Ladies and Gentlemen, I am attempting to connect a FreeBSD server, 8.1-RELEASE to a Juniper J2320 router running the JUNOS operating system. The Juniper router I am connecting to has a public IP address of 1.2.3.4. The provider has not given me a private IP address and has stated it is not needed. The FreeBSD server, has a public IP address of 2.3.4.5 and a private IP address of 6.7.8.9. I am able to create the gif tunnel without any problem. However, the provider I am connecting to has told me there is not a private IP address available for the creation of the private IP tunnel. I will be connecting to private addresses in the 5.6.7.0/24 range on the provider's server. Here is the output of the ifconfig command. gif0: flags=8050<POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1280 tunnel inet 2.3.4.5 --> 1.2.3.4 options=1<ACCEPT_REV_ETHIP_VER> Following are the relevant route table entries. 1.2.3.4/32 2.3.4.5 US 1 798 bge1 5.6.7.0/24 1.2.3.4 UGS 2 192 bge1 Is it possible to connect to the private address on the provider's server without a private IP address? I have done this before, but I have always private IP addresses as well. I do not have racoon running yet. Could this make a difference? Thanks for your help. Jay Hall
