Cisco WAN :: WRVS4400N Routing To URL Back Onto Itself
Nov 9, 2011
I have an iPad that uses an app to control the house. I create a dyndns url to maintain connection to the house from the outside world. When I bring the iPad onto the internal network, the url routing fails. Externally, it works fine. I think it's some sort of protection that is configured within the router.
Proper configuration to allow the URL to kind of loop back onto itself, when it's in the house? Where, in the configuration, this is set to prevent this kind of routing?
I have a Cisco 8510msr that is connected back to back with a 7206vxr across a 155Meg connection.I receive lots of Output drops on the 7206vxr interface facing the atm switch. When I do the following command:-
kwdair9#sh atm int atm 1/0Interface ATM1/0:AAL enabled: AAL5 , Maximum VCs: 4096, Current VCCs: 27 Maximum Transmit Channels: 0Max. Datagram Size: 4528PLIM Type: SONET - 155000Kbps, TX clocking: LINECell-payload scrambling: ONsts-stream scrambling: ON797522 input, 881483 output, 203946630 IN fast, 223768062 OUT fast, 0 out dropVBR-NRT : 110288 Avail bw = 44712 <====
I only have 44megConfig. is ACTIVEkwdair9# I only get 44Meg of the available 155Meg.There is no QOS on the router and the only commands I can find that vaguely see that refer to QOS are on the ATM switch:-
atm address 47.0091.8100.0000.0007.0d87.b201.0007.0d87.b201.00atm router pnnino aesa embedded-number left-justifiednode 1 level 56 lowest redistribute atm-static?why this is acting like a DS3 link and not a 155Meg link?
I have two site that has a copper wire ( 2 wire) connection between each router ( No Telco in between ). Now I want to use 1921 router with HWIC-4SHDSL-E card to connect these two site together. Can I use attach configuration to make the connection reference from the diagram ?
I have 2650XM router and 2620 Router Both routers have built in WIC T1 CSU/DSU cards

My question is that cisco website says there are two type of cable connections for this type of config --which are --T1 CSU/DSU ConfigurationSet one CSU/DSU to clock source internal, and the other CSU/DSU to clock source line. The linecode, framing, data-coding, and timeslots must be set the same on both CSU/DSUs.Four-Wire 56k CSU/DSU Configuration For my network connection which type of config i should use??Secondly i try to connect these ports by normal crossover cable it did not work.So for this type of connection i know i need T1 cross over cable-- which has RJ 48 connections at both sides.I check cable from ebay which is RJ45 RJ48 cross over -- will this cable work in my router to router connection.
I have 1 2611xm router and 1 2801 router. For my own lab purpose, i want to configure them back to back to support voice services. I don't know what configuration will be required at each end. in 2611xm, i have NM-2V and its also detecting the card, so i hope it will work ? also what commands i need to run on both ends .
I would like configure two router (e.g. 1921) back to back via a 2 pin copper wire. Can I use HWIC-4SHDSL-E card to do it? What is the configuration I can use?

Just to get this clear as having issues with a E1 link with CRC's at one.Router A,Network-Clock-Participate WIC 1,Should router B have clock participate for WIC 1? We currently have controllers set as UNFRAMED but guess we can set to NO-CRC4 both ends and telco will pass this.
I'm looking for instructions on how to setup and connect two RV082 routers together with a crossover cable between their WAN ports. This is to connect two separate LANS together via an ethernet connection. For staging we are setting everything up with a crossover cable in our shop. Ultimately the crossover cable will be replaced by a microwave link between the two LANS several miles apart. There will be no internet connection.
securing a back-toback connection using E1.The connection is between two cities, using 2x CISCO 1841 router + VWIC-1MFT-E1 interface at each city.
The E1 connections has been provided by our local telco, and they are completely private. The customer is a bank, and they asking me if this is a secure connection or not. If possible, we need to guarantee that no body can get access to the bank network even if they brought E1 modem at one of the ends (telco PoP).
I searched a lot but couldnt find a clear document about connecting 2 G.SHDSL routers back to back.First of all I am not sure which type of cable (RJ11) is used for connecting two 878 routers. Does it have to be cross or straight cable.
Which RJ11 pairs will be connected each other [code]
According the configuration samples One router must be CPE and the other must be CO for simulating DSLAM.
I'm having some trouble getting two Cisco 888's to work correctly back to back.. The two routers will ultimately be used in conjunction with a BT EPS8 circuit which is effectively four wires short distance between customer sites. We have configured lots of these using the older Cisco 878's.
Anyway, as i've been struggling to get line sync on site I've gone back to basics and connected the two 888's back to back. However, I've found that no matter what I do I can only get the routers to sync at 384kbps!? And that's with a one meter RJ11-RJ11 cable.. Very strange. When we've used the 878's we get much more bandwidth. I have tried statically assigning the line rate at both ends but it still only works at 384kbps.
I am setting up my lab using two 2901 routers which is running on 15.2 IOS.I am trying to simulate a back to back BRI.BRI Module: WIC-1B-S/T-V3 (x2) one of each router.
I followed this amazing document to understand the concept of BRI and configuration. url..but it never says if i can use the module that i have mentioned.
Q1. What cabling i need to use to setup back to back BRI using 2x 2901 routers with these modules? Q2. What cabling do i need to use. Q3. Is it actually possible to use these 2 modules alone to simulate a back to back BRI..?
I have configured 887 Router. ADSL with 3g(backup) everything is fine but the routing seems not working.interface ATM0 backup delay 120 60 backup interface Cellular0 no ip address no atm ilmi-keepalive dsl bitswap both [code] Tha nat is working but the routing seems not working. When I run remove "ip route 0.0.0.0 0.0.0.0 Dialer0" command I can connect internet. but it did not work. When I disconnect adsl line and run sh route, I see dialer 0 is the default route for 0.0.0.0. I need to configure backup route for 0.0.0.0 network
What the little green/red light is on the back upper left corner of the switch is? It inside a little mesh and I belive it says vt_fail next to it.
Had water get on our switch over the weekend and this guy goes red when I fire off on demand diagnostic, but not relevant errors in any of the logs. Haven't gotten to the point where I am putting data back on the switch yet.

On the tests in WAG-s all ports are forwarding on WRVS and I open 8080 for Remote Management in WRVS. I can get acces to bouth WRVS by Remote Management from outside networks. I make in bouth WRVS client vpn, but when I want connet by OpenVPN Cilent, I have access for few seccend and I get notificatin that the network not respond. Some time i get connection for long time.

When I change ADSL to bridge mode the VPN tunels are working and OpenVPN Cilent connect normaly. But I thing that the solution with adsl mode bridge isn't safely like forwarding ports and routing.
I have a cisco 800 that needs to be reset back to factory defaults. I tried typing in "config factory-default 10.10.10.1 255.255.255.0" at the conf t prompt, but I got an error Invaild input detected at ^ (the ^ is just under the word factory). So after a bit of reserch I came across this command "write erase" that seemed to do something but now I can't get any ip addreses. Here is the running config:
Using 1104 out of 131072 bytes ! version 12.4 service config
On a 6500 switch running ios 12.2, is there a way of clearing all config settings for a specified interface? I want to avoid going through and having to type "no blah blah etc" for each line.
I have set up port forwarding for my WD Network HDD, which runs a Media Server (Twonky). Now, I have tested the ports and accessed it through the internet and it works fine, until... I click a link to open a folder and suddenly I get a "No such page" error thing. I have however identified this problem, it seems that when I go off the main page it re-routes to the original network address, not my IP forward address. For Example if my IP was 82.9.12.456 and the port was 800 i would go to "82.9.12.456:800" and it would load but once I navigate i go to "192.168.0.*:800/*****" and does not load the page. If i then copy and past my IP into the URL it works, but this is annoying.
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 bunch of 3750x switches that each have a 10 gig routed link back to a central 4507 (loopback = 172.30.255.255).We carved up a /24 (of course, the /24 doesn't really exist except in our address tracking spreadsheet) into a bunch of /30's for routed WAN links and /32's for loopback addresses.We started on the low end for /30 subnets (ie 172.30.255.0/30, 172.30.255.4/30, etc.).We started at the high end for the /32 loopbacks (ie 172.30.255.255/32, 172.30.255.254/32, etc.)
Well, when I try pinging 172.30.255.255 from the access layer 3750x switches, the 3750x seems to be treating it as a broadcast ping where it lists each member that responds instead of the regular !!!!! response (this makes think something is odd with the 3750x). Of course, only one member responds (the core). But even the core seems to respond with the other end of the /30 instead of the actual /32 loopback (which makes me think something is odd in the core). I could have sworn that I've setup similar topologies without problems (ie, using 10.0.0.0/32, 10.255.255.255/32, etc as loopbacks) and as long as the mask is a /32, it should work.Also, I can ping/ssh to that loopback if my laptop is on a directly connected subnet. But I can't do it from any of the 3750x switches (which are also directly connected).I've double checked for overlapping subnets, but nope. I don't see any. Routing looks fine. The actual /32 is being propagated everywhere properly.
I have a network that has a pair of 6500 switches on either end, running HSRP. In between each 6500 are two to three ruggedcom switches. They are connected to each other and the 6500's by trunk ports in a straight line. The 6500's see each other as CDP neighbors, and the 6500's can see the rugged- com as LLDP neighbors (ruggedcom only supports LLDP).
The issue is that randomly devices on the ruggedcoms will drop offline and then come back. The problem is that the devices that drop offline are all in the same VLAN, so it appears like a virus - i.e. one device drops off, then multiple. Eventually the HSRP starts flapping between the two 6500s and this causes havoc on the network.I'm almost to the point of taking a laptop and plugging it into one of the ruggedcom's to see traffic, but the issue is that the ruggedcoms are outside in cabinets that laptops shouldnt be exposed to.
The following error was seen on the switch and the Diagnostic Test Loop back failed following a new WS-6748-SFP module installation.Fabric in slot 5 detected excessive flow-control on channel 3 (Module 4, fabric connection 1)
Tried Hard reset of the module and still the error persist.
We recently extended our access layer using a pair of 5ks with extenders. We have a pair of 6509s at our core and they handle the intra-VLAN routing with SVIs. I recently noticed that access hosts connected to the extenders cannot pass traffic between each other if they are in different VLANs. The strange thing is these same hosts can ping devices in other VLANs as long as the other devices are not connected to the 5k environment.
For example, consider the following hosts. Each host has their gateway set to the appropriate SVI on our core.
HostA - VLAN100 - connected to 5k extender HostB - VLAN200 - connected to 5k extender HostC - VLAN100 - connected to 2960 off our core HostD - VLAN200 - connected to 2960 off our core
Each host can ping each other with the exception of HostA and HostB. As for specifics, we use HSRP (no VSS) between our cores.
When I ping between hostA and hostB, I see the egress packets on either 5k1 or 5k2. I then see ingress AND egress on Core1. There are no ingress packets on 5k1 or 5k2.The egress packets from Core1 show the correct destination MAC address of the target host. The mac address table shows the mac address on po31.
I'm having with VSS Failover. Currently I have two 6504's setup for VSS with one connection to the sup engine (10Gig__Connection) and the other connection on the Module 3 10Gig Blade and the same setup on the other 6504.My question is: If the active 6504 has a power outage or the link on the sup engine goes down, and the standby 6504 becomes active, what happens when the Failed 6504 comes back online with a higher priority and preempt set? What happens with the 6504 that took over as Active and now eeds to go back to Standby, what's required?
What I'm seeing is once the Standby took over and became Active in order for him to go back to Standby mode it's asking for a reload to take place is this NORMAL?

We have multiple cisco cat 2900 switches. all switches don't have cascade cable port in back panel. i want some sort of solution to manage those switch remotely.
I have a lab setup to take my CCNA and CCNP and I'm having issues trying to get WAN connectivity back to a switch at the end of my network. My lab environment consists of 1 - 2950 switch, 1 - 2620 and 1 - 2621XM. I have 1 Ethernet connection from each router to the switch and 1 serial connection from the 2620 to the 2621XM. I have the serial interfaces in a shutdown state right now so there is no loop since I do not have Spanning tree setup on the ports on the switch yet.
Right now using the fast ethernet ports on the routers and I have no issues its when I shut down those Ethernet ports and try using the serial interfaces when I start having issues. So my network layout is Ethernet from switch port f0/4 to port f0/0 on 2620 and serial from s0/1 on the 2620 to s0/2 on the 2621XM. My 2621XM f0/1 is whats connected to the WAN and I have no issues getting to the WAN from my 2621Xm or my 2620 but when I try pinging any website or even my WAN default gateway from my switch I get nothing!
Ive also noticed that when I do a IP NAT translation (after accessing the WAN from my 2620) on my 2621XM the source IP is of my serial connection not the ip of my 2620 router? I have my default gateway on the 2620 as the the IP of my serial interface on the 2621XM and vice versa because my LAN network is 172.16.1.0 and my WAN is 172.16.9.0. I have a /31 setup between my serial connections 172.16.11.0 (s0/1) is on the 2620 and 172.16.11.1(s0/2) is on the 2621XM. I used the SDM (ver 2.5) to setup NAT to have f0/1 with Nat outside and s0/2 as Nat inside. Encapsulation is HDLC between the serial links. Ive attached the running configs of the switch and routers.
A customer wants to get the back-plane load of a cat4506-e chassis with a sup6-E supervisory card.A would like to check how many bus are used on the backplane and if the command "sh envi chassis" is the good and only command to be used ?I'm not sur that there is only one bus on the cat4506-E as with a sup7 card the backbone speed can change.

I have a website account with fatcow. I created the website with Dreamweaver software and uploaded it to fatcow via port 21.My internet connection was via xplornet and I had no access problems. I upgraded to xplornet's new g4 system and now I can no longer access my account online or upload to my website.We have two computers. The first is a desktop system that has the dreamweaver software. The second is a laptop which connects wirelessly. We share the signal through a dlink router. The modem is a viasat Surfbeam 2 residential satellite modem.1. When I attempt to login to the fatcow control panel, the tab shows successfully authenticated and then re-directs me back to the login page. This happens on both the laptop and the desktop.
I have tried bypassing the router and the problem still exists.I took the laptop to the computer center and I can login to the account no problem.I used a free proxy server page on the internet and can login from my home system on my desktop no problem.I have completely turned off virus scan and firewalls. It doesn't work. I have tried IE7, Chrome, Firefox and they all have the same problem. The laptop runs IE8 and has the same problem.I can ping the page successfully. I can traceroute the page successfully. I can't nslooup any site at all. I get the domain not existant message.My ip and dns settings are the automatically find option.I have renewed ips and dumped the dns cache.Using alternate dns addresses doesn't rectify the problem. When I attempt to upload via dreamweaver, I connect but within seconds I get a Dreamweaver message that says "Connection to remote host has been lost. Click refresh to continue" and the log reads "FTP Error. Dreamweaver could not connect to server." I haven't taken my desktop anywhere to try to see if it works on a different network. I'm in a remote location (hence the satellite internet)and it is an hours drive to the nearest private internet connection and a 2 hour drive to the nearest public connection.
Is it possible to get a PAK back from a license? For example, if the PAK is joined with the wrong serial number is there a way to revert the binding of the PAK and serial to get just the PAK again?
