I used the following syntax to add an IP address (10.0.0.1) to the restrited IIS 7.5 section for the whole server :
appcmd.exe set config -section:system.webServer/security/ipSecurity /+[ipAddress='10.0.0.1',allowed='False'] /commit:apphost
Very nice so far. The restriction is shown in the blacklist in IIS 7.5.
Now I want to delete this one (10.0.0.1) - and only this one - to give it access to the webserver again. I cannot find the right syntax for it and using the above command with "allowed:'True'" does not work, because the IP address is already in the list as "allowed:'False'".
Can anyone provide me the right syntax to delete one IP address from the blacklist ?
