Morgan' Cc: '[EMAIL PROTECTED]' Subject: RE: VPN & PPPoE Is there a sure fire way to come up with a good MTU speed? We used one in the Microsoft Knowledge Base. and came up with an MTU of 1366 and this didn't seem to do the trick. Also, We had a concern with setting the MTU really low. How is this going to effect the way other files get transferred? Will setting the MTU lower effect the speed of the DSL (surfing the web, downloading files)?

The solution was to kick the interface (pppoe facing) MTU down to the 1280 range. This was after some experimentation. Play around with the MTU and you should be able to get it to work. If you have a sniffer handy on the client machine, watch to see how much fragmentation is occuring on the interface. Lots of fragmentation seemed to break IPSEC for us. -----Original Message----- From: Paul Gaskin [mailto:[EMAIL PROTECTED]] Sent: Friday, January 17, 2003 4:29 PM To: '[EMAIL PROTECTED]' Subject: VPN & PPPoE I am new to the list and I'm not sure if this even falls into this category but I'm getting desperate! We have set up a VPN and it seems to work fine everyone can log on and move around the network and send and receive email. One person though... on a DSL using PPPoE can not send e-mail. we have tried everything... has anyone run into this problem? the user is on a Windows XP laptop connected to a Linksys wireless router (Using PPPoE). and Outlook for E-mail. Any help would be greatly appreciated Thanks in advance Paul
