Is your firewall dropping the packets?( tcpdump or ethereal to check )
Is the DHCP server assigning the correct default gateways, dns info to
both subnets?( traceroute and dig )
Does traceroute from the proxy to a node with a problem go the correct
way? 
Does a traceroute from node with a problem to the proxy go the correct
way? 
Is the proxy configured to allow access from the ip range in question?
( check log files )
