I am now trying to use TL-R600VPN Web Filtering under Behavior Control to limit one client to be able to access only one or two websites. My problem seems to come down to listing the member(s) in the Web Group. I need the client to be able to access abc.def.com.
Using ping on the client, without R600VPN filtering, I can ping abc.def.com and def.com successfully. When I enter abc.def.com as a member in Web Filtering, I cannot ping def.com as expected, but I also cannot ping abc.def.com. If I change Web Filter Member to def.com, I can ping def.com, but not abc.def.com. If I enter *.def.com as member, I cannot ping either abc.def.com or def.com. With this member (*.def.com), abc.def.com name resolves to an IP address without ping response and def.com does not even resolve to IP address without ping response.
If I just disable Web Filtering on the Web Group Filtering tab, I can ping both websites again.
What am I doing wrong to allow client to only access abc.def.com? Thanks.
