Cisco WAN :: HWIC-3G-CDMA-S - Can't Access Router From Internet
Mar 31, 2012
The problem is I can't access the router from the internet. I am also an ocean away from the site. I have an ugly hack set up where I access an inside PC with Teamviewer and then puTTy to the router, but it is slow, ugly, and doesn't fix my problem. I need to be able to set up internet accessible servers at this location for VOIP, VPN, and REAL remote access.Everything else works fine. Connection is stable. Speed is kinda ******, but that's not so important.
First off some specs:Cisco 2801c2801-ipvoicek9-mz.124-24.T1.binhwic-3g-cdma-sSprint 3G data plan
Ok, I have set up the previous equipment as a router for a branch office where 3G access is the only available internet access.I have had the excruciating experience of talking with Sprint Tech Support, and would rather shoot myself in the foot than do so again.
Here is what they told me: "They block ports, but they can't tell me which ones."Here is relevant info I have been able to gather.The IP connection the ISP gives us is not NATTED. That is the address at wimi.com and show int dialer 0 is the same one.Most forums say Sprint only blocks port 80.Zenmap (nmap for windows) says the router has NO open ports but DOES exist.Router does not respond to pingsCan't SSH into router from internetCan't access a test local server with port 8080 or 8081 open with the correct nat statement in Cisco routerNo filtering access-list for testing The config should be just fine as a base config for using hwic-3g-cdma-s as the main internet access interface for a router. Everything works fine aside from the lack of remote access.
So in my head it has to be one of 3 problems.
1. The card is doing some weird stuff to incoming requests
2. Sprint is blocking WAN requests on port 22, 2200, 8080, and 8081 and pings (tested). Maybe they block all WAN requests?
3. There is something wrong with my config.
why I can't remote access into my router or things to try with the config?
Below are some config pastes:
chat-script cdma "" "ATDT#777" TIMEOUT 60 "CONNECT"
!
ip ssh authentication-retries 2
ip ssh port 2200 rotary 1
ip ssh version 2

I am working on a backup system for my WAN. Verizon quoted the HWIC-3G-CDMA-V to work with my Cisco 1721 router. I have a bunch on these routers on a shelf and thought I would use them for the 3G network. Looking at the Cisco web site it does not list the 1721 as being able to work with this HWIC. I thought it might not be listed as the 1700 series are End of life. Whether it will work?

I have an interesting problem. I've configured a site to site VPN connection between these two devices. I am using the CDMA card as the primary and only outside connection on the 1921. What happens is that by default the cellular connection is offline. When traffic is generated internally from that network to the concentrator side of this scenario the cellular connection goes online and builds the tunnel, no problem. However, I cannot initiate the tunnel from the concentrator side. I think what i need is a way to force the cellular connection to always be on, and if it fails to come back online.

I understand that the PCEX-3G-HSPA requires and a sim card. I also have a PCEX-3G-CDMA-V. Does this require a sim card as well? And if so, where is the sim card installed?

My requirment is to drop the Internet traffic once the Cisco HWIC 3G backup link will become active(attached) .Because I should allow only Business Critical Data allow through that and others should drop. Here are the config I used. In here I used a standard access list to generate intersting traffic which allow all the traffic traverse through the backup link.Can I drop the packets to the proxy (192.168.1.100) using this access list and allow other traffic.access-list 1 deny 192.168.1.100access-list 1 permit anydialer-list 1 protocol ip list 1.Is this the proper way I should follow ? Is there any other good method to achieve my requirement ? [code]

What is the difference between HWIC-1ADSL-M and HWIC-1ADSL without the "-M"?Can either of the above ADSL cards be used in Cisco 3845 router? We are using HWIC-1ADSL-M in our Cisco 3845 routers everywhere?

We have configured new 2911 router with HWIC-2T with it.However we are seeing serial interfaces up, but can hardly ping other end. Again we are seeing a lot of CRC errors on serial interface.
But if we connected same cable, with other old router 2811, it works fine. Confiuration is same on both the routers. [code]

I had purchased a HWIC-8A in an effort to provide terminal server capabilities into multiple routers. I had found a document that I thought would take me through the configuration but it doesn't appear that the command syntax is the same on the 2911's as it is in the document. Does any know how I would need to get this configured on the 2911 router?
Here is the document I was referencing

I have a 2811 router runnning IOS 12.4(21) and have added an HWIC 1FE card to slot 2. But the card doesnot show up in the router and all the three lights on the HWIC card is steady green. I have gone through some cisco documentation and found that i have to upgrade the IOS.
I have few questions before doing the upgrade.
1. Which IOS version should I upgrade to?
2. Will this erase my exisitng running configuration ? I have VPN services, PPPoATM, PBR etc.. all running on this router at present.
3. Presently i have a 128 MB CF card on the router. Will this be enough or do i need to upgrade this card also? Can i choose an IOS which will fit into this card otherwise while keeping all existng features?
4. I want to use the HWIC card for the ISP's internet service through PPPoE. Will this be possible with the upgraded IOS ?

Is there a way to configure a 28xx series router with a HWIC-AP card as a wireless client instead of a wireless access point? There isn't a network drop in the location that I need to place a router, but there is an active Access Point that reaches the area.

I have a 3825 router running 12.4t IOS. I installed DSU/CSU part number HWIC-1DSU-T1 in the router and it does not recognize it. Is this the right card for this router? Is there anything I can look at to determine the issue? I think the router only has 32M RAM. Below is a show hardware. Card is still currently installed.

I am trying to configure a newly installed HWIC-4ESW on a 2811 router to bridge to the FE 0/0 interface. Currently, I have a cheap switch connected to FE 0/0 which in turn connects to all the phones, however now I just want to connect all the phones to the HWIC and have it internally bridge to FE0/0 for the connectivity to CME, etc.

I have 2 ISPs terminating on 2 FE ports on my 2811 router.ISP1 had always been here, used for the following:Internet access to LAN usersInternet access with public IP mapping to servers in different security zones (VLANS)Site to Site VPN tunnels to 3rd party partnersRemote VPN access to 3rd party partners We recently got a second ISP, mainly for the following:Internet access and public IP mapping to servers on seperate security zones (VLANS)Site to Site VPN tunnels to 3rd party partners as above, but different hosts So far, ISP1 and all the above service have worked based on the config below. However, having added ISP2, I have not been able to successfully create the site-to-site VPN tunnels.
version 12.4

ip source-route
!
ip cef

ip name-server 4.2.2.2
ip name-server 137.65.1.1
ip inspect WAAS enable

Whenver I try to establish a tunnel on SDM_CMAP_2 and run a test using CCP, I get 2 failure reasons:
1. The peer must be routed through the crypto map interface. The following peer(s) are routed through non-crypto map interface - 4.58.130.130
2. The tunnel traffic destination must be routed through the crypto map interface. The following destinations are routed through non-crypto map interface - 4.58.130.134
The tunnels on SDM_CMAP_1 are all active Do I need to include a default route for the second ISP on the router? If so, how do I get this done? When I tried it, I had loops on the user LAN segment of the network.

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 an existing C2821 router (2 onboard GE + 1 HWIC-2FE) currently. Like to add another 1 HWIC-2FE. Saw this doc on Cisco website which states Max of 2 HWIC-2FE for Cisco2821. Want to confirm this is indeed so as another link states max of 1 HWIC-2FE.
