DHCPv4 relay query

[ameen.shajahan at wipro.com]

Hi all,
I am trying to run ISC DHCP v4 relay in our system below.

eth0                                                                                                                       eth0.1            eth0
DHCP Server---------Switch-----------Our own network-----------------------Relay---------------------PC
10.46.185.77                                                                                                 30.30.30.1           30.30.30.32

In DHCP Server I can able to see upto DHCP offer message, so I captured the packet and it shows source/destination port as 67 only.
Usually in relay the source and destination will have 67 /68 and it change accordingly.

Both eth0 and eth0.1 IP of relay pings from DHCP server. Then I don't why the source and destination port as 67 alone.
If somebody knows how to test relay for this setup .
Please let me know that would be great help for me.
