Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.
From my understanding,
- You have a VM in Azure acting as Firewall (NVA)
- One in Israel, One in Europe
- You have a VM acting LDAP server in East Asia
- Connection between the NVAVmIsrael and LDAPserverEastAsia is working fine
- However, Connection between the NVAVmEurope and LDAPserverEastAsia is not working.
I suggested to check
- Is the VNET of NVAVmEurope and LDAPserverEastAsia peered?
- Test the connectivity:
- Using ICMP Ping or TCP Ping
Meanwhile, you informed us, you whitelisted the FW IP the connection started working.
Thanks,
Kapil
