My routing table on my machine with IP of 46.84.121.243 currently looks like this -

Network Destination        Netmask          Gateway       Interface  Metric
          0.0.0.0          0.0.0.0     46.84.121.225     46.84.121.243     21
     46.84.121.224  255.255.255.224         On-link      46.84.121.243    276
     46.84.121.239  255.255.255.255         On-link      46.84.121.243     21
     46.84.121.243  255.255.255.255         On-link      46.84.121.243    276
     46.84.121.255  255.255.255.255         On-link      46.84.121.243    276

I'm trying to access 46.84.121.239, which is my other machine in the same DC but my guess is the first rule is blocking it as it is trying to go via the gateway and failing -

Tracing route to [46.84.121.239]
over a maximum of 30 hops:

  1  OWNEROR-9O83HBL [46.84.121.243]  reports: Destination host unreachable.

Trace complete.

I'm doing all this via RDP and already tried changing the metric on the persistent rule with devastating consequences! Here's the persistent rule (working) -

Persistent Routes:
  Network Address          Netmask  Gateway Address  Metric
          0.0.0.0          0.0.0.0     46.84.121.225       1

Any help to be able to access the 46.84.121.243 would be very helpful thanks very much.
