Thank you for a guide link. I manage to bring up tunnel with openswan too
004 "test" #4: STATE_QUICK_I2: sent QI2, IPsec SA established tunnel.
Unlike the IPSec tools openswan don't add a route to other side so i add manualy
route add -host 10.30.14.18 gw <My extenal IP>
but still get conection refused when trying to access other side service. Can't do much more today, so i'll wait till monday and contact other side administrator and get some info which of their acl-s block my traffic.
