i’m pretty new to Mikrotik but now networking in general but i am having some difficulty with a setup at a customers place.
when i initially set it up i was able to have the sntp client function properly but after i completed the setup i am having difficulty.
we’re using an RB750g with ROS 5.0rc10 (yeah i know its not “final” i hope that’s not the prob)
i have 7 different lan subnets divided up among multiple small tenants and 1 shared voip pbx (on its own subnet)
there are 2 wan connections to different isp’s. 1 wan connection is pretty much dedicated to the largest tenant, the second wan is for everybody else & router generated traffic. i followed a guide on the website (can’t find the link jsut yet) but it showed how to setup a failover between multiple lan subnets and multiple wan links (with wan preferences) using mangle.
i setup the mangle rules as well as some basic firewall rules and now anybody using the RB750g for dns will not resolve. i am allowing requests on the dns settings and i even created “allow” rules for dns traffic from the lan side. i see the dns packets coming to the router from the lan and when i’m looking at the active connections i see the router going out to all the DNS servers attempting to resolve names, but the lan clients get no response back. i’ve tried everything with the firewall to no effect. SNTP doesn’t work either and the router thinks its 1970.
i’m imagining its the mangle & routing rules. i DID create an entry for traffic coming FROM the router to use the “main” routing plan and i have a standard default route without any routing marks. but the wierd thing is that i “see” the dns requests going out to the internet. i no longer see sntp going out at all however.
i would love to get this working without having to bother mikrotik support and i’m sure its probably something simple
thanks in advance, so far beside this little issue, i love routeros!
