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
