A bunch of stuff is enabled when you specify a helper address. You have to
use no ip forward-protocol to disable the ones you don't want. Here's the
list of what gets enabled by default:
TFTP (69)
DNS (53)
Time (37)
NetBIOS naming service (137)
NetBIOS datagram service (138)
DHCP (BOOTP) Server (67)
DHCP (BOOTP) Client (68)
TACAS (49)
