3com 4500 DHCP not relaying all options

I configured my 3com 4500 50 port switch similar to the way Amaderog advised in post:
http://www.experts-exchange.com/Hardware/Networking_Hardware/Switches/Q_23866460.html

The only additional thing I had to do on my vlan 1 was to put a static route in my default gateway for my VLAN 1 clients to point the VLAN 1 clients to the 4500 for access to VLAN 2.  The DHCP scop for VLAN 2 has the VLAN 2 IP on the 4500 as the gateway for those clients.  Traffic is flowing between the two VLANs and each VLAN is obtaining proper IP addresses from the DHCP server.

I have two issues.  First, on my DHCP server I use option 252 to pass the WPAD information for my clients to auto detect and configure their browsers.  This does not appear to be passed over to VLAN 2 through the DHCP relaying on the 4500.

Secondly, although the VLAN 2 clients can reach VLAN 1 fine, they cannot pass any further.   When I tracert from VLAN 2 to VLAN 1 clients I can see the route through the 4500 however if I try to tracert past VLAN 1, I get "destination unreachable" right away from the 4500 IP address.

Problem is 4500 because not layer 3 switch.
You need 4800 or 5500 switch for these features.
Vlan 1 and vlan 2 have interfaces configured on the 4500, but it has no routing capabilities between vlans.
Thats why you need more advanced layer 3 switch (eg. 4800 or 5500) and then with udp-helper your option 252 problem can be solved as well.

I thought I replied to this before but the site said it is still open and preventing posting until I reply.  The 4500s are layer 3.
