Luckily, this is configurable in Linux. You can set it in the kernel:

/usr/src/linux/net/ipv4/tcp_ipv4.c

/*
 * This array holds the first and last local port number.
 * For high-usage systems, use sysctl to change this to
 * 32768-61000
 */
 int sysctl_local_port_range[2] = { 1024, 4999 };
 Or via the proc interface at any time (i.e. in the network startup
script):
 /proc/sys/net/ipv4/ip_local_port_range
