Strange internet connection query
I've a PPPOE internet connection with a username and password. The
local ISP guy has put a switch on my terrace and stretched the CAT 5 cable directly into my desktop ethernet card.
So before connecting to the net with a dialer I've an internal IP address
in the range of 192.168.0.* which is given to me by the local gateway (also a DHCP server). Once I get connected to the net I've 2 IP addresses the internal 192.168.0.* and the other live IP.
Now I've removed the CAT 5 cable frm my Ethernet card and attached the
same to my wifi router so now I get the internal IP from the wifi router in
the range of 192.168.11.* I've configured the router with my PPPOE
settings which means even if my computer is switched off my net
connection is on coz the internet wire is attached to the wifi router now.
So now heres the question, yesterday my PPPOE account expired but I
dint switch off my router and today I can still access the net even
though my account is expired!! When I check the tracert command it
shows the first hop as my wifi router then it shows all the internet
routers but NOT the local gateway which used to give me the 192.168.0.*
Does it mean that I've bypassed the local gateway?? Can they come to know that am still using an expired account?
There's no cruel intention from my side but being into IT am just
curious to know whats wrong technically coz I dont know much about the
PPPOE internet connection.

Hi, and WELCOME TO TECHIMO - from the Folding@Home Team (#111)...!
I'm not sure I fully understand your setup, but it could be that because the link is still using the same session it was using (before the account was terminated) that it is still up. Normally (in simplified terms) and unless the session was dropped otherwise, it would "time out" and re-connect again every 8 days.
This is due to the IP address lease, as one of my (old) work customers' had a line that was active three days after their contract was terminated. However, it is possible that the company haven't completed their account closure proscesses too....
With regards to the 'hops', I'm not entirely sure, but it could be that the "LAN" connection wasn't actually set to have a gateway, which would mean that no machines/devices can access the internet through it - which is where your "Dialer" comes into it. Unfortunately, this is the point at which I'm not following your network, as I've never had to have a 'dial-up' with a network, and the "dialer" in another sense would be between your computer and the ISP - so when you remove the LAN cable, you would have broken that link and it would stop...

As far as the first part goes am getting the IP address from my wifi router so I can easily renew my internal IP thats not an issue and still my net would work fine no probs.
As far as the second part goes if you remove the wifi router from my setup then theres simply a CAT 5 cable which is coming from the terrace switch into my ethernet card no dsl modem in between.
In that case, when I use the tracert command then the first hop IS ALWAYS the local gateway 'n then the internet routers which is not the case if am using the wifi router (tracert result with wifi router given above)
Of course if i remove the internet cable from the router or switch it off then most probably I wont be able to access the net but right now am more interested in the TECHNICAL reason as to why its still on 'n also whether they can check my bandwidth activity
