web proxy blocked certain website automatically

HI:

I just cant figure it how and why lis.deped.gov.ph was blocked when mikrotik webproxy is enable.

I got this error:
ERROR: Gateway Timeout
While trying to retrieve the URL http://lis.deped.gov.ph:
Connection refused

it works fine without proxy.
lis.deped.gov.ph got an ip of 103.24.16.10 and 103.24.16.50
Placing the ip in Address list is no good too:

/ip firewall address-list
add address=103.24.16.10 list=LIS1
add address=103.24.16.50 list=LIS2
/ip firewall filter
add chain=forward protocol=tcp src-address-list=LIS1
add chain=forward dst-address-list=LIS1 protocol=tcp
add chain=forward protocol=tcp src-address-list=LIS2
add chain=forward dst-address-list=LIS2 protocol=tcp

Thanks for your time.

PS: im using Mikrotik 1100x2AH

I already found the solution :slight_smile:

/ip firewall address-list
add address=103.24.16.10 list=LIS1
add address=103.24.16.50 list=LIS2
/ip firewall nat
add chain=dstnat dst-address-list=LIS1
add chain=dstnat dst-address-list=LIS2

Place before the web proxy Nat. I’ll be happy to see if you have other suggestion.
