we have a 2851 router which interconnect our local network to public network. we recieve our internet on interface e0/1 and e0/0 restricted to our lan as below configs
int e0/0 192.168.10.125220.127.116.11
ip nat inside
our users from internet can access our web server
but we cant access our web server with public address x.x.x.245 or
equivalent domain name and we can only access it with local address 192.168.10.9 in our lan.
how can we access our web server with public FDQN domain name or public ip address ?
You need something called a loop back NAT when you want to access your internal server through public ip.....
This is because here you hit the gateway and get back your network since the server is hosted in your network...Try to find out if there is a way to create a NAT policy on your router...so that when you try to access this server with a public ip it is NAT to the private ip of the server...
In regards to "we can only access it with local address 192.168.10.9 in our lan. how can we access our web server with public FDQN domain name or public ip address" if that still holds true. I have seen this issue when I.T. makes thier domain a .com instead of a .local. Anyhow if you have internal DNS server which most companies have, and is mandatory for domains, I would add this domain to DNS create a mirror image of all external DNS records except for the DNS record for the Host A for the website. I would point the Host A for SomeSite.com to my LAN IP.
