This constructor always starts the tunnel (ignoring the i2cp.delayOpen option). It is used to add a client to an existing socket manager.

Parameters:
localPort - if 0, use any port, get actual port selected with getLocalPort()
sktMgr - the existing socket manager
Throws:
IllegalArgumentException

Parameters:
localPort - if 0, use any port, get actual port selected with getLocalPort()
Throws:
IllegalArgumentException - if the I2CP configuration is b0rked so badly that we can't create a socketManager
