I'm having difficulty logging onto my 1801 router over the internet I can ping the device and tracert to it but I can't telnet or SSH ,Here is the config - Can you see whay this would happen. Its on ADSL link.
View 7 RepliesI have a cisco 1801 (fixed), and want to use the fe0 WAN port to connect to the internet via a virgin media cable modem.
I am having a few issues (partly as I am new to cisco) and despite reading numerous posts both here and other sites, I am still stuck on how to setup the WAN side, I have read about virtual dial up & dialer interface.
Is it possible to log onto a router over the internet using a pooled IP address? I want to be able to manage some routers that are in different sites, these are just providing internet access to clients. these are 1801 and 877s
View 4 Replies View RelatedI'm trying to set up an 1801 router with two WAN interfaces, fastethernet0 and fastethernet1. On the LAN side, I have two subnets. One subnet's internet traffic should be routed over fastethernet0, the other over fastethernet1.I've setup some route maps to accomplish this. I can surf the internet using subnet 192.168.2.0/24 fine, all traffic goes out of fastethernet0. However, and this is where the problem is, if I try to reach the internet using subnet 192.168.3.0/24, all packets go out interface fastethernet0 with the source address of fastethernet1!When I'm surfing the internet, from subnet 192.168.3.0/24, packets should be going out fastethernet1, now they're going out fastethernet0.

I came accross a Cisco 1801 router. As I understand it supposed to work with a dsl connection for internet access and configuration. I have cable internet access at home and since cisco routers are very versatile, I want to know if I can integrate this router into my home network, as a secondary router, and use it for its SSL vpn capabilities?
View 11 Replies View RelatedI have a 1801 router connected to a 3550 switch with a regular 802.1q trunk, and I am curious as to what may be causing the unknown protocol drops on the connected router interface.
The switch is without any configuration at all except the following for the trunk configuration on the interface connecting to the router.
Switch:
-interface FastEthernet0/1
-switchport trunk encapsulation dot1q
-switchport mode trunk
Router:
-Interface FastEthernet8
-switchport mode trunk
There is nothing connected to the switch other than the router so the dropped traffic must be originating from the switch itself.The unknown protocol drop counter on the router increments by one every 30 seconds, and I tried using a packet sniffer but nothing noticeble showed up.
I read elsewhere on these forums that it might be udld, but that is not enabled by default, and just to be sure I tried disabling it on the interface and as expected it said it was not enabled, so I am ruling that one out.I also read that it could be because the router is recieving traffic from other protocols than IP, but I do not see how it applies in this case.
what does a 3550 send every 30 seconds that my 1801 does not understand?Could it have something to do with STP?
I've recently purchased a Cisco catalyst 2960S-24TS-L & setup 3 V LANS 10 (no current IP),20 (192.168.2.1) and 30 (192.168.3.1) to reflect the router V LAN configuration & ip information. When connecting my PC to the switch to test connectivity on (2.1 & 3.1) I'm unable to connect to the the net but can successfully ping GW (int FE0.20 & FE0.30) 192.168.2.1 & 3.1.
The router is an Cisco 1801 & it seems this is where the configuration issue is but I'm unable to figure out how to complete the setup. It has been quite awhile since I've configured a Cisco router.
Ive never had this router connected to a switch so all router switch ports are in the default VLAN1 (192.168.1.2), with FE0 disabled. In trying to get the switch to communicate with the router I made the following router config modifications.
FE0 enabled with subinterfaces configured
FE0.10-currently no ip
FE0.20-192.168.2.1/27
FE0.30-192.168.3.1/27
I have two issues I want to resolve:
1) I do not know what additional steps are required to allow 2.1.& 3.1 V LANs to access the net.
2) I want to disable VLAN1 if possible & use the network IP for VLAN10 (192.168.1.0). I'm unsure how to do this as any change on VLAN1 immediately breaks router access and the router reconfiguration becomes more complicated with changes to the FW ACL etc.
I have small business server 2003 setup as a DC and did not install exchange, i use hosted exchange. i am trying to setup vpn and have opened port 1723 on both of my router. my network routes through a wireless router(192.168.1.1) (port 1723 forwarded to .1.104) to a second wireless router (192.168.2.1) to my server with two nic cards (.2.2 - external and .2.103 - internal) (port 1723 forwarded to .2.2) i can telnet 192.168.2.2 1723, .2.103, .1.104 - my ip of my second router handed by the first router. my server in handling dhcp and it is disabled on my .2 router. I CAN NOT telnet my public ip handed to 1.1 from the ISP(my internet IP). it tries for about 30 secs and dies.

View 4 Replies View RelatedI have two offices - see attached diagram. They use 192.168.0.0/16 for private IP addreses.They're connected via site-to-site VPN. Mostly works well, except some traffic doesn't return and I think it's due to NAT?When a workstation in remote office tries to access web servers in the local office which using private IP addresses (e.g. .64.40), traffic never returns. The web servers in question are also accessible publically - the Cisco 1801 in local office has a static route:
Local1801# ip nat inside source static tcp 192.168.64.40 80 111.111.111.2 80 extendable
The problem seems to be with the local 1801 router. tcpdump confirms that return traffic exits out of ods1's external interface and tcpdump confirms that traffic does not come into remote workstation's interface (neither with .64.40 as source IP nor 111.111.111.2 as source IP)
Remote887# show ip nat translations - none.

What I don't understand is why a nat translation entry is created. My understanding is that it should only happen when ip packets are sent to 111.111.111.2:80 I don't see that any packets would be sent to this IP address when accessing the site across the VPN - in fact the VPN peer address used is not this one.I cannot figure out why on earth this website cannot be accessed via private IP. I have tried clear ip nat translation * on both routers with no luck.

I have a number of Cisco 1801 routers connected to BT UK’s ADSL2+ Annex-A Wholesale Broadband Connect [WBC] services. The routers are experiencing connectivity issues. There is a cisco product bulletin that defines v4.0.0.18 as the version of ADSL Firmware required on the Cisco 1801 when connecting to this BT service.I would like to upgrade the ADSL Firmware for these routers but I cannot find v4.0.0.18 for the Cisco 1801 on CCO. All the 4.0.0.18 downloads appear to be for various flavours of 800. The Cisco product bulletin shows the 1801 as having the same chipset as the 857,867,877 and 887. Can I use the Firmware from one these 800 models? The MD5 Hash for the code suggests all of the these 800 model use the same code?

I am a Cisco newbie, so sorry if this question/query is really basic. Is there anyway I can test the integrated switch to see if it is faulty.
ADSL line do not activate. Telco Confirmed Like is Okay . They have tested no issue observed. Router replaced but did not work. Supspecting Firmware not compatible with telco . Not sure how to confirm on this.

I recently acquired a Cisco VPN 3000 Concentrator Series (fairly old hardware) without a manual, and I'm trying to figure out how to 'telnet' or browser into the router to access the IOS. The device has been reset and I am plugged into the console. I'm running Windows 7 and enabled the Win7 Telnet Client in the OS. Can any tell me how to do this or at least point me in the right direction to obtain the user manual for basic instructions?
Model number: CVPN3005-E/FE
I found the manual for it after going through some hyperlinks. But when you access the console in the Windows OS, is your network connection supposed to show disconnected, or connected but no internet access?
We have a router that was installed a few months ago which has the following version: 15.1(3)T
I am unable to reverse telnet to a new ASA firewall, however when I move the console to a second older router with an older version of code I am able to reverse telnet
Are there any known bugs, issues with version 15.1. I use the following command as normal: telnet x.x.x.x 2001
i have 68 sites with Routers. On each site I have one equipment DIRECTLY connected to the Router that needs to be accessed by telnet port 23.
I have 15 off this sites that the access via telnet to the equipment’s connected after the routers are not working. These sites are using Router Cisco 3925. The other sites that are working are using Routers Cisco MWR 2921.
Both router models are running the same configuration with no filter on it.
The equipment’s after the routers are all accessed directly via telnet without the router. If the router is directly plugged to the equipment the 15 sites with Router Cisco 3925 are not accessed via telnet.
There is any bug related with the IOS version that Router Cisco 3925 is using?:

Network Setup
===========
2 Site to Site VPN tunnels has been established, it is a hub and spoke topology. The hub is ASA5520 and the 2 spoke are a 1841 and 1801 router. The tunnel is able to pass traffic, it's a full tunnel VPN.The tunnel randomly disconnect for no reason. When I check the logs I can see some errors :
%CRYPTO-4-RECVD_PKT_INV_SPI: decaps: rec'd IPSEC packet has invalid spi for destaddr=x.x.x.x, prot=50, spi=0x5F822579(1602364793), srcaddr=y.y.y.y
%CRYPTO-4-IKMP_NO_SA: IKE message from y.y.y.y has no SA and is not an initialization offer
The actual address have been replace by x.x.x.x and y.y.y.y. I frequently have to peform clear crypto isakmp on the spoke routers to revive the VPN tunnels. Is there a way the tunnel can be re-establish again without manual intervention?This keep happening on a random basis and I have living with it for years. I have looked at cisco website troubleshooting tips and but no luck in finding out how to resolve it.
Below is my config on one of the spoke router:

I have multiple customers with either 877 / 1801 routers with dsl issues, we keep dropping sync , get slow speeds etc,
I have already updated to firmware 4.018, in some cases it has resolved the issue in others it has not, BT say their lines are ok, but still i keep getting issues.
My Setup / I've been lurking on here a while, working hard to understand the basic networking concepts and eventually pursue the CISCO certs. I bought a lab and have since managed to setup a four router config (2610XM-DTE, 2621-DTE, 2501-DCE, and a linksys E1000 with routing, DHCP, and NAT turned off to make it a wirelss access point) with three switches (2@2950 and a 2924XL).
So far, I have managed to bring in my public IP using DHCP, and setup PAT. The network is fully functional, I can ping every interface, and reach the web on host PCs from any switchport. I am also able to telnet into the FastEthernet interface IPd with my public address.
My Issue : My concern right now is in feature support. I recently read on here that CISCO does not support UPnP, and due to my limited resources, I am using the only public IP I have to allow remote testing/learning on my lab. The issue is that I also have a PS3 and XBox 360 on this network that is requiring UPnP for certain online games and features.
The only solution I can see to this problem is to return my public IP back to the E1000 router, which is running RIP Version 2 (white papers said version 1, but a debup ip rip showed that updates were being ignored due to illegal version), and then poing my other three routers to it for outside access.
The questions I have in this scenario:
1. Will NAT still function if I use the E1000 and set the interfaces connecting to it as ip nat inside? I'm assuming that PAT is already hardcoded onto the router to allow for multiple connections to public IP space.
2. If my IP is 68.X.X.X, I set the E1000 to an IP of 192.168.1.1 and the FastEthernet it connects to is on my 2621 with an IP of 192.168.1.2, would it be possible to telnet into 192.168.1.2? If I were to forward port 23 out of the E1000 to the 192.168.1.2 address. Will my login and password for line vty 0 4 understand the request if the original telnet was to my public IP?
3. If all of that is just non-sense, is there another work-around that allows me to acheive UPnP through my E1000, while retaining telnet ability to my lab so I can try things in different scenarios or while I'm away from home?
Is it possible to connect WRT54GC with telnet?

I have cisco 1801W . Earlier I am using ADSL dynamic IP address on RJ 11 through the ADSL Port but now the ISP change the connection to RJ45.
I am trying to configure it but unable to do this. ADSL line is okay because When I am connecting through the ISP router it is working fine.
