I am facing an issue with a cisco 877 router. I am not able to telnet to this router from outside using the public IP. I have also notices this works when the Nat is removed.
View 7 RepliesWe 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 am unable to Telnet/SSH/RDP from my inside network to my DMZ. I am not sure where the problem lies, I am able to use VNC from the inside to the DMZ (ports 5800, 5900), and also establish connection on Ports (26700-26899). I have a computer connected directly to the DMZ and those services work to all networks on the DMZ.I have attached Logs of successful VNC connections, unsuccessful RDP and Telnet sessions, and the running config.

View 2 Replies View RelatedThe network is set up like this.
Host -----> 3750 (classic) running IPSERVICES stack ----> 3550 router -----> VPN 3005 Concentrator.
IP routing is disabled on the 3750 (it's acting solely as a switch) IP routing is enabled with an EIGRP process running on the 3550 router that has the network for the 3005 broadcasting.
I can ping the vpn 3005 concentrator from a telnet session in the 3550 but not from the 3750.I can ping between the 3750 and the 3550 vlan management interfaces. Visually speaking it's like this
3750 ------> 3550 [Success!!!!]
3550 ------> VPN 3005 Concentrator [Success!!!!]
3750 ------> 3550 --xxxx--> VPN 3005 Concentrator [Timeout....]
I know this because I tracerout to the 3005 from the 3750 and it resolved the default gateway configured for the 3550 properly but then started timing out.
The 3750 is trunked to the 3550.
3750 is vtp client mode
3550 is vtp server mode
I'm wondering if there's a layer 2 issue involved here as it is a VTP domain and maybe it's not returning properly.

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?
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?:
Cisco IOS Software, C3900 Software (C3900-UNIVERSALK9-M), Version 15.1(2)T2, RELEASE SOFTWARE (fc1).ROM: System Bootstrap, Version 15.0(1r)M8, RELEASE SOFTWARE (fc1).System image file is "flash0:c3900-universalk9-mz.SPA.151-2.T2.bin"
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?

We have several routers that can only be accessed on telnet port 6066 (vice 23). I have no global exec privilege so I can not provide config.So my question is: how do you configure the router to accept port 6066 for telnet and deny port 23?

View 2 Replies View RelatedI have a 891 router I have been testing some things on. I have been able to successfully telnet to it in the past with no problems. Just yesterday I was trying to set an interface to have an IP of 10.10.10.2 which I realized was an IP I had forgot to exlcude from DHCP and it was handed out to the computer I was using to telnet in. So I wrote in the exlcude commands and did an ipconfig -release ipconfig -renew on my PC that had the 10.10.10.2 IP. After the renew I was given 10.10.10.7 (put in a few more excludes).However the release dropped my telnet connection and afterwards I was completely unable to telnet in, getting the error that says I cannot open the connection on port 23. I had made some changes to my entire config beforehand which had it switch to use a new public IP. I never saved the changes and did a hard reset by unplugging the router to get my old config back and see if I could telnet after that. Still could not get in, same error. Well I went through and remade my entire config to use the new public IP. My 10.10.10.7 PC can access the internet, DNS, ping the router, all just fine. Still can't telnet. I remade my line/vty config and made sure it matched up with a config I had on another router. Still can't telnet. Last thing I did was go in and manually clear all open line connections. All that is left is an idle 0 con 0 line that it wont let me close. Still can't telnet.What the **** is going on with this thing? I am completely at a loss to explain why I cant telnet. It must be something in my ACLs that I am missing?

I've configured in an ASA5540 (8.4) access to a server in my LAN using telnet with webVPN. I've installed the ssh/telnet plug-in in the ASA and SSH access to the servers works fine but when I try telnet access I always get this error:
Could not connect to: "ip server" 23
Reason: java.io.IOException: Connection failed
It happen with any server I try. I'm not trying to access to the ASA, just servers inside my LAN that I can access with anyconnect correctly. There is a Cisco bug (CSCsq89467) saying that not configuring any Web-acl in the ASA solve the problem. Telnet always show the same error.
I have an early model PIX-515 that hasn't been used in a long time but I want to get it working again in a lab environment. I am at loss right now on how to get into it though.
CONSOLE:
I've tried connecting from the PC's serial port to the units console port using Cisco's blue cable with no avail. All I get is a cursor but no response. I've tried using 9600,8,none,1,none as settings and I can sucessfully console a Cisco 1700 router with those same settings in Putty no problem, but it doesn't work with this Pix. I've also tried using other possible common speeds like 1200,1400,4800,19200, 38400, 57600 and 115200 in case the firewall was set to use those and that didn't work either.
