if the Server in same IP address of Local network ? how is external party Access using IP or DNS ?

Do you DNS Entry with Local IP address for local user to access

 

example : external bb.com x.x.x.x - natter to 10.10.10.1 IP address

same DNS entry required local DNS bb.com 10.10.10.1

Yes, as already mentioned previously you can use different DNS entry.

From the outside - server.domain.name = 1.1.1.1 and from the inside network - server.domain.name = 192.168.1.2

my website is not in local but use local services example : my global IP 1.1.1.1 local server 192.168.1.2 i have Nat 1.1.1.1:80  to 192.168.1.2:80 and from outside it works website can tack information from my server  but from local : 192.168.1.4 i try to connect 1.1.1.1:80 and it is not working.

@shotalezhava 

I would expect it to be a nat problem. Can you not connect directly to 192.168.1.2:80 instead of the public IP address?

From local if connect to 192.168.1.2:80 it is working but it is like stream and website gets stream from my local server so i can not change IP address on my website if i will change it it will not work from outside, if i will give domain to this server and configure local dns that this domain is on 192.168.1.2 it will work?

Yes, as already mentioned previously you can use different DNS entry.

From the outside - server.domain.name = 1.1.1.1 and from the inside network - server.domain.name = 192.168.1.2

Aren't there any other solutions?

You could use NAT reflection, here is an example for ASA - I imagine it's the same logic when configuring using FTD.
