Remote Subnet to non-NAT'd host

I've got a pix configured allowing radius authenticated access from the inside interface to a host on a dmz and all works fine.

The host is non-NAT'd so access prompts for SecurID then passes data.

Other subnets on the inside interface cannot access the host. It isn't routing as the request hits the firewall, but then it sends a telnet packet with win=0??

captures of working and non-working syslog below. Any help greatly appreciated.

Thanks
J
