Natting from local server to remote server

[mohammed asif suleman]

Hi all,

Please Can any one help me understand this concept...

Let me show you the scenario

one MPLS connection from ISP coming to my router and from my router to DMZ servers

i have to connect to the Remote server to my DMZ server

The ISP gave me the details of BGP to configure

now what i have to do to Route my private network to the remote servers...

They gave me source and destination ip address to NAT

                               now i am confused to which ip should i nat as inside to outside  and outside to inside

The ip 10.16.21.206 is their test server IP address, I spoke to them but they are reluctent to create tunnels...

Source IP Address	Destination IP Address	Service	Action
10.11.19.43	10.16.21.206	5775/tcp	allow

my server IP : 10.10.10.28

my inside global ip : 172.18.4.130

my outside global ip is 172.18.4.129

the network diagram is as follows

                                      

please help me to configure this

Thank you very much Raju,

The above information you provided is very detailed and exteremly helpful.....

The acl is in place as i am allowing only one ip 10.11.19.51 to 10.16.21.206

i can see the output in ip nat translations  as you specified when i ping to remote server

the ping to remote server failed(i have to check with remote people to allow the ping)

i just changed the advertised statement in BGP to network 10.16.21.206/32

i can see the advertised result     

Show ip bgp neighbor 172.18.4.129 advertised-routes

  Network               Next Hop            Metric LocPrf Weight Path

*> 10.16.21.206/32  0.0.0.0                  0         32768 i

now i think all will work fine......thanks for your interest in solving the problem
