Here are a few things to check:
1. Only 1 IP address assigned to a NIC on the GNAT Box, in the same logical network as other IP addresses (aliases or real) can have the real netmask of the network/subnet. This means if you add aliases in the same subnet they must all have 255.255.255.255 netmasks. Example: EXT: 199.120.225.2/255.255.255.0 Aliases: Ext: 199.120.225.3/255.255.255.255 Ext: 199.120.225.10/255.255.255.255 Now if you had the same thing and added a new alias from a different network it would be: EXT: 199.120.225.2/255.255.255.0 Alias: EXT: 199.120.225.3/255.255.255.255 EXT: 198.1.200.5/255.255.255.0 <-- A real subnet mask here now EXT: 198.1.200.9/255.255.255.255 <-- Notice the mask on the additional entry 2. Your change to the EXT NIC may have caused the problem. Since all the IP addresses assigned to a NIC are stored in a linked list. Nearly always the real IP address is the first element in this list, since it must exist first before aliases can be added. If you change it the element is deleted and added back to the list (since all IP addresses assigned to the NIC are treated alike) at the end. So to resolve this, on the alias screen do a save. This will delete the alias list and rebuild it, adding the aliases in the link list after the real IP address. If this doesn't unclog things you might also need a reboot. Changing the IP address or mask on the network information screen sometimes requires a reboot since many things are based and keyed from this information.
