[stunnel-users] running on one machine stunnel server AND client

Hi, I am using stunnel4 (stunnel 4.09 on i386-pc-linux-gnu PTHREAD+POLL+IPv6+LIBWRAP with OpenSSL 0.9.7e 25 Oct 2004) on debian linux. I want to run on one machine an stunnel server and an stunnel client, so it can recive a connection and also open a new connection to a different server (in the ascii graphic below server b) SERVER A SERVER B SERVER C | | | | ------>------ ----->---- The configuration file only allows me to specify client=yes or no, but I can not specify this for each connection. How can I set up a client and server on the same machine? Thanks Dan
