We have recently had to increase the amount of IP addresses that we use internally on our network. We went from a class C to a class B subnet and everything is working fine. We did run into some issues with Border Manager 3.6 and the NAT not working properly. I found, thanks to these forums, that cause was due to supernetting. Border Manager becomes an end node and will not forward packets. My question now is. We are installing Border Manager 3.8 on a server with Netware 6.0 with the latest service packs. What is the largest mask that I can use to keep NAT working properly? Is the largest mask still going to be 255.255.255.0? How do I go about setting this up to support more addresses than the Class C subnet? Would Netware 6.5 be better to go to?

Thanks in advance for any information.
