DD-WRT routing my DynDNS

I use dyndns to use my local linux server with my dynamic IP address assigned with Baja Broadband. The problem was that after I upgraded my router with DD-WRT, my benengel.dyndns.org was not looping back to my web server thru my router. Google helped me find a page with the solution:

In Administration->Commands, enter the following:

iptables -t nat -I POSTROUTING -s 192.168.3.0/24 -j SNAT --to-source `nvram get wan_ipaddr`

Run the command and then save it as a startup command so it doesn't go away after the next reboot.
