Re: (ASCEND) mail attachment problem

Hi , 

This could be the MTU size misconfiguration  for the PPP. I wonder what
equipment do you use to connect to your upstream service Provider and also
terminating equipment used by your service provider?. Besides that what
type of equipment are u connecting your 56K leased line to the LAN.. ? More
details will enable me to rule out whether it is MTU/MRU problems. .. 
Cheerios .
