2821 router to access T1 on LAN
I'll put up a Cisco router for a T1 line for the first time and I hit a barrier. The router, a 2821 with WIC-1DSU-T1-V2 is online (all statuses are rising and I can ping outside sites). However, a laptop computer connected to the router can not access the Internet outside.
My router (sterilized) static IP from the ISP is 10.0.0.222. It is on the 10.0.0.220/30 network, with a broadcast address of 10.0.0.223/30. The ISP gateway is 10.0.0.221
I have the Gigabit Ethernet port game with an IP address of 192.168.1.1/24
Here is the configuration:

end
Since the router command line I can ping 10.0.0.221 (Gateway ISP) as well as external IP addresses. Domain names resolve correctly and can be crazy. I ping the router of my regular Internet connection.
However, when I join a laptop the GigabitEthernet0/1 (static IP address of the laptop is 192.168.1.2) I can't seem to the outside network. I can ping the map T1 and Ethernet card address, but not the ISP (10.0.0.221) gateway or all other external addresses.
I tried to adjust laptop, gateway 192.168.1.1 and 10.0.0.222. Set to 10.0.0.221 gives an error "network unreachable".
I am new to Cisco routers, so I guess it's something simple, maybe an IP need rule of routing or something?
In summary: the router is online on T1, can ping and ping, but laptop connected to the ethernet router cannot be accessed outside the network.
Thanks for any help.
Hello
I guess the problem is that your ISP does not know how to route the packets back to your 192.168.1.0 subnet. If you ping the router with the address of the source of your inside interface it will confirm if this is the case or not.
You can run a dynamic routing with your ISP Protocol which I guess is not the solution preferred the complexity. You can ask the ISP adds a route to your network, but again once I guess that's not an option.
The most appropriate solution would be to run NAT Network Address Translation on your serial interface and use overhead NAT to translate entire your network to your unique WAN address.
Hope that helps.

Hello guys,.
Read the user manual before you buy, I found something that annoying me...
On page 19 of the Manual, I found:
Mode access point, you can connect your computer or WiFi device to the Extender only using a WiFi connection.
Then... IF mode Access Point, the other 4 LAN ports are not usable as a switch?
Is it not?
Thanks for your time.
In Access Point, the LAN ports are usable.

Cannot access a remote LAN with Cisco Client
Hello
IAM using an ASA 5505 and connect with the Cisco Client 5.0.02.0090. The Client connects to the Remote LAN and get an IP of the SAA.
But I can't access the Remote LAN or ping the Interface of the ASA trainee.
Can someone help me with this problem?
If the client computer is in the same subnet as the other PC, then its dislikes a question ASA.
Just make sure that the client computer is in the subnet, default gateway of 192.168.20.100 192.168.20./24 and connected to a switchport on vlan 1.
Finally, check whether the DNS resolution works, or if you can browse the internet with the ip address.

model orientation of 2821 router please?
I need to upgrade the ROMMON to correct a problem of vulnerability (PSIRT: 62573_FN_62573_RouterAS535) and I try to load the file recommended ' C2800NM_RM2.srec.124 - 13r.T5 ' in our 2821 routers... can someone tell me what directory to put in it please? I tried everything I can think of without success. Just, he's missing, use my TFTP try again and then abandons the session. Thank you! Best regards, Michael
Hi Michael,
1. instead of upgrade the ROMmon to 12.4 (13r) T5, please consider upgrading to version 12.4 T11 (13r) that this version is the ability to allow the router to boot via USB.
2. can you have physical access to the router? The router has two USB ports, you can put the IOS in a USB key (as it has supported and correctly formatted).
To apply the upgrade ROMmon, the command is:
TFTP: upgrade the rom t fileftp: / //filename
USB: upgrade the rom usbflash0 file / 1:filename
In all cases, you will be asked a yes/no question, and if you press on 'y', the router will upgrade the ROMmon and recharge.

Customer remote cannot access the server LAN via VPN
Hi friends,
I'm a new palyer in ASA.
My business is small. We need to the LAN via VPN remote client access server.
I have an ASA5510 with version 7.0. I have configured remote access VPN and it can establish the tunnel with success. But I can not access the server.
Client VPN is 5.0.07.0290 version. Encrypted packages have increased but the decrypted packet is 0 in the VPN client statistics, after I connected successfully.
Next to the ASA, I show crypto ipsec sa, just deciphering the packets increase.
Who can help me?

VPN - cannot subnets behind 2nd router internal access. Help.
Hi guys,.
Looking for a little help after a day of frustration. I'm really new to this and student so I know I'm doing something stupid. In any case, I bought an ASA 5505 and placed it between my cable Modem and router Cisco 3745. The external interface on the ASA is dhcp, the inside interface is 192.168.100.1. The external interface of the 3745 is 192.168.100.2 and inside is 192.168.1.1. The VPN pool is 192.168.200.10 - 192.168.200.10.
These are the problems...
1. when I set up a VPN to ASA session, I can ping and access resources dierectly connected to interfaces of the ASA and the 192.168.100.0 internal ASA network. However, I can't access any resource behind the 3745. I can't even ping 192.168.1.1.
2. Although I believe I sent split tunnel, I can't turn to the internet when connected to the VPN.
Here's my network and my config ASA topology and router config...

Newbie question route-map/access-list
I am quite new to the thing whole cisco here. I'm very hesitant to make changes as I am not sure that I take down the entire network of 200%. (We are a very small company)
We have a router cisco 1811 (yes I know its old)
We now have a road map and I'm trying to understand it to make it work the way we want. Basically, we have a few servers and we do not want some servers to use our cable internet connection, we want to use our T1. Our T1 uses an ASA5505 as a router. I don't know why, I know its not the best practice but I was just hired and that's all I have to say on this subject. I am doing as a result. Web traffic currently out our interface cable, everything, including the speed of transfer on speedtest.net out our T1. This makes the bad, bad VoIP phone calls. We also have a tunnel punch in Q1 of our other offices as well as our server Exchange2010 using T1. If our cable goes down, everything for the T1 (by design). We have a long list of defined access our route map - use corresponding ip. I want to change the access list to not allow local network IP addresses. I know that if I put in a whole ip allow it break our network and nothing comes out of the T1 line, and no one can get to our mail server more. So, I was thinking of adding some statements, but I was wondering if someone could help me with logic, so I know not if I will break the network. I wouldn't pull the laminated cord and use the console. (I really need get a USB serial interface). Now, you understand a little more about my situation now for all numbers, etc.
Network internal 90.0.0.0/24, 192.168.0.0/24 192.168.30.0/24, 172.20.0.0/16 (we use only 40 addresses, why they chose 16 is beyond me, stupid really)
PTP VPN: 192.168.116.0/24 comes and goes out our T1.
1811 router: 90.0.0.254/192.168.30.254/192.168.0.254

who will ALL break so we can not communicate with anything? Or is that what I did to do this, we get internal routing etc.? Also, I guess I'd put in 15 IP addresses that are coming in the SAA as well? (We have public IPS 14 (one for the T1 gateway) that would go as well?) I don't want to try to put in those at the top and make sure no one can do anything. I hope I made clear what I'm doing...

I have not read this thread well enough to be able to talk to the intricacies of the issue whether this access will make what you want. But I can answer the specific question you are asking. Yes - the access list is top-down, transformed and if a few more top line in the access list matches, then treatment for this package will not get the license at the bottom of the access list.

Dear Sir.
Praposed connectivity for voice between neighborhoods General remote IP phones to analog phones is regarding the attached flowchart. Cisco 2821 routiters with IOS 12.2 are interconnected (v.35) line using rented between HQ FOR REMOTE SITES. To remote sites analog phones are connected to the FXS ports. To end HQ PABX with the required number of user liseces for IPPHONES is connected to the router via an ethernet switch. It is the installation of the network shown in the diagram is correct for connectivity you want between phones ip HQ for analog phone of BRANCH. What should be the requirement of configuration in the router for connectivity abive.
Please give me some examples
Thank you & best regards
Srinivas
Hello Srini,
your lab configuration is similar to what I guessed.
the IP PBX has an IP address on the same subnet IP to the lan from 2800 HQ interface.
You can run a routing protocol on the V.35 point - to - point link in order to advertise the subnet LAN of HQ.
In addition to what was already mentioned in my first post the use of QoS for a priority queue VoIP calls is recommended.
The part of QoS can be added later to the installation of laboratory.
Hope to help

Nighthawk R7000 AC1900 Smart WiFi router prevents access to Internet
Yesterday morning I lost the internet connection. After a day of trying to solve the problem, it has been determined that the Nighthawk is not only not allowing Internet access, but it stops it completely.
If I plug the computer directly into the modem provided by Midco, I get a perfect connection.
The minute I try to access Netgear genius to solve the problem, I lose the internet connection.
If I try to use the Wi - Fi connection, instead of cable, I lose the internet connection.
If I connect the modem to the router and the router to the computer, I lose the internet connection.
My router $ 199 is barely 6 months. The cables are in good condition. Of course, it would start to have problems after the free 90-day warranty/help from Netgear.
Any help to fix this would be greatly appreciated.
After that four days back with the company support Internet technology, they kept swearing that the router has gone bad. I went out and bought a new one, and it is same thing. They said they would have to call a technician to come to the House because they didn't know that their modem is not the problem since I could not in direct line with the modem to the computer. On a whim, I went out and bought a new modem, plugged into the router and the ethernet socket worked perfectly. If it turns out that something was going on with their router where it would not go to the modem to the router to the computer. When I tried this way, with the old modem, both the old and new router would not recognize the cable from the modem to the router, any cable, we used. But the new modem with router old and new work took over the old modem to the company and they told me there might be a short circuit in the modem, otherwise they cannot explain why the problem happening.

Unable to get online with new router-"Local access".
Original title: can't get online with new router.
I'm having a lot of trouble to get online with my laptop.
My roommate has recently got a new EE Brightbox. It works perfectly well with his laptop and mobile phone. Also works with my mobile phone. However, when I try to use my laptop it only gives me "Local access". I have no problem connecting to the router, but it just won't let me go online.
Tried to disconnect/reconnect the connection Wireless on laptop from scratch with wired connection to router, router and router reset re-booting. None of them have worked.
Any help would be great?
Laptop works on Vista.
Hi Rob,

configure my WRT54G Router as access point?
Hi all, hoping someone can explain the process of setting up my WRT54G as access point to connect to my new WRT310N router. I get under the floor and string a long ethernet cable to add wireless across the House but I don't know how to properly prepare for the router, if I can set up once it is hooked, etc.. ? I've read conflicting reports on the question if I need to change the SSID and if devices hooked to the point of access can still obtain IP addresses dynamically.
The mixture of N and G will be as problematic?
best,
Chris
For General configuration, see here.
Use identical settings SSID und on both wireless security. Use many different channels. Then you have a roaming wireless network.

WRT54GS V5 - router to access the problem after reset
My router worked with the exception of not being able to add a new laptop to wireless access. I suspect that my original password may have been messed up in the last two years, I've used it. I decided that I had to reset to the factory settings and start over, adding MAC addresses and passwords reset.
After several attempts, I started to enter a password loop where she'd just off the coast of the verification of the settings and come back with a new password box. I have tried both direct access through 192.168.1.1 and using the V5.2 Setup disk.
After these failures, I checked your forums and elected to try a hard reset by:
(1) power off router, Modem & computer.
(2) disconnect all cables from the router.
(3) power of router, enable 3 m restart
(4) press on & hold reset for a minute, watching the power button flashes. Observed and released continues to Flash. After a few minutes, unplugged the power supply to the router.
(5) PC cable reconnected to the #2 port. I hit the brakes the cable Modem as I suspected my computer trying to autostart AOL may have had a problem.
(6) set the router under tension and allowed him several minutes to restart, then power & started the PC.
(7) indexed in 192.168.1.1 and it entered my screen AOL (with AOL not connected, & no modem connection).
(8) start of Linksys screen seemed to ask for password. I entered "admin", then after a break but I have once again the password screen. Reinstated 'admin' a few times more.
(9) even and repeated steps 7 & 8 again with the same results.
(10) using the CD Lynksys v 5.2 access attempt. -with the same results: a password loop.
I concluded that I needed to update my firmware before trying again. I managed to download the file for the V5, but when I tried to run I had a matter of Windows 'OPEN WITH?'
I have absolutely no idea and was not able to find an answer in this forum, although I don't know that there is somewhere. If I can't find it, though, there is not. It took me a few hours to find how to add a new topic in a post.
I hope that someone can suggest something. The router works fine with systems that were connected to the front. I also noticed a reference to the evolution of one of the parameters to 192.168.2.1 (or something). I'll have to try to find this page.
This Site is very difficult to navigate. I also tried copy and paste comments to the WORD, in a format that is more practice/more dense with some difficulty because of the color of the text. The Site is pretty (and I'm an industrial Designer) but the function must always take priority.
Thanks in advance,
Norm
The reason why the admin does more work as router password because you have setup a router password, not knowing, in the first time install you your router... If you remember the router password when you used all first your installation CD to install your router then enter this password...
If you don't remember the password, then you need to reset the factory settings (I know that you have already reset the router) is...
Press and hold the button to reset for a minute... Release the reset button... Unplug the router power cable, wait 1 minute and re-connect the power cable...
Make sure that your computer is set to "Obtain IP address automatically", disable any firewall, the security software on the computer...
Adjust the browser settings - open an IE, click on tools > Internet Options, and then delete all files, cookies, history, forms... GoTo 'Connections', make sure that never Dial a connection is selected, click on network settings and make sure that all the options are unchecked... Once you are finished, click OK... Close IE and reopen...
Open an Internet Explorer browser on your computer (desktop) wired page. In the address bar type - 192.168.1.1 and press ENTER... Let the empty user name & password use admin lowercase... See if it accepts...
If the above fails, connect another computer to the router and see if you can access the router web interface...
