FVS318N DNS drama...
This is driving me nuts... and by the looks of things, has been a problem with these firewalls for VERY long time. I have two of these things... and they both exhibit the SAME behavior. Latest fi...
Hi BrianL,
First I should appologize for my frustration... I had been trying to resolve this issue for roughly 4 hours...
After more than 5 restarts of both the cable modem and the firewall, it finally began passing DNS requests from the LAN to the WAN and back again. I had cranked up logging in an effort to determine what was taking place and / or failing. The logs of the firewall were claiming the DNS querry traffic was indeed being passed but since it's UDP (non hand-shaked traffic) the only thing I can think of that must have been happing were the arp tables were still invalid causing the traffice to never reach its destination. This firewall was replacing an antique Sonic wall so naturally the MAC addresses had changed. And yes... the hosts behind the firewall had indeed been listed as shown above, part of the initial configuration I had done right from the start. This unit is my second with the first one having been in use for some time... consequently I do have some experience with these devices. :-)
Hi Digithead,
Good thing it worked again, but this behavior is not normal. Can you confirm if there are any firewall rules active under LAN/WAN rules?
Kind regards,

Actually yes, there are now. I had not setup any at all until I got the DNS traffic working correctly. Of course the default outgoing rule never shows... and it's my understanding that it shouldn't anyway. Is that correct? (I hope that's correct, because neither of the two FVS318N's that I have show the default outgoing rule)
Hi Digithead,
Yes that's true. I believe there is a drop down button at the top of the LAN/WAN rules page where you can set the default outbound policy to allow or block always. Going back to the main problem you reported, if it persists again, I suggest you contact our support team to create a ticket and checked by one of our Engineers.
Kind regards,
