vsphere esx port forwarding on Windows

Suppose I want to have console view of my VMs from my Windows desktop, 
but server address is not in the same subnet as my windows desktop,
In my case, server address is 15.226.49.40:902(default console port)
but my windows ip address is 15.116.*.*, the firewall rules of the Esx
server prevent my connection.

Here are the steps to dig tunnel to bypass the firewall rules:
1. putty set up a new ssh session
15.226.49.40:22

2. Putty setting portforwarding
L902 15.226.49.40:902
L443 15.226.49.40:443
the reason for 443, is because vsphere use 443 port to let client to login


3. modify  etc\hosts file
C:Windows\System32\drivers\etc\hosts
Add line:
127.0.0.1 esx


Now open vsphere client:
open the address: esx
instead of the actual server 15.226.49.40

And now you can connect vm console freely.

Linux x86_64 Firefox or Chome

I am a firefox fan, have been using it ever since its initial release.

But have to admit firefox doesn't work well on x86_64 linux platform.
I have a HP workstation z600 which has 12core/12G memory, but firefox
failed to response to a lot of website in a timely manner.

Just tried chrome x86_64 on my desktop, much better, strongly recommend.
