asp.net - Internal Server Error with web.config ipSecurity -
this web.config has tags blocking ipaddress
<configuration> <connectionstrings> ... </connectionstrings> <appsettings> .... </appsettings> <runtime> .... </runtime> <system.webserver> <security> <ipsecurity allowunlisted="false"> <clear/> <add ipaddress="127.0.0.1" allowed="true"/> <add ipaddress="83.116.19.53" allowed="true"/> </ipsecurity> </security> </system.webserver> </configuration>
my intention block other ip except above. above ip address want website accessible . "ipsecurity" tag getting 500 - internal server error , site runs fine without it.
i have made sure "ip , domains restrictions" installed on server. please let me know if missing anything. thank you.
are editing config hand or through iis manager?
