Hi All, I am using laptop, FreeBSD 7.1 connecting to two ISPs (wlan and ppp) and I have IPv6 addresses. 'netstat -rn' says there is only one default gateway (for example wlan's default gateway). My problem is the following: If I ping the ppp tunnel from an other computer, my laptop recieves the ICMP6 echo request over the ppp tunnel, but it answers over the wlan interface. I read some similar posts (only ipv4) about forwarding with IPFW, but I was unable to solve my problem until now. I built a kernel with the following options: options IPFIREWALL options IPFIREWALL_VERBOSE options IPFIREWALL_DEFAULT_TO_ACCEPT options IPFIREWALL_FORWARD and put these lines to my rc.conf firewall_enable="YES" firewall_type="open" as the handbook says. I use the following command as root: ipfw add 101 fwd pppgateway ipv6 from pppaddress to any (pppgateway and pppaddress ipv6 addresses) It throws "getsockopt(IP_FW_ADD): Invalid argument" error! I have tried to set the following variables but the problem is still the same. sysctl -w net.inet.ip.forwarding=1 and sysctl -w net.inet6.ip6.forwarding=1 Can anybody help me? -- View this message in context: http://www.nabble.com/FreeBSD-7.1-IPv6-multihoming-problem-tp22800054p22800054.html Sent from the freebsd-ipfw mailing list archive at Nabble.com.
