Notice this is in the wrong forum, sorry!
Thank you before hand for taking the time to read this and respond. I may sound a little silly by saying things you probably know, but I want to make sure I get everything out right.
Here is my current setup:
1 smc gateway through comcast
1 linksys wireless router
5 static ip addresses (I probably only plan on using three, but that is neither here nor there)
1 computer running 2 operating systems that connect wirelessly (Windows 7 is the main OS and the Ubuntu 12.04 Server in Linux is accessed through VirtualBox)
3 additional computers that connect wirelessly
My original setup was to have the gateway connected directly into port 3 of the router. The gateway address was 10.1.10.1. The gateway would give out an address ranging from 10.1.10.102/200 to the computers on the network so they could access the internet through comcast's public ip of 50.xxx.xxx.30. I then set up a 1:1 NAT on the gateway to tell it to take the private ip of 10.1.10.115 (linux server) and point it to my static ip address of 50.xxx.xxx.25. The result was to give my windows 7 and the other computers an ip address of 50.xxx.xxx.30 (comcast's) and my linux server 50.xxx.xxx.25 when checking it on the internet.
Everything seemed to be working well. I then ran into a huge problem with the server when trying to enter in my static ip address 50.xxx.xxx.25, comcast's mask 255.255.255.248, and the gateway of 50.xxx.xxx.30. The server is able to access other sites, ping other sites, and ping comcast's ip of 50.xxx.xxx.30 only when I was using 10.1.10.115 as the ip, 255.255.255.0 as the mask, and 10.1.10.1 as the gateway. As soon as I moved it to my static ip address 50.xxx.xxx.25, comcast's mask 255.255.255.248, and the gateway of 50.xxx.xxx.30 it stopped working completely.
I decided to reset the router and Comcast reset the gateway for me as I obviously had it configured wrong. So now I'm back to square one.
I would like to know how to set up the router and gateway to allow my server to be able to access the internet and the internet access it. I'd appreciate if you could give my a somewhat detailed response as I can't find anything on the internet and Comcast not helping much either. Thanks again!!
