I have been using the 10.0.0.0 block with a subnet of 255.255.0.0. This
weekend I changed my subnet to 255.255.255.0 and found that I have problems
connecting with telnet. I also use ip masquerade on this machine to put the
lan onto the internet using ppp. Ppp works fine but I have found that when
I am not connected to the internet with ppp my local machines cannot connect
using telnet. But as soon as I connect to the internet with ppp all machine
instantly have access to telnet.
I have ran the ifconfig and found this:
lo Link encap:Local Loopback
inet addr:127.0.0.1 Bcast:127.255.255.255 Mask:255.0.0.0
UP BROADCAST LOOPBACK RUNNING MTU:3584 Metric:1
RX packets:305 errors:0 dropped:0 overruns:0
TX packets:305 errors:0 dropped:0 overruns:0
Here is what I think is wrong. Even though I changed the subnet mask it is
still broadcasting with the 255.255.0.0 subnet. HOW OR WHERE do I change
this broadcast?
