Does your DSL router have built in NAT support, and is it enabled?  Some 
of the older SpeedStream routers shipped by some DSL providers have a poor 
implementation of NAT that interacts poorly with other NAT 
implementations, such as the FreeBSD and Linksys NAT code.  When using a 
DSL modem provided by ShenTel in the Shenandoah Valley (in .va.us), I've 
seen TCP connections wedge, close spontaneously, etc, when passing through 
the NAT box...
