OpenVPN - Can not ping second Node trough VPN

[volrath87]

Hello,

i have two firewalls (fw01 and fw02)

FW01 (172.16.3.5) is connected over crossover with FW02(172.16.3.6)
Both can ping each other.

On FW02 i have a openVPN Server. When i connect to FW02 with my client i can reach 172.16.3.6 but not FW01 and i dont get the issue.

For now i ve allowed any traffic via rule. But still not working.

Do you have any advice for me? (s. screenshots)
