 router. when I am configuring the same config on this router so traffic is passing through only from one ISP not from other, if I troubleshoot so I see that the interface which is connected with ISP2 is not getting any input/output packet.
Config is here:
