No internet access for odd IP addresses

That might sound like I need to verify IP addresses, but that is not the case.  I have an interesting problem that I need to address and was wondering if anyone had any insight or experience with this issue.  We recently purchased a 100e to replace an old, and dying, ASA5510.  The initial setup went smoothly and all traffic was flowing as expected. 

I had to add a second, separate but similar, network for SFTP traffic.  The IP scheme was close but not an exact match.  This part also went smoothly.

I have recently been tasked with configuring a test network for training purposes.  I went about the same process as I did adding in the second network, but ran into a small issue.  Even numbered IP addresses can hit the internet, but odd numbered IP addresses are stopped at the firewall.  For simplicity sake, I opened the ports up to all traffic but still get blocked when using an IP address that has a final octet that ends in an odd number.  For example, X.X.X.132 will work, but X.X.X.45 will not work.  All IP addresses can ping the firewall and internal communication is fine.

Any thoughts or insight would be appreciated.
