Hello All,
I have:
Private Net 1 Firewall 1 Firewall 2 Private Net 2
--------------- ------------ ------------ ---------------
| 10.1.0.0/24 |----| FBSD 4.7 |--//--| FBSD 4.7 |----| 10.2.0.0/24 |
--------------- ------------ ------------ ---------------
|______tunnel______|
I want to configure tunnel between "Private Net 1" and "Private Net 2"
and
can not get tunnel to work when Public IP of "Firewall 1" and "Firewall
2" are
from same subnet. If public IPs of my firewalls are from different
subnets all works fine.
On "Firewall 1" I do:
# ifconfig gif0 create
# gifconfig gif0 x.y.z.1 x.y.z.2
# ifconfig gif0 inet 10.255.255.1 10.255.255.2 netmask 255.255.255.252
# route add -net 10.2.0.0/24 10.255.255.2
On "Firewall 2" I do:
# ifconfig gif0 create
# gifconfig gif0 x.y.z.2 x.y.z.1
# ifconfig gif0 inet 10.255.255.2 10.255.255.1 netmask 255.255.255.252
# route add -net 10.1.0.0/24 10.255.255.1
Is there any way to get this to work?
Thanks in advance
