Hi George
No I do not remember changing anything in the IP-Masq test firewall or making
any other changes in that area.
Removed "nameserver 192.168.0.2" on comp B.
I can ping my ISP as follows:
clay@eric:~> ping -c 4 64.24.210.86
PING 64.24.210.86 (64.24.210.86) from 192.168.0.2 : 56(84) bytes of data.

4 packets transmitted, 4 received, 0% loss, time 2998ms
rtt min/avg/max/mdev = 0.189/0.198/0.218/0.018 ms
When I ping "yahoo.com" the connection just hangs until I do a ctrl-alt-c.
the same when I ping 216.126.136.250.

Each time I try your suggestions it seems that I get different answers.
At a loss what to try next.
TIA
