I've had a problem whenever I upgrade my BEFSR41 router to any other firmware version other than 1.04.8. I need to connect to various customer's sites using VPN. For the most part I use PPTP but in 2 cases I need to use L2TP to gain access to their networks. Both of these sites have a Netscreen firewall. I am an authorised user at both sites. My connection works perfect as long as I do not upgrade my router to any other version greater than 1.04.8 of the router. As soon as I attempt 1.05 or 1.06 (as found in this site), my L2TP connection no longer works and I have to restore the 1.04.8! This is frustrating. Anyone else encounter this problem? Thanks.
