Hello, I'm trying to establish a VPN tunnel over internet, I read a http://www.freebsd.org/doc/en/books/handbook/ipsec.html on how to set it up, I'm some what strangeling if my setup will work at all. i have box #1 that have 1 primary IP, which is private IP but in front of my box, I have a device that translate a public IP address into private IP, so "technicaly" its a public IP not a private, yet system sees it as private, yet my box #2 has interface with real public ip and another interface with private ip, i created GIF0 interface, yet i can't ping private range on other box. box#1 fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=8<VLAN_MTU> ether 00:0f:fe:aa:f4:61 inet 192.168.1.251 netmask 0xffffff00 broadcast 192.168.1.255 inet 172.16.172.16 netmask 0xffffffff broadcast 172.16.172.16 media: Ethernet autoselect (100baseTX <full-duplex>) status: active plip0: flags=108810<POINTOPOINT,SIMPLEX,MULTICAST,NEEDSGIANT> metric 0 mtu 1500 lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3 inet6 ::1 prefixlen 128 inet 127.0.0.1 netmask 0xff000000 gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1280 tunnel inet 38.96.123.42 --> 74.2.252.194 inet 192.168.1.251 --> 192.168.2.252 netmask 0xffffffff alexus@jot ~ 503$ netstat -rn | grep gif0 192.168.2.252 192.168.1.251 UH 0 15 gif0 alexus@jot ~ 504$ box#2 su-3.2# ifconfig dc0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=8<VLAN_MTU> ether 00:1a:70:10:e3:89 inet 74.2.252.194 netmask 0xfffffff8 broadcast 74.2.252.199 media: Ethernet autoselect (100baseTX) status: active fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=8<VLAN_MTU> ether 00:13:20:09:53:31 inet 192.168.2.252 netmask 0xffffff00 broadcast 192.168.2.255 media: Ethernet autoselect (100baseTX <full-duplex>) status: active lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384 inet 127.0.0.1 netmask 0xff000000 gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1280 tunnel inet 74.2.252.194 --> 38.96.132.42 inet 192.168.2.252 --> 192.168.1.251 netmask 0xffffffff su-3.2# netstat -rn | grep gif0 192.168.1.251 192.168.2.252 UH 0 602 gif0 su-3.2# any suggestions are welcome, thanks! -- http://alexus.org/
