SD-RED network can't reach XG Network

ValerioGabrielli

Hello everyone,
I have a problem with a sd-red 60 in transparent split mode, the scenario is:


- Tunnel is up and hosts behind red can surf.

- From XG I can ping the hosts behind the red and reach remote desktops and everything, but from Red I can't ping the
  hosts behind the XG.
-XG (virtual machine on ESXi) resides on a DMZ and is reachable from internet

Firewall rules:
LAN-ANY/RED-ANY
RED-ANY/LAN-ANY

Interfaces on XG:
INTERNAL 172.16.16.16
PUBLIC (dhcp): 192.168.0.185 ,gateway 192.168.0.1

RED  NETWORK 192.168.1.0/24

Any suggestion?

THANKS

    Hi  ValerioGabrielli 

    Please check the traffic flow under Packet Capture for not working traffic and drop packets from CLI will help you to find the firewall rule.

    Thanks and Regards
