HWIC-3G-CDMA-S is DRIVING ME CRAZY! No incoming WAN access.
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 shitty, but that's not so important.
First off some specs:
Sprint 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 pings
Can't SSH into router from internet
Can't access a test local server with port 8080 or 8081 open with the correct nat statement in Cisco router
No 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.
Any suggestions as to why I can't remote access into my router or things to try with the config?
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
