Hi,

could you please try from CLI - ssh

ping source 172.16.20.100 host 192.168.1.1

ping source 172.16.20.100 host 8.8.8.8

Hi,

Traffic allowed in the firewall.But return packet is failing.Routing table also looking good. I think return packet not going to sub interface(eth1/1.10-172.16.20.100).so ping failed.

so what is the output of these 2 ping command ?
