[stunnel-users] Error resolving '...' (Windows)

[Oliver Ackermann (infowing AG)]

On a Windows 2000 machine I always get the following error when I try to

start stunnel (4.11):
Error resolving 'x.y.z.23': Neither nodename nor servname known
(EAI_NONAME)

The client should connect to a server using SSL. x.y.z.23 is a static IP

address of the client. The client has multiple IP addresses and stunnel 
should use this one to connect to the server.

Contents of stunnel.conf:
client=yes
[service]
local=x.y.z.23
accept=12345
connect=server:12345

Why does stunnel try to "resolve" this IP? Is the configuration correct?

Thanks for your help!
