(Hi, Chris.) I think you're saying you've made a modem connection to
Internet using wvdial, but then can't get any further?
Do you have a ppp connection established? Is there a default route?
...should show 'default' and 'ppp0', if so.
Do you have ip_forwarding turned 'on'? Try:
...and you should get a result of '1'; if you don't, do:
echo "1" > /proc/sys/net/ipv4/ip_forward
...and that'll put it there. Do you have "policy" rules that are set
to reject packets moving in or out of your own system? Do:
...to find out; if the 3 groups, "input", "output" and "forward" all
show a policy of "reject" (which is their default), you'll wanna change
that. If you're running a standalone system, you probably can do
blanket 'accept' statements and not be leaving your system open to
attack from "the outside world":
ipchains -P input ACCEPT
ipchains -P output ACCEPT
ipchains -P forward ACCEPT
...will do that; it's likely you'll need to do that again, next time
And that's about -all- I know about this. :-) If there are finer
points to it that should be added, maybe someone else will join in here
and let us know...?
