You appear to be running an open recursive resolver at IP address 103. how do i disable the recursive queries ability so that external attackers cant use it? does disabling ALLOW REMOTE REQUESTS prevent recursive querries? thanks. IP Public Check. What is the purpose of mangling? Related to failover??? Oh I see, the MT document has mangling but this is very confusing. Thanks again, I can now be fairly confident that if the recursive route isn't reachable the router will failover from WAN to the other. Good evening all, I am about to configure Recursive Failover on my CCR with dual WAN. Topology: MikroTik. 2. I have currently 3 nested recursive route, It is perhaps too much I am looking to replace my recursive routing with a a script called by Netwatch or just scheduled. mrz MikroTik Support Posts: 7169 Joined: Wed Feb 07, 2007 11:45 am On the Office mikrotik I create a Src nat rule so that the 1702 vlan uses the 2nd public. But it can be dangerous, as you can cause loops. x you could do the same for a recursive gateway, if you set the gateway route "scope=10" then it could be found by a recursive route with "target-scope=10". Having a second recursive, eliminates the issue where the connectivity to the ISP is fine, access to the WWW is fine, but the DNS site itself is down. ip bridge-wan, Also, while Mikrotik /everyone seems to use Google/etc DNS as the "host to check", there is a side-effect since traffic to 8. It is necessary to restrict a set of routes that I cant express my feelings how much I hate Mikrotik for doing such stuff, which makes everything so overly complicated!! For everyone who wants/needs to cheat, this works: Single WAN-Check: single-check. Failover with recursive routing stays on backup connection. Hi guys, Finally I have failover with On that route, set scope to 64 and target scope also 64. You could still ping but it was intermittent with latency spikes. X that participated in an attack against a customer of ours, generating large UDP responses to spoofed queries, with those responses becoming fragmented because of their size.
