Dear Gerhard After receive you last e-mail, I make two experiments.
1. I try to establish a tunnel mode connection between the 2 hosts like this: conn hp100-hp200 [EMAIL PROTECTED] leftrsasigkey=0sAQO... leftsubnet=2001:250:f006:2::1/64 [EMAIL PROTECTED] rightrsasigkey=0sAQO... right=2001:250:f006:1::451 rightsubnet=2001:250:f006:3::1/64 keyingtries=2 ikelifetime=30m keylife=10m rekeymargin=30s rekeyfuzz=1% authby=rsasig type=tunnel connaddrfamily=ipv6 auto=add Then I start the connection of "hp100-hp200", it's still the same error. 2. I remove the IPV4 address of every NIC, delete FreeS/WAN on two hosts and make FreeS/WAN with IPV6 Patch again. Then I verify the FreeS/WAN: [EMAIL PROTECTED] lorry]# ipsec verify Checking for KLIPS support in kernel [OK] Checking for RSA private key (/etc/ipsec.secrets) [OK] Checking that pluto is running [OK] Checking if IPchains has port 500 hole (all) accepted [OK] Checking if IPchains has port 500 hole (default) accepted [OK] Checking if IPchains has port 500 hole (eth0) accepted [OK] Checking if IPchains has port 500 hole (eth1) accepted [OK] Checking if IPchains has port 500 hole (ipsec0) accepted [OK] Checking if IPchains has port 500 hole (lo) accepted [OK] DNS checks. Looking for forward key for HP100.ntl.ict.ac.cn [OK] Does the machine have at least one non-private address [failed] If I start the connection of "hp100-hp200" brutely, it will display an error. [EMAIL PROTECTED] lorry]# ipsec auto --up hp100-hp200 022 "hp100-hp200" we have no ipsecN interface for either end of this connection I hear that IPV6 Patch doesn't utilize the virtual IPSEC interface like in IPv4. But how to explain the phenomena? I feel too upset to continue. Can you tell me which version of Suse linux you use and your recommend configuration of kenerl, network, route and FreeS/WAN. Can you find something wrong with my configuration from my last mail? Please help me. Thanks in advance.
