Routing issue

RouterOS Forwarding Protocols
1

Good morning all.

I feel like a bit of a sap asking this but I have been struggling with a routing problem all night now.

I have / am in the process of updating my network to use OSPF instead of static routes as its become a little larger than initially anticipated. Since applying the changes:

I can traceroute from the internet boundary (CCR1072-1G-8S+) to the various client subsets

but get stuck when trying to traceroute the client to the internet boundary.

Looking for some advise to troubleshoot the problem.

youve given us almost 0 helpful information.

You know the last hop it fails at, jump on that hop check the route-table.

Is it that just ICMP is firewalled / blocked from that ingress point onwards?

Hi joegoldman,

Thank you for your response and apologies for the lack of info applied. As you suggested, I checked the last hop it failed at and instead of the OSPF config or the routing table the issue tuned out to be a faulty NAT rule that someone added to configure a camera from its default IP to a routed range and forgot to remove.

Thank you again.
