We have two routers connected to the same ISP, both are connected to the ISP through ADSL. Computer a is connected to router A, and b is connected to router B.
tracert from a to B is 3 hops:
- a to A
- A to ISP's default gateway
- ISP's default gateway to B
This is how the network looks like:
---Internet---
_______________ ______|_______ _______________
| | | | | |
a-Ethernet-| ADSL Router A |-ADSL-| ISP |-ADSL-| ADSL Router B |-Ethernet-b
|_______________| |______________| |_______________|
- A's internal netowrk uses 192.168.168.x (subnet mask 255.255.255.0)
- B's internal network uses 192.168.1.x (subnet mask 255.255.255.0)
- ISP's internal network uses 55.65.x.x (subnet mask is 255.255.0.0)
- ISP's Default Gateway IP address is: 98.170.201.1
- ISP doesn't isolate the clients (A and B can 'send/receive' data 'to/from' each other)
- Both a and b are windows machines
- A and B are in different locations
I hope this is informative enough, tell me if it lacks any information.
I want to put a and b into the same LAN (virtually - as if they were in a real LAN. I don't have access to ISP's configuration as I am a client. It's for Gaming and file transfer purposes, and it should not involve the internet as using ISP's internal network is cheaper, faster and more reliable than using the internet. That's the whole idea behind it.
