I'm wondering if the idea of using a monowall box to act as a
replacement for something like a Cisco 1600 is possible. I have tried
many different configurations to get mono running between my external
network and the internal. For various reasons (none of which I can solve
with the political corporate climate) I have to look for a different
solution. I need to be able to firewall a connection between a Sprint T1
and an ethernet network. 

Has anyone had any experience using a PCI interface to an ADTRAN csu/dsu
(model tsu120) using monowall?  Is such a thing possible?

Getting desperate here. I might have to go buy an ethernet non-ip
filtering bridge. At 10,000.00 for a checkpoint device I'd rather gnaw
my foot off.
