We have configured 2 webservices(IIS & Apache) with different port and created service and define port range for the same than we configured NAT then follow with Security policy.

Now one webservice (IIS) is not from public network and other webservice (Apache) is working fine with the same Security Policy. 

Both are webservices are working fine in internal network.

Please help me to resolve the same

    Hi @sidhant,

    Thanks for your time today. After checking I have the below finding .

    1) Packets have reached to lan interface which means destination NAT works as expect.

    2) No handshake replies from a LAN server. But the IIS can be accessed by local lan.


    At this moment, looks like the issue are not related firewall. Please kindly check your IIS service and server.
