Hi James

Yes I am pinging from a host on E0/0 to 10.0.3.51. The policy is applied to
E0/0 on the router that I am running the debug policy from.

Kinton, I understand what your saying about the last match statement and
I'll add this but the problem is, as you can see from the debug trace that
the policy is making a match and but then rejects the policy and use normal
forwarding to route the packet. What I can't do is find anyway to tell if it
has actually set the ip precedence bit, I'm thinking it isn't. also I 'm not
sure why it's rejecting the policy after making a match, I'll see what it
does after adding the extra match

Thanks for your help so far

                Paul,

                Just a thought on your access lists. You have them listed
as:

                access-list 100 permit udp any eq tftp host 10.0.3.51
                access-list 101 permit tcp any eq telnet host 10.0.3.51
                access-list 105 permit icmp any host 10.0.3.51

                Are you telnetting and/or tftp'ing TO the 10.0.3.51 server
(ie. initiating
                the session from elsewhere)?

                If so, correct me if I am wrong but would you not want to
have the
                _destination_ (the 10.0.3.51 host) in the access-list set to
equal the
                port/type of traffic you are trying to effect? For example:

                access-list 100 permit udp any host 10.0.3.51 EQ TFTP
                access-list 101 permit tcp any host 10.0.3.51 EQ TELNET
                access-list 105 permit icmp any host 10.0.3.51

                Anyone have any ideas relating to this?

                Greg
