>  have a alias on de2 of xxx.xxx.42.208 I can SSh to that address but can't ping it. I get can't  assign requested address. Netmask is 255.255.255.248. Other port ping just fine XXX.XXX.41.1 on de2.  Any help

Are both IP addresses on the same subnet? If so, you'll have to use
255.255.255.255 as the netmask for the alias. See the ifconfig(8) manpage.
