How to add swap memory to Netgate SG-3100

How do you add a swap file for memory in the Netgate SG-3100 ? I would of liked to have added more physical memory but you can not on this box I was messing around with the pfblocker geoip and it keeps saying I do not have enough memory when I try to block countries.

Adding a swap file for any Linux or FreeBSD host is easy.

    add this line to the file /etc/fstab
    md99 none swap sw,file=/pagefile.bin 0 0

    create a blank file of size 1 GB
    dd if=/dev/zero of=/pagefile.bin bs=4096 count=262144

    enable swap (or just reboot as a test):
    /sbin/swapon -a

    verify swap is enabled
    /usr/sbin/swapinfo

You don't need more memory for GeoIP. Just increase the pfSense > System > Advanced > Firewall & NAT > Firewall Maximum Table Entries > 2000000

DNSBL on the other hand needs more memory depending on the number of domains added and if wildcard blocking is enabled (The TLD option).
