Hi Orlando,

Thanks for the reply.

This is the case, and it happens for all traffic, not just a ping.  But 
it works on EVERYONE ELSE's system, just not the DSL ISP!

One thing I just found, by watching a TCPDUMP during an external ping: I 
get a reply from my (t1) reply packet, saying "Admin Filter Prohibited".

I did the following:
route add -net 64.65.0.0 netmask 255.255.0.0 gw 64.65.206.1 eth1 

Which works, as long as the source IP within the DSL network is within 
64.65.x.x.  However, I do have a DSL line that is on a different range 
(yet the same ISP).  I can make it work by doing the above command, 
specifying that IP for the first set of numbers.  But honestly, should I 
have to do all this work, trying to figure all the IP addresses of my 
DSL ISP just to make their networks work?  It seems like there must be 
another way.

Bob
