We are using ASL 5.017 and Windows XP Pro (with KB818043 NAT-T bugfix).
L2TP works fine if we directly connect to the firewall with a XP client. If we have a netgear router RP114 (firmware V3.26) sitting inbetween the client and the firewall the L2TP connection fails. [:(]
Before installing KB818043 on the clients we did not see anything in the IPSec VPN Logs. After installing the patch we get some logging but it still does not work.
We get the following messages in the log (full logfile attached):
2004:08:05-23:09:17 (none) pluto[1216]: "S_VPN_Zugang_1"[6] 62.52.32.62:4500 #6: cannot respond to IPsec SA request because no connection is known for 80.132.11.33/32===172.16.0.2:4500:17/1701...62.52.32.62:4500:17/%any{}

Anybody any ideas?
