I have a specific routing question for Vyatta and Mikrotik RouterOS experts.
I have many servers in 2 datacenters:
Vyatta Core 6.1
16 public IP addresses, provided by datacenter host, all 16 IP configured on eth0 adapter of Vyatta Core
Servers are behind NAT, with multiple 1-to-1 port mapping for each web service
3 x class-C public IP ranges + 1 x routing segment /30
The routing segment is:
126.96.36.199/30 on my RouterOS side
188.8.131.52/30 on my ISP provider's side
All other C-Class segments are then configured on my Mikrotik RouterOS and are used without NAT locally.
What I want to do?
In DC-2 I don't have a lot of room, and main servers are in DC-1, so I would like to use
IP addresses from DC-2 on servers in DC-1 location.
As far as I know, this can be established by using Ethernet-over-IP Tunnel, but I have tried and failed. Actually, I am lost in configurations on both sides, what I need to configure exactly to connect that EoIP Tunnel and to use IP addresses from DC2 in DC1 servers.
Some instructions would be appreciated.
For REALLY EXACT (and working, of course) instructions I can promise additional 500 points!
