Or, assuming that it hands out a DHCP address with a default gateway 
(and the modem/NAT unit is acting as the default gateway):

a) Look for the default route (indicated as the line starting with 
0.0.0.0 for IPv4)

# route -n
0.0.0.0         192.168.0.1   0.0.0.0         UG

b) Look at the dhclient.leases file.  This can be hit or miss, depending 
on whether you can find the proper section.  Other distros put it in a 
slightly different location.

/var/lib/dhclient/dhclient.leases
lease {
   interface "eth1";
   fixed-address 192.168.1.186;
   option subnet-mask 255.255.255.0;
   option routers 192.168.1.1;
   option dhcp-lease-time 3600;
   option dhcp-message-type 5;
   option domain-name-servers 192.168.1.1;
   option dhcp-server-identifier 192.168.1.1;
   option domain-name "lan.example.org";
   renew 3 2009/4/8 11:57:39;
   rebind 3 2009/4/8 12:21:03;
   expire 3 2009/4/8 12:28:33;
}

c) Or the "ip" command.

$ ip route list
default via 192.168.1.1 dev eth0  proto static

(Guessing about IP addresses gets harder in a few years once IPv6 
finally goes mainstream.)
