Need Failover Help
-
Hi,
I am having trouble with Multi-WAN and failover. When all the lines are online everything is just great fast speeds all around. However when 1 or more lines go down (I have 4 lines load balanced), internet browsing becomes borderline unusable. Alot of sites just hang at "waiting for" or "connecting to" which usually indicates a DNS issue. Add to that fact that once the site is in the DNS cache it runs perfectly fine. Also other services not reliant on DNS such as torrents failover just fine. Its only DNS reliant services that just become extremely unusable and queries timeout alot.
Now I run my own dns forwarders behind my network. I am not using PFsense DNS forwarder at all. My servers forward and do lookups on google DNS servers (8.8.8.8 and 8.8.4.4) so is there any reason why DNS queries wouldn't load balance out like any other traffic. It should be noted that even trying to set the local machines DNS lookup server to googles or any other external DNS server doesn't fix the problem site just hang on dns lookups. :(
Can I get some help resolving this issue? Thanks.
