ICMP access list keywords for traceroute unix application [7:71662] posted 06/30/2003
[Chronological Index] [Thread Index] [Top] [Date Prev][Date Next] [Thread Prev][Thread Next]


Hi

Can somebody let me know what exact keyword (not icmp type number) should 
be used
to enable the incoming access-list for trace route unix application to work 
fine...

I know UDP should be allowed for outgoing and ICMP should be allowed for 
the incoming...
Looking for the incoming side icmp access list "key words"

For looking these keywords I did the following on the router, But its a lot 
and do not know
which one required for unix traceroute.

access-list 101 permit icmp any any ?
