That's up to you. The most commonly used subnet is 192.168.0.0/24.
When you buy ready made devices, if at all pre-configured that's what they 
usually are.

In all likelyhood you don't have a reason to limit the number of IP's that you 
have. So you'll give yourself 256 addresses in 192.168.0.0 or 192.168.1.0.

The very first IP is reserved to represent the network. The 2nd is usually 
reserved for the gateway. While the last one is the broadcast address. 

The gateway can be any IP but not the first and last. 

On the NAT side that would mean .0 and .255 is reserved and you could make the 
int_if be 192.168.x.1. I have a lot of machines and have arranged addresses 
for different use. 

ext_if will be whatever IP your ISP gives you.
