If you would like help, here is a few things you will want to do in order to help us help you.

**Post your configs from client and server, without comments. you can strip comments in linux/bsd with something like this:
grep -vE '^#|^;|^$' server.conf
**Tell us your goal.
**If you are having problems connecting, post your logfiles from server and client after using verb 4 in both configs


Also, there are 2 things you should be aware of:

**Sometimes you cannot avoid tunneling over tcp, but if you can avoid it, DO. Why TCP Over TCP Is A Bad Idea: http://sites.inka.de/~bigred/devel/tcp-tcp.html
**You ONLY want to use dev tap if you are tunneling layer2 traffic, if you are using IP traffic you want tun. If you are using tap only for windows file sharing, look into running a WINS server instead.

can you verify that udp traffic is not filtered/altered on your server side?
