The simplest, though probably not the best based on the numbers you show is two subnets like Router (206.0.98.1) | | |Ep0 206.0.98.10 netmask 255.255.255.128, broadcast 206.0.98.127 -Firewall- (IPFW) |Ep1 206.0.98.129 netmask 255.255.255.128, broadcast 206.0.98.255 | | | ------HUB---------- | | 206.0.98.130 - 206.0.98.254 You could also use a netmask of 206.0.98.192 on this inside net with two external subnets, one a /25 as above and the second another /26 with a netmask of 209.0.98.192. This would give you the address range 193-254 on the inside with the rest on the outside. Routing will be automatic in the first example, you'll need to add a static route for one of the two outside nets in the second case. You may also want to get a copy of _TCP/IP Network Administration_ from O'Reilly.
