You are right, it isn't relayed but for some strange reason i got this
in my logs (the cisco has a helper address)

*Apr 15 15:47:42.249: DHCPD: DHCPRELEASE message received from client
0100.1094.00ff.13
*Apr 15 15:47:42.249: DHCPD: 10.17.255.20 is not a local address.
*Apr 15 15:47:42.257: DHCPD: Reload workspace interface Vlan459 tableid 2.
*Apr 15 15:47:42.257: DHCPD: tableid for 10.0.0.1 on Vlan459 is 2
*Apr 15 15:47:42.257: DHCPD: client's VPN is .
*Apr 15 15:47:42.257: DHCPD: DHCPRELEASE message received

I'm unable to reproduce this. It's probalby just an error on my side;)
