HI Guys -

Here's what I am trying to do:

We have a 3550 offloading port 80 traffic onto a Bluecoat, and we are
currently using a port off of my company's 6509 to provide internet access
to the 3550. They have assigned the 6509 port to a new vlan 75, and we
cannot ping out to the internet from our 3550. 
The connection is up, and any pings to the internet stop at the 6509. So my
task at the moment is to be able to see the internet from the 3550... Can
someone please have a quick glance at the below configs and see if there are
any addressing mismatches or something that would cause the 6509 to drop any
traffic originating from the 3550 please? 

Vlan config on the 6509:

interface Vlan75
 ip address 5.75.254.253 255.255.0.0 alt ip address 5.75.254.251
255.255.0.0
 ip helper-address 5.1.8.2
 ip helper-address 5.1.12.32
 no ip redirects
 standby 1 timers 1 3
 standby 1 priority 50 preempt alt standby 1 priority 25 preempt
 standby 1 ip 5.75.254.254 alt standby 1 ip 5.75.254.254
