Hi, All!

I have a problem with opening pc from my local network through real ip, with NAT.
I use 3CX PBX which is installed on my server Windows Server 2008, and have FQDN from noip.com "myname.noip.com" and configured src-nat and dst-nat on RB 750. When I try to access my server from outside there is no problem, everything works fine, but if I try access server from Local Lan (connected to eth2) with outside FQDN or External IP I receive "can't reach this page" or simmilar from diffrent browsers.
I make static DNS record in my RB, which forward to internal server IP, but is there other decision? And is this problem from my configuration or from ISP?

I have RB 750 with WAN on eth1 and LAN on eth2.

NAT configuration:

chain=srcnat action=src-nat to-addresses=84.xxx.xxx.xxx src-address=192.168.1.0/24
out-interface=ether1 log=no log-prefix=""

chain=dstnat action=dst-nat to-addresses=192.168.1.250 protocol=tcp
dst-address=84.xxx.xxx.xxx
dst-port=80,443,3389,5000,5001,5060,5061,5090,5223,5228-5230,2195,2196 log=no
log-prefix=""


I try to change ARP option on eth2 to arp-proxy, but nothing change.

Can someone help me? Thank You

You want thing called hairpin NAT.

Thank You, Sob!
It works great for me.
