Quoting Marcelo Souza <mpsouza@centroin.com.br>:
I'm still having trouble with some ISDN users, that cannot send e-mails with attached files. The common thing among these users is that they're using a TELES ISDN Winmodem (www.teles.de), and I have may of then, since it's being sold by the local telco. Someone already told me to reduce the MTU in the ARC, but it does not solve the problem.
MTU could be your problem if fragmentation of data is required. What you are saying here is that your clients cannot send emails with attachments, which basically tells me that the client is sending the data to the router (NAS) which then forwards the same to the mail server which may ask you to fragment the data. The question is where did you setup the MTU change? On radius? on the default user? or on the client? You see in 4.1.59 if this is a MTU problem - then you have to do the following. Remove all the MTU values that you send from radius Set the default user on the HiPer arc to a mtu value of 576 (to start) Do not set any specific MTU for the user on the client side. If this does not work, then info on your connection to the mail server is necessary, to understand the path MTU. By any chance can your users send email using hotmail or other email with attachments using the same modem? -V
The FW version is:
DSP - 2.1.9 ARC - 4.1.59
Any tip?
