Masquerade and NAT

["Patrick Ahler" <patrick@vikus.com>]

Hi,
I am hoping to be able to run IP Masquerade and NAT on the same
firewall/router. ie 192.168.1.1-61 use NAT to translate their internal IP's
to external IP's (a.b.c.1-61), and have a variety of internal hosts on the
same subnet(as the other machines using NAT) using IP masquerading to pass
through the firewall.. ie 192.168.1.62-140 use IPMASQUERADE to translate
their internal ip's to a.b.c.62

Is this possible? If so how? I've found that in order to use IP MASQUERADE
you have to specify a subnet of internal ip's that will use IP MASQUERADE,
but what if I only want to select specific internal ip's that will use it?
Help? Thanks!
