Dear group,

I've to configure a couple of tunneled connections (call them TC1 and

TC2), client side, on a linux system.

The target of both such connections is the same (destination ip and port

are the same, call it DST).

At source side (my server) I have a two IP addresses (call them IP1 and

IP2) assigned and currently working to its unique NIC. I normally use

iptables SNAT to split the traffic between IP1 and IP2 depending on

destination addresses but in this case I've to distinguish it at

application level (TC1 and TC2).

I'd like to get TC1 to set the outgoing traffic with source address IP1 and

TC2 to set outgoing traffic with source address IP2.

    Tunnel          Tunnel

    Client          Server

TC1:  IP1    --\

                >-->  DST

TC2:  IP2    --/

I'm thinking to set one entry in stunnel.conf for each TC1 and TC2 and use

*transparent* = source  clause to set the source address but it seems my

case is not so common and I didn't find documentation.

Please could you suggest a solution.

Thanks
