problem with FreeS/WAN IPsec
 

hi

I try to setup FreeS/WAN IPsec
on linux SuSE 8.2,
and if I do restart I get this message :

# /etc/init.d/ipsec restart
ipsec_setup: Stopping FreeS/WAN IPsec... done
ipsec_setup: Starting FreeS/WAN IPsec 1.99...
ipsec_setup: ipsec ipsec_3des ipsec_md5 ipsec_sha1
ipsec_setup: WARNING: eth0 has route filtering turned on, KLIPS may not work
ipsec_setup: (/proc/sys/net/ipv4/conf/eth0/rp_filter = `1', should be 0)
ipsec_setup: done

I don't understand, what's wrong with:
/proc/sys/net/ipv4/conf/eth0/rp_filter = `1'
and where can I change it.

in ipsec.conf I can't find this path.

kind regards
cccc
