Thanks John. These addresses are AWS ranges so in theory we may be routing traffic to another site in those ranges however I think this is by far the best answer. Ideally we would be able to get the plex list of ip addresses. On a separate note, how do you find the AC68? Are you using an updated firmware such as : https://github.com/RMerl/asuswrt-merlin/blob/master/release/src/router/rc/firewall.c Thanks again for your help.
