I'm moving into a rooming house near Atlanta, Georgia. One of the tenants already has a cablemodem in the house. I'd prefer to have my *own* cablemodem so I can use Putty.exe to gain access into my Cisco 831 router while I am taking Cisco classes at a local Cisco Academy.
I called Comcast and asked if there could be two cablemodems billed to different persons at the same address. They told me that unless you go to the post office and break down the address into multiple addresses (like 3190 to 3190-A, 3190-B, 3190-C, etc.) that this could not be done. I have not as yet spoken to the Post Office to find out how easy or difficult this is to do (their paperwork process). Comcast insisted that this could only be done via the Post Office and I would have to arrange it with them.
The landlord says he will run an Ethernet cable from the other tenant's router to my room. He says I'll have to chip in ten dollars per month for the cablemodem (the cost is more than fair). The problem (of course) is that I don't get a public IP address.
I doubt the other tenant is going to let me fine tune his router so that I have a way to Putty into my router from the Internet when I am at the Cisco lab. I may want to try some of the tricks I learned in the class with my Cisco router.
I'm also not sure how well my VOIP unit (Linksys PAP2-NA) will work through two private network addresses. Since I use VOIP for my phone service, that issue is important two me.
This illustrates the general idea. |---------| PC - 192.168.15.100 | Internet |
----------|router|| Private Network Public | 192.168.15.0 |---|My PC| IP Address | My |10.10.10.10 |----------------|Cisco 831|-------| Network | 10.10.10.0 |---|VOIP| Private 10.10.10.100
As you see, the public address ends on the outside of the other tenants router. My router will take a private IP address from him and support my network.
Can you see any issues or share ideas about this arrangement? Regards,
