I was checking the config (ttachmnet), I see the below:
set vrouter "untrust-vr"
set sibr-routing enable
set route 10.238.135.224/28 interface tunnel.2
set route 10.238.135.224/28 interface null metric 10
Are you trying to send the traffic to the VPN? is VPN up ?
What is the output of the get route ip 10.238.135.227 ? and the get route id <id number> ?
Thanks,
Vikas
