Protocols / Routing :: How To Remove Opendns
Feb 24, 2012
I somehow have managed to get opendns blocking access to websites on my home networkI am the administrator and the only person who would have (accidentally) installed opendns, although when I search through my computer, I don't see any files relating to this.I have done a little research and know that I would have to installed this at some point myself, but I can't recall doing this, and would really like it gone. So far, I have contacted my ISP and asked them to issue me a new IP Address. That did not work. I tried ipconfig/flushdns, ipconfig/release & ipconfig/renew, all did not work[CODE]

I'm trying to set up opendns on my DIR-825, firmware v2.05. Under the Setup/Network Settings I set the primary and secondary DNS Server IPs to the ones from [URL] and save the settings and they don't stick.I have also unchecked the "Enable DNS Relay". Well, tried it on and off and neither pad a difference.

I have a 5508 WLC that for whatever reason cant take any DNS settings, but I still need to get some filtering on the public hotspot side of my wireless network. Can I put the DNS settings on the router that the circuit terminates on? This is the same router that the public vlan is defined on, I'm just not sure if I can put DNS settings in place for just one vlan, and how that'd work.

Will Cisco be adding support for OpenDNS in the next firmware release? I have the e4200v2 and want to be able to specify times when I want the filtering to be off. After the kids go to bed. Netgear allows this with their nicely implemented OpenDNS in their routers. I am currently using OpenDNS with this router but don't like having to log in to remove the filtering and then adding it back on when I'm done surfing.

Recently I have switched from DSL to Comcast Cable. In the PPoE settings you can disable DNS from ISP. However, now since I have to use DHCP I cannot disable the DNS from ISP.If I change the DNS on the LAN or change the DNS in my adapter properties (in local machine) this makes my Brother printer loose connectivity.How can I get the openDNS servers on the WAN side of the RV220?I do not have a static ip address from Comcast either....

How do you properly remove the QOS queues and configs from the switch.A was using auto qos which created a whole mess of qos configs on my running-config. I did "no mls qos" in conf term but that did not remove the queues.

We have a pair of 6509's with duplicate ACL lists & entries.
1 = Version 12.2(33)SXI4a
2 = Version 12.2(18)SXF15a
I wanted to remove some logging that was on an entry on one of our extended ACL's. On 1 this worked fine with the no 400
400 <acl rule without log>
However on 2 it lets me carry out the no 400 command but when i go to add the 400 <acl rule without log> i get the error % Duplicate sequence number.sure enough when i perform the 'Show access-lists <Name>' it is still there!
I have tried the following:
Adding a duplicate ACL entry before it (399) without log and i still get hits on line 400Adding and removing the duplicate created line 399 (without logging) with no issues.Adding and removing a dupliacte ACL (without Logging) after (line 401) with no issues
It looks like it is just this line it seems to think it has removed but hasn't?!
I understand an option is to duplicate the ACL in a text editor remove line, delete the ACL and put the edit back in .....however i wondered if this is something known (bug).

we have a WS-C6509-E WITH SUP VS-S720-10G, and IOS s72033-advipservicesk9_wan-mz.122-33.SXI5.bin. [code]
From, what we can see, whenever we try to clear arp-cache, it doesn't remove the IPs from the ARP. We've checked a bug in the IOS 12.2(33)SXH4 with the same issue, in version SXI4 is solved, but I have version SXI5, it is supposed to be fixed, from this caveat CSCtf16300, since it says it was fixed on 12.2(33)SXI4, it should be fixed on SXI5, right ?

My isp seems to be using a Transparent DNS proxy and I tested DeleGate on a windows PC and opendns works but I would like to set my router to forward all 53 udp to 5353 udp on to 208.67.222.220 so that opendns can work on ipod,ipad and smartphone etc, I have tried to use the following command to set the router to forward from port 53 to 5353 but no luck:
nat mapadd intf=Internet outside_addr=208.67.222.220 inside_addr=192.168.1.66 protocol=udp outside_port=5353-5353 inside_port=53-53 mode=auto weight=10

Lately, Ive been trying to change my router DNS to OpenDNS. Somehow, after changing it, I couldnt access the router page at 192.168.0.1, getting the error 500 message. I unplugged and plugged the router with no effect. Im using a dlinkddns.com dynamic IP, and have a few ports forwarded for my DVR. The router model is DIR 615. want to change the DNs for speed and filtering purposes.

I am running a guest network on my E4200V2. I have changed my DNS servers on the router to use OpenDNS for traffic filtering. The filtering on my non-guest networks is working fine; the OpenDNS test sites are blocked. However, when I use the guest network, the OpenDNS test sites are not blocked. There's obviously nowhere that I can change the DNS settings for the guest network.
I know that parental filtering in the router applies to the guest network, however, it seems that the DNS servers for the non-guest networks don't apply to the guest network. Is this true? Have others seen this?If so, that's pretty disappointing. OpenDNS filtering is much more powerful than the 8-URL blacklist I can create in the router admin. If I want to filter sites for my kids, having a guest network that is essentially wide-open (except for 8 URLs) is not an ideal situation.

I have been using OpenDNS for a long time, and I just got the Linksys E3000. When I tried to change the settings to add OpenDNS it said that some changes may cause the Cisco Connect software not to work anymore.
If I change the Static DNS 1 and 2 [URL] will I still be able to use all of the functions in the Cisco Connect software?

We currently have a stack of 5 x 3750 switches and i want to remove switch number 3 (it has the least number of things plugged in). What will happen to switch 4 and 5 will they be renumbered 3 and 4, and will the config automatically update this if it does?

I bought the EA2700, and put the addresses for the DNS servers of OpenDNS into the Static DNS 1, 2, and 3 so that my internet access is filtered (OpenDNS provides content filtering). However I read online that users can bypass the use of OpenDNS DNS servers by choosing their own DNS servers on their computer network connections.The solution is involves firewall rules that limit DNS servers accessed through port 53 to only OpenDNS.

I have a 6509 running s72033_rp-ADVIPSERVICESK9_WAN-M version 12.2(33)SXH5. Four incorrect bgp aggregate-address statements were entered in which overlap. Attempted to remove the statements but they won't come out.
aggregate address 16.37.31.0 255.255.224.0 summary-only
aggregate address 16.37.30.0 255.255.224.0 summary-only
aggregate address 16.37.29.0 255.255.224.0 summary-only
aggregate address 16.37.26.0 255.255.224.0 summary only
I have entered in the correct statements and have no problem getting those in, removing them, and reentering them.

what is the best way to remove configs from ports (GigE or Fa) in a 6500 that we aren't using anymore (i.e. best way to return a port to default). Remove each line one at a time or is there a command to default a port?

We currently have two 6509's running in VSS, both switches have a WS-6748-GE module in slot 3. I'm in the processing of removing these modules. I will then be replacing them with a different module type, but I need to know how to remove the old configuration of the previous modules.

Any example, tested on 3750-24/48TS and 3750G-24TS to remove the fan to make the switch more silent. I'm not interested in replies telling that is risky, I'm interested to know how is the switch acting. Has shutdown at overheating? I will use the switches only for my CCIE studies, a couple of hours per day, no heavy load.
I tested with 2950 switches are there were absolutely no problems, the devices were even in production.

i want to remove the sync-profile on each of two synchronized Nexus 5596UP without loosing the config stored in Switch-Profile. That means without connectivity interruption and re-configuration of interfaces in "conf t mode", for example. Since NX-OS Release 5.2(1)N1(1) there is a new command
switch(config-sync)# no switch-profile abc profile-onlyprofile-only—Deletes the switch profile without the local configuration.

On a number of 6500 chassis it appears that linecard 3 did exist at somepoint, but was removed.Problem is that when issuing the 'show int desc' or 'show ip int brie' the ports for the still appear, and indeed same with 'show run' and 'show conf'.

I have got a PC at work (Windows XP Pro SP3) that is on two networks with the IPs 10.20.30.167, subnet 255.255.255.0 (internet enabled) and 10.0.0.20, subnet 255.255.255.0 (no internet). On the 10.0.0.X network there is a gateway with the IP 10.0.0.200 allowing access to another network; 192.168.60.X, subnet 255.255.255.0 (no internet). I have added the route on my work PC to access the 192.168.60.X network via this gateway and I can access all PCs on all three networks from this PC.Now, I am using LogMeIn Hamachi so that I can access the networks at work from home. The PC at work is the 'gateway' PC on the Hamachi network. When installing Hamachi it created a new network connection and bridged this connection with my 10.20.30.167 network adapter to allow access to the 10.20.30.X network from an external PC when connected using the Hamachi VPN connection. I have manually configured my Hamachi connection on my PC at home to the IP 10.20.30.169, subnet 255.255.255.0, with the default gateway set to 10.20.30.167. I can ping all computers on the 10.20.30.X network from my PC at home.
I then added a route on my PC at home for 10.0.0.X to go via 10.20.30.167 (the 'gateway' on the Hamachi network). I also enabled IP forwarding on the 'gateway' PC (my PC at work). I can not ping any PC on the 10.0.0.X network from my PC at home apart from 10.0.0.20 (the other NIC in the Hamachi gateway PC) and 10.0.0.30 (another PC on the 10.20.30.X network that is also on the 10.0.0.X network).Now, with IP forwarding enabled on the Hamachi gateway PC I would assume after adding the route on my PC at home for 10.0.0.X traffic to go via 10.20.30.167 that I would be able to ping all PCs on the 10.0.0.X network...I also tried adding a route on my home PC to send all traffic for the 192.168.60.X network via 10.20.30.167 which has a route via 10.0.0.200 to the 192.168.60.X network, but this also did not work.I then tried adding the 10.0.0.20 network adapter into the network bridge that the Hamachi connection made, also keeping both IPs (10.20.30.167 and 10.0.0.20) on this network bridge by adding them into the 'IP Settings' in the 'Advanced TCI/IP Settings'. I also added the 10.0.0.200 gateway for good measure. I still cannot ping any PC on the 10.0.0.X or 192.168.60.X networks from my PC at home.
I have also added the route to the 10.20.30.X network on a PC on the 10.0.0.X network to go via 10.0.0.20 and tried pinging a PC on the 10.20.30.X network but this also has not worked. Also setting the default gateway on a PC on the 10.0.0.X network to 10.0.0.20 does not allow this...Surely bridging the networks 10.20.30.167 and 10.0.0.20 on my work PC would allow another PC on the 10.0.0.X network to access the 10.20.30.X network after adding the route or setting 10.0.0.20 as the default gateway?

I have two computers. Computer A is connected to the internet through GSM network. Computer A also have NIC adapter which is connected to local network with IP 192.168.33.10/24.
Computer B in connected to internet with DSL connection.
On both machines I use TeamViewer to make VPN secure tunnel between this two computers. Computer A gets IP:7.200.100.2 Computer B gets IP:7.200.100.3
How can I access from computer B to specific device with IP 192.168.33.250 which is on local network of computer A?
Is it possible to route traffic from VPN to other local network, or it is some possibility to use port forwarding from VPN connection to specific IP address on the local network to specific port number?

We have a PPPoE DSL link with a dedicated IP providing by a small ISP(ISP A) in Canada. We are having trouble reaching a small group of IPs in the US to be able to access some client resources.We have eliminated all possible local issues by removing the firewall and making a direct connection to the ISP. We have also had numerous tests prove successful when we use other local ISPs.
Trace routes show that the packets get dropped a few hops from the destination on a US ISP(ISP B).The routes even appear to be very similar to the other ISPs we tested. We escalated to ISP A and they say that everything is working properly on their end and the problem is with ISP B. They claim they "have no partnership with ISP B and therefore cannot create a ticket to get it resolved". I tried calling ISP B but I get nowhere because I am not a customer of theirs.
My solution is to give ISP A the boot, but management has denied that request because of the amount of effort required to switch over. How I can escalate this? Is there anyway to go over and above the ISPs?
