Dear @ahmed_bantwa,
i have load balancer tp link tl-r470t+ having an issue is that some of website is not working its always shown that this website has been blocked contact to your administrator
please help me becasue many website are been blocked
Is the TL-R470T+ connected to your ISP box for the Internet? If you remove the TL-R470T+ and hardwire the end-device directly to the ISP box via cable, are you able to access those websites properly? Please confirm that the websites are reachable when the TL-R470T+ is bypassed before we try further troubleshooting on the TL-R470T+.
If those websites are not accessible no matter whether the TL-R470T+ is connected, it's suggested to contact the ISP for checking.
