Hi to all!!! I need some help to configure my 3 servers... The three servers have public IP, and I need to see them via a private IP located in 172.20.x.x. I configured a gre(4) interface on servers 1 and 2 to tunnel (and I need help for Server 3).
On server1:
On server2:
1 and 2 can communicate via the tunnel...
On server3 I need a configuration like:
(2 and 3 have to be isolated from each other). But the server1 cannot accept... Any suggestion? Can I create an alias on server1 with same IP and different endpoint? Thanks to all.
On server1:
Code:
gre0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1476
options=80000<LINKSTATE>
tunnel inet a.b.c.d --> e.f.g.h
inet 172.20.1.1 --> 172.20.1.2 netmask 0xffffff00
nd6 options=4b<PERFORMNUD,ACCEPT_RTADV,IFDISABLED,NO_RADR>
