Allow ping for proxy arp ip address

[Ugur_Urel]

Hi all,

Our firewall has several public ip addresses on external interface using proxy arp. Lets assume these public addresses are from 192.168.1.0 network.

Following ip addresses are assigned to interfaces directly;

• 192.168.1.1 (node1)
• 192.168.1.2 (node2)
• 192.168.1.3 (cluster ip)

192.168.1.4 and 192.168.1.5 assigned using proxy arp.

I would like to allow ping the ip address 192.168.1.4 from internet. I have defined a rule for 192.168.1.4 with icmp echo-request, I can see in the logs that traffic accepted but I can not ping from internet. Also if I add 192.168.1.3(cluster ip) to this rule, I can ping 192.168.1.3 from internet. 

How can I allow this traffic? By the way "Merge manual proxy arp configuration" option in the global properties is checked.
