VPN with SuSE Firewall on CD 2

Hello, I have some trouble with the configuration of VPN wiht SuSE's Firewall: I did as described in the manual ( I did it not only once...) - there is the following message: ------------ Apr 3 10:43:30 fw1 ipsec_setup: (/proc/sys/net/ipv4/conf/eth0/rp_filter = `1', should be 0) -------------------- Is it a serious problem? But pluto starts and adds the connection. When I try to connect from outside the LAN with Win2000 / ipsec-Tool from ebootis.de I can't get any connection to the VPN-Gateway. I get the message "IP-Sicherheit wird verhandelt" and nothing else. "Route Print" shows no route to our LAN... Can somebody give me a hint please?! Martin
