Cisco Infrastructure :: 1921 - Set Up Router To Provide Internet Access To Local Network
Feb 6, 2013
I've been trying to set up my new Cisco 1921 Router to provide internet access to my local network but with no success. I've been reading guides and looking at videos and I have to be missing something becaouse I can't access internet (ping/tracert) from my local network.
The DHCP server works fine and the clients on my local network gets ip-adresses from the router but can't ping or tracert outside the local network.
I am testing a EasyVPN IPsec server set up on a cisco 891. Here is how I have it set up right now- the 891 is connected to our backup internet connection (different ISP from our main line) and we have a cisco 1921 as our production router.
I am experiencing a problem where when I am on our internal network off the 1921 and I connect to the VPN on the 891 I lose all local network connectivity. Nothing works, can't ping, can't telnet to the 1921, can't browse the internet, its not just DNS either.
I believe the issue lies in the configuration of the IPSec server on the 891 because when I connect to our client's cisco IPSec VPN I experience full local connectivity with no issues whatsoever. It seems to me that ALL traffic is being routed through the tunnel.
Other than the local issues the VPN is working fine and I can remote desktop to the PC I have set up off the 891 and telnet to the 891 from there.

I wounder if there is any way to ping the local deviceses connected to a network hosted by a Cisco 1921 router? I wan't to be able to ping the device(computer name) but currently cant do that.
One of our customer , where there 2 6509 switch , one is Core_sw1 and other is Core_sw2 , catering about 32 Vlan , and HSRP in running for all Vlans , till here no problem , now there internet Router which having one Internet link , which connected and configured on Core_sw1 in a way that one interface of Core_sw1 is given Public IP and there is vlan 85 which internet vlan and vlan 85 ip are natted with that public IP with one simple static route given toward internet router , this is how internet is working ok.
Now i have configured vlan 85 in hsrp as all other are , how can give redundancy to vlan 85 user , that if Core_sw1 get down , internet traffic can get out through Core_sw2.using same internet router with single internet link .i am not talking of ISP redundancy , but Vlan 85 in Core_sw1 goes down , other Core_sw2 will server internet.
What I'm trying to do is create a private network for local file sharing but also have internet access. There is a WRT54G router connected to a satellite modem in a separate building, just barely close enough to connect from my laptop, which is what sparked my original idea to use my WRT54GL as an access point.
Equipment Cisco1921, HWIC-1ADSL, 2 x GB Ethernet interfaces (Only one used for local LAN) Software IOS Version 15.1(1)T2..I have been asked to configure this router to provide an IPSEC tunnel back to our central office.We have been provided with an ADSL business class 7MB service from Telecom Italia, they have presented the circuit to our office with no terminating equipment (wires only). Telecom Italia have provided us with some IP addressing information as follows (I will not disclose the entire IP address) [code]
I can see that the packet count is increasing both inbound and outbound on the ATM interface. I have read many documents and tried many different way to try and get this resolved, I even logged a call with Cisco but no dice.
We are having problems configuring NAT on our Cisco 1921 Router. Below is the running config. The problem we're having is for example our FTP server 192.168.1.16, cannot be accessed from its outside IP address, which is NATed on the router. The server is verified to be up and running and when we do a show debug ip nat, we see the router is translating outside users attempting to access the ftp server to it's correct internal IP address.
The ONLY reason I bought a router was to get connected to my Security DVR. I don't want to provide Internet for a network. Maybe someday but my only wish right now is to be able to view and control my DVR with my computer. It is hidden away and hard to get to at the moment so a Lan connection would be great.
I tried direct connect with a Crossover cable between the DVR and my computer. The network was reporting as "Connected" but I could not see the DVR much less view the video. Their support said they'd never heard of this configuration. Could not understand connecting without Internet and wasn't sure if it'd work without a Router.
So, first I bought a wired router(EBR 2310) because I didn't need or want the wireless aspect. I followed all instructions until it came to Internet connection setup. Then became lost because I don't have a dedicated ISP, I'm using a USB modem for connectivity. I don't have a static IP so could not enter on. So, backed out of setup and entered the IP of my computer to be 1 higher than my DLink routers. 192.168.0.2. Gateway .1, NO dice. Router not recognized.I called support and stayed on the line over an hour. Finally he said the unit was defective. It would not assign IPs theough DHCP. We ipconfiged, pinged reset and all.
I took it back and got an DIR615, hoping it might be a little better. Same problem. Computer says Connected" but when I ping it, there is not sigh of it. I have manually assigned IPs, DHCPed it reset it rebooted my computer, but still no sign of a router.
I need to configure a network in 1 small office space that segregates 2 company domains but allows them to share an Internet connection, a WAP, a couple of printers, and a non-Cisco VoIP phone system. And, it needs to provide guest access to the internet and printers via wireless. I have a SG300-28P, an SA520W, and a WAP2000 to make it all happen. [code]
I configure anyconnect vpn on cisco asa version 8.2. vpn user need to access internet so i configured split-tunnel. the split-tunnel working but i do not want to use split-tunnel for security reason. i want vpn user use our local network internet. how i do it?i think that i must do vpn user subnet nat and then what i need do additionally?
I have a LAN and a DMZ and an internet connection. I am using one of the internet connection IPs to host a HTTP service on a server in my DMZ. (its the same interface as my internet connenction but a different IP to the one used for internet connectivity)
so say my LAN is 192.168.1.x and my DMZ is 172.168.1.x
I can access DMZ from Lan and vice versa. when i try to access the public IP (or URL) from a pc in my LAN i get nothing.
I have enabled DNS rewrite (doctoring) but it is still not working. the HTTP service is available from other sites.
I configure for our office site to site VPN project. Now I configured already Site to site vpn between ASA 5510 and 1841 router.
HQ LAN Branch LAN 10.2.1.0/24 >>> ASA 5510>>>>> 1841 >>> INTERNET <<<<<< 1841 <<<<<< 10.30.3.0/24 ^^^^ Call Manager 2851
Now can access from Branch LAN to HQ LAN each other. I face the problems that are
1) In branch LAN , they can access HQ LAN & resource , but cannot access internet. I didn't configure NAT on PH Router
2) Can I access internet from BRANCH LAN through HQ LAN to INTERNET. Or Can I access Internet from Branch LAN from PH Router directly while access to VPN to HQ LAN ?
3) In Branch Site , hard phone cannot work but soft phone on PC can call to HQ. Hard phone IP are same in Remote Network (172.16.1.0/24 ) . Is it problem ? how can I configure separately ?
Abruptly internet access disappeared. It's a router issue, none of the computers here can connect. Further, I can't access the router through a browser - 192.168.0.1 results in a "Firefox cannot connect" message. I've tried resetting the DNS to no avail. I'm typing via cell phone and it's annoying, but I'm willing to try about anything.
I have been playing around with a 1921/K9 router in our dev environment. It's been about 24 hours and I just can't seem to get it to work. My DHCP Server is working hence my internal network is getting IP address as desired. But Router doesn't seem to connect to internet for some reason.
I am trying to make it a internet facing router with static IP address (67.210.209.113). LAN side of this router will be our .11 Network which is our Dev Network.
Here is some network information:
WAN: Interface IP: 67.210.111.111 Default Gateway: 67.210.111.222 (I can ping this address through router) tlm1921A-11A#ping 67.210.111.222
I have the same 1921 router that I am trying to install at a facility with a Static IP address and Static DNS information to get on the internet and I cannot get the 1921 to access the internet!
Here is my config:

The issue is Windows7 (notebook ASUS N61Ja connected through Wi-Fi) loses and can not find again network HDD storage (Western Digital My Book Live 3TB). Rebooting of the notebook works but after I close HDD folder window the issue comes back. The issue exists only with Wi-Fi connection. Everything is fine using LAN connection.
we use the Cisco VPN-Client to connect to our CISCO1921 Router and want to go out again on the same interface to the internet. We configured the connection with the IOS scurity package, have no split tunneling - so the client is forced with it's default gateway to our router - we also have pushed our local dns-server to the client and he gets dns results. Now I think we have to got out with some kind of NAT, because our client has a private IP from the IPSec Client pool. At the moment we have no NAT inside/outside, bacause we only use official IP addres in- and ouside (data-room usage).
- Is it possible to get the NAT function going in and out on the same interface with crypto_map IPSec user comming in and going out to the internet ? - Is it more secure to configure this with vrf ? - Has some a link to example configurations for this ?
I have some issue with internet connection and Router WRT54G. There is always "Local Connection" but no internet access. I checked that at two different laptops. One with Windows Vista and the other one with Windows XP. Both the same problem. There is a wireless connection with excellent signal strength but no internet access. I added a screen shut to see the Router setting. If more needed I will add more.
I have a trouble to implement dynamic QoS between two sites (Site A, and site B) across low speed WAN link (512k). On each site I have Cisco 1921 router. Most important app is Oracle. Because of slow speed WAN links, I want to avoid exact bandwith reservation for Oracle. I only reserve 5% bandwith for network control(icmp, ssh, telnet...) and want configure next Qos scenario:
1. If Oracle traffic exist on a network, it must have 70% of link speed guaranteed, all other apps (e.g mail, file share, ftp) use rest of the bandwith.
2. If there isn't Oracle traffic on a network, all other apps can use all available bandwith.
Issue descrtption:I used all Cisco guides, but when I implemented this on production it simply didn't work. There is no any significant improvement after implementing this (when I start network file sharing accross wan link, Oracle becomes etremly slow.).Here is configuration wich I trying to implement:
ACL-s and class-maps used to mark traffic:
access-list 119 remark ###QoS-MGMT### access-list 119 permit tcp any any eq 22 access-list 119 permit tcp any any eq telnet access-list 119 permit icmp any any access-list 120 remark ###QoS-DB_ORA###
I have an EA2700 running latest firmware 1.1.38.138827. It is using Cisco Connect Cloud. I am unable to access the DHCP Reservations link under Connectivity/ Local Network. When I click on it, nothing happens. I've tried multiple browsers including IE 10 (Windows 8 RTM), Firefox 15, and Chrome 21. I also tried on a Windows 7 machine with IE 9 and the link doesn't work on that either except that it shows a box that says Invalid Character when I click on the DHCP Reservations link. I see no invalid characters on the screen. Any workaround other than downgrading the firmware or assigning static IPs on individual PCs?Also, on an unrelated note, where is the Dynanic DNS configuration on the Cisco Connect Cloud?
I have a very annoying problem with my Linksys WRT54G2.When I connect a wireless device (laptop, phone, TV, Ipad) to my wireless network I only see a Local connection, no connection to internet. After resetting the router (power off for several seconds) the internet-connection is available again.I have to do this every 1 - 2 days.
we have a ASA 5510 firewall and i have created remote vpn user who connects the internal network via vpn any connect after connecting i want him to only access his internal PC via rdp and not access other internal website or shared folders without connecting to the RDP however now he can access the internal website wihtout connecting to RDP?
How do I access the router's web gui management? I already enabled the ip http server and ip https commands. I have a username and password configured
I open a browser session with the ip address:URL, But I do not get the management GUI. I haven't used the GUI in many years,

I would like to explain my situation. My house has 2 floors. My broadband modem is on the 2nd floor. I have an ea 2700 linksys router there, connected to the broadband modem. However, i can't get a good wireless signal on 1st floor, therefore i bought a second router, an e 4200 linksys.
I searched the web, and connected both routers via Ethernet cable, plugging them in lan ports. The ea2700 was only configured wireless security passwords. The e4200 had it's ip renamed to 192.168.1.2 and DHCP server turned off. Well, i have a problem here. the second router, doesn't give me access to internet.
I have a ace board(Acsm) in my switch 6509.I need provide access for clients over https, my scenario looks like this post [URL] .But, i have only one interface, and need to configure nat for inbound clients, to access the server with ip address of the interface vlan of my ace(if i set ace gateway in a rserver, the ssl termination works). The Topology is: Client(https) -> Ace(Https) -> Ace(http) -> rserver (http). Need to configuring this nat? I need that external clients arrive at the server with the ip of the same network as him, he did not right back the packet to the default gateway, but the origin of the same network as him, so that the communication function successfully, end order.
We are having a SRP526W here which replaced a cheap, simple router. Now we would like to set up the VPN-access for outside clients again. So far this was done by forwarding PPTP (TCP 1723 and GRE) to the Windows 2000 Routing and RAS-server inside the network.According to this post the SRP521W, and therefore I suppose as well the SRP526W, are not able to forward GRE: [URL]
Is there a way to provide VPN access for outside clients with this router? Maybe with L2TP (but then we would need to forward ESP) or IPSec (ESP and AH as far as I know)?
If there is no solution we would need to replace this device again with a cheap, simple router which is able to forward GRE - as you can imagine, we would like to save Cisco from this shame.
I've got an ASA 5505 running 6.3 I've connected the management interface to our management vlan (which contains switch IPs, ilo's etc)Is there a way to allow access to this vlan from another?
I set up my internet access by adsl modem as gateway, then RV042 as load balancer and dhcp server, security by MAC address restriction and static IP assignment. WAP 610N used as access point.works great for first few weeks, then somehow I can't access the network.I've been using linksys on my SOHO network, no problem before (RV042+WAP54g)
Can the Nexus 7000 provide NTP to the rest of my network? Can it be an NTP server? I have the followign ntp configuration on it, and have used the commit command, but it seems to be ignoring any NTP requests from other devices. [code]
I have a Cisco 831 router (c831-k9o3y6-mz.124-5c.bin) that cannot backup the config to a local tftp server. I have seen this behavior on a few different Cisco devices over the years and have never found a solution. The connection is made to the tftp server (in this case tftpd but similar behavior on any tftp server) and a blank file is created on the target machine file system, but the data is never transferred.
The router shows %Error opening tftp://192.168.0.2/router-confg (Timed out) [Failed] The tftpd log shows 5 repeated attempts at the file write.
Connection received from 192.168.0.1 on port 53570 [25/05 11:56:40.922] Write request for file <router-confg>.

This is also stopping me upgrading the image on the router as I cannot transfer in the other direction either.
I have going up the walls the last week.Basically just moved house and got broadband installed, my girlfriends laptop connected automatically, whereas my Compaq CQ60 Presario Notebook WindowsVista will not connectI have checked so many different forums trying to fix this problem, but to no avail im afraid... it looks like there is an excellent internet connection.... but cannot go on the internet because it says "Unidentified Network local access only"
