[NTLUG:Discuss] PPP Internet connection problems - Mandrake 9.1

[joseph beasley]

Your firewall causes the "operation not permitted" messages..

  service iptables stop


Then try your pings.   After connecting with kppp, check
/etc/resolv.conf to see if the dns servers are being added.  You are
getting the default route correctly.
