What you're seeing is correct, if I remember right. A client seeking an
IP address uses bootpc ports, and the server's response is bootps. I
may have it backwards, but I know both are involved in a normal
exchange.

Subject: Reflexive-access list - DHCP - Helper-address
When using access-list with DHCP and IP helper-address, this was the
needed entry:
permit udp host 100.5.14.1 eq bootps host 100.5.46.4 eq bootps
100.5.14.1 is the dhcp router (R1).
100.5.46.4 (R4) is the router configured with ip helper-address. It is
also the router with Reflexive access-list on the interface pointing to
R1.
R1 answers the dhcp request using destination port 67. It seems it
considers R4 as a dhcp server.
Have you worked with similar configuration?
