OK, here's an update...  

The reason that the xxx.xxx.246.0/24 was working is that it's gateway was set 
to xxx.xxx.240.1 and the xxx.xxx.248.0/24 was set to xxx.xxx.248.1 I changed 
the gateway to xxx.xxx.240.1 and will try it tonight and let you know how I 
fare this time.

Just one other question before I do all this.  It pertains to the firewall 
rules.  Does monowall process the rules from top to bottom or bottom to top?
