I found that bug, too. You may have missed one of my later emails where
I state that I have an MTU of 1400 when I am connected.  Below is output
from ifconfig when I'm connected:

ppp0      Link encap:Point-to-Point Protocol  
          inet addr:192.168.4.107  P-t-P:192.168.4.107
Mask:255.255.255.255
          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1400  Metric:1
          RX packets:11 errors:0 dropped:0 overruns:0 frame:0
          TX packets:11 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:3 
          RX bytes:291 (291.0 B)  TX bytes:228 (228.0 B)




I did try your suggestion of changing the MTU to 1412, but it had no
effect.  I run Hardy (Ubuntu 8.04) on another of my computers and I have
noticed that the inet address and the P-t-P address are different when
I'm connected to a VPN with it. Could that be a source of the issue?
