Setting up a route

Question

I'm setting up a new F5 in Azure with the following IPs:

internal self IP: 172.20.0.100

external self IP: 172.20.068

Both of these interfaces are displaying as UP.

I have also created a quad zero default route:

Destination: 0.0.0.0

Netmask: 0.0.0.0

Resource : Use Gateway

Gateway Address: 172.20.0.93

I am trying to ping my DNS server (also included in my DNS Lookup Server List) at 172.20.0.105. It is pinging from my internal interface, and saying DESTINATION HOST UNREACHABLE. Telnet does not work (of course) and displays NO ROUTE TO HOST.

Is there something else I'm missing here?

Hi bcarreker,can you confirm your internal and external self IPs and netmasks ? As it is unclear why you define them in the same network if i read correctly.

Hmm strange...&nbsp;Just to make sure, just run :&nbsp;netstat -nr &nbsp;via SSH&nbsp;Then ping the default gateway, and run &nbsp;arp -an&nbsp;Might be something wrong at L2, but if so might be on azure's side ?Yoann
