Hi 

  This is email is directed to all the subscribers of this mailing list.
I want to thank you and thank you again. Here is the story why. 
For a while my brother's company has been having problems with passing
things through their VPN. Some things would pass and others would time
out: HTTP directory index would pass but the index.html file in that
directory would time out. FTP listing of small directories would pass
but large listings and files wouldn't, small emails would pass but big 
ones didn't etc ... I took me 2-3 weeks to remember where I bumped into 
these issues before, It was in this mailing list. I asked my brother to 
show me firewall log (firewall-1) and what I saw was ICMP type 3 code 4 
(framgment requested but DF set) messages from the VPN peers (if I
remember correctly) which ment that VPN packets trying to pass the WAN
were too big but couldn't be fragmanted. Reducing the MTU to ~1450
solved the problem. I became a hero :) I feel like I owe all my glory
and the solution to the mailing list. So again _THANK YOU_. 







	Paolo
