Hi Paul, I worked for a VPN company in the past. Check the MTU size. I think the packet may not be making it thru both the IPSec encapsulation and the PPPoe encapsulation. The max MTU size is 1524. IPSec adds overhead to the IP packet (new header and extra data) and then PPPoe adds even more. It works fine for small packets (ping and etc), but when you get to larger packets they get dropped. ----- Original Message ----- From: "Paul Gaskin" <paul () midwesttechnologies com> To: <security-basics () securityfocus com> Sent: Friday, January 17, 2003 3:29 PM 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
