I'm using a DSL modem to connect to internet. The gateway machine is a
486 with 2 ethernet cards running RedHat6.
I can't ALWAYS ping nor telnet into my linux gateway. The interest part
however, is that I CAN ping (or telnet into) the gateway right after I
try to access the internet from the gateway. (ie pinging
www.netscape.com from my gateway.)
It seems that the modem sleeps after a short period of time and any
activity from my LAN to the outside world would wake it up. But it goes
back to sleep after 10 mins or so.
I suspect this is a problem with the setup coz I can always ping my
gateway when it runs win98. I don't remember having the same problem
before I upgraded from Redhat5.2.
Thanks for reading.
