[pptp-server] GRE with cisco IOS IP Plus on version 11.1

[Ismandy Ali]

I am trying to run my PPTPD  just like anybody else. I guess i am trying to
run my GRE tunnel thru the cisco router. When I use traceroute	using GRE
packets instead of using udp or icmp, it gave me  error "admin prohibited
error" - !X. more info chk for the traceroute man.
