I use OpenDNS for DNS but I have a couple of different IP addresses with different filtering categories.
I have different masquerade rules configured for different internal VLANs such that most appear to the outside world on one particular IP address but there is one VLAN that appears on a different IP address to the rest. (My 'guest' VLAN).
This has different (more) categories blocked on my OpenDNS dashboard.
The problem I'm having at the moment is that I'm not seeing any DNS requests from that network on my dashboard (and none of the categories I've selected are being filtered).
I think the masquerade rule is working correctly because using sites like ipchicken.com and whatsmyip.org from a client device on that VLAN gives the correct public IP.
I have a hotspot on that VLAN however and am wondering if this is causing the DNS to do something silly.
Are there any sections of my config I can post in order to get some help troubleshooting?
Note I'm on an earlier version of ROS at the moment and the export compact command isn't available - just let me know what you want me to post and I will!
I should note that DHCP for the VLAN is initially done from a W2K3 server on my LAN but then the hotspot takes over, although as far as I can tell the client device still gets the DNS servers from the option on the W2K3 box.
It was initially:
<LAN IP of RB750>
I've removed the LAN IP of the RB750 from the list of DNS servers for that VLAN's scope and cleared the DNS cache of the RB750 and the client device to no avail - still no requests seen on OpenDNS and still categories that should be blocked are available.
My other VLANs seem to be getting blocked from restricted categories there without any issue.
Update: Looks like this is related to the NAT rules for the hotspot. No idea how to fix this without breaking the hotspot?
