Can anyone tell how how to setup up the Cisco 877 to allow only one external ip xxx.xxx.xxx.xxx to access my server ?
My Server PC connects to the internet through the Cisco 877 and it has an internal ip 10.10.10.2 and also an SQL Server
My other PC on a different location has a static IP 220.127.116.11 (it's an example)
What i want is only to allow ONLY my other PC with the IP 18.104.22.168 to access my Server and only the SQL Server port.
IOW, if anyone tries to access my server without having the IP 22.214.171.124 block the access.
Thank you in advance.
