Do it with a hardware encrypted end to end VPN connected to that other
webservers switch with any port you want and sniffing will not matter plus
you then control the path.

Well, Management is asking whether, in this scenario; How secure will be the
traffic? They are asking the probability of data being sniffed.
The problem is that i do not have much info regarding the application.

Hi Kartik,

I think it is hard to tell what the risk is without knowing the 
application that will be making the connection. That's where the risk
might be.

Recently I got a change request which is to be implemented on the 
firewall. The requirement is to allow port 3270 from inside network to 
a webserver located in the outside world.
I would like to know the Risk/Threats associated with this change. I 
dont know what kind of a data would traverse in this setup but most 
likely its going to be something related with financial transactions.

Thanx & Regards
Sr. Specialist- Security
