We have two locations which are both production plants.

IP of Location A:
IP of Location B:

SAP HANA is also located at location B.

Location A is pinging many devices in location B, except HANA. (Operating system on HANA: SLES 11 SP3)

I also would like to emphasize that, SAP HANA is actively working at location B and we have no issues with SAP which works smoothly. Only problem is ping

Additionally, we use IPsec VPN between these 2 locations.

Do you guys think that, operating system is closed for pinging ?

I would be grateful if I could hear your comments on this issue and thanks in advance for your prompt response
