OK,

At the suggestion of Brian, I turned on TCP/IP logging with PPP and here is
some of the output of the log.

It looks to me that I can only recieve TCP traffic.  UDP and ICMP seem to be
getting blocked on the way in somewhere.

If I try an ftp 151.141.27.40 (linux machine at school):

Communication there looks ok but the connection is very sluggish compared to
what I get from windows on  the same machine/same ISP.  You can see the TCP
traffic going in and outbound.

Try nslookup:

Apr  8 20:12:55 vertex ppp[202]: tun0: TCP/IP: OUT UDP:
206.107.119.134:1036 ---> 206.107.119.4:53
Apr  8 20:13:00 vertex ppp[202]: tun0: TCP/IP: OUT UDP:
206.107.119.134:1037 ---> 206.107.119.4:53
Apr  8 20:13:10 vertex ppp[202]: tun0: TCP/IP: OUT UDP:
206.107.119.134:1038 ---> 206.107.119.4:53
Apr  8 20:13:30 vertex ppp[202]: tun0: TCP/IP: OUT UDP:
206.107.119.134:1039 ---> 206.107.119.4:53

The IP adddress of my DNS is correct.  The request times out, nowhere do I
see anything incoming from 206.107.119.4 and for that matter I do ot see ANY
inbound UDP packets in the entire logfile.  That is kind of interesting....

---------------------------------------------------------------------------
I try ping 151.141.27.40.  I can ftp there I should be able to ping it.
Ping gives no response, the log shows

Apr  8 20:13:56 vertex ppp[202]: tun0: TCP/IP: OUT ICMP:
206.107.119.134:8 ---> 151.141.27.40:8
Apr  8 20:14:11 vertex last message repeated 15 times

Also nowhere in the log do I see inbound ICMP packets.  VERY
interesting......

All suggestions are welcomed.  This seems to be getting stranger to me.....
