vCenter 5.1 / vSphere 5.1 / firewall between :)

Dear all,

I am using two differents networks:

1- vCenter 5.1 + Windows server 2008 (from a different ISP)

2- vCenter appliance + ESXi 5.1 (network at home)

I would like to manage my ESXi server from the first vCenter .... Between them, there is my firewall.

For now three days, I am trying to make it working without any success ....

On my firewall, I have opened those ports:

TCP 31100

TCP 443

TCP/UDP 8000

TCP/UDP 8001

TCP/UDP 8100

TCP/UDP 902

UDP 427

UDP 6500

I am looking for information who can help me ...

Thx for your help.

Thierry
