Hey Michael,
Well, I still haven't solved
https://forums.openvpn.net/topic9602.html. (According to
http://code.google.com/p/tunnelblick/wiki/QuickStartGuide#The_Set_Nameserver_Check_Box_and_DNS_and_WINS_Settings it might be fixable manually.)
Meaning that: at the moment I can only effectively work with a routed (tun) setup. That's why I ask it a bit more theoretically than normal because I still want to get the bridged (tap) working.
At my remote location, they use a proxy to block everything except HTTP/HTTPS and, depending on which of the two proxies I choose MSN
or Skype.
I want to receive my mail (some IMAPs and one POP3/SMTP account) in Apple Mail and maybe in the future some other things.
Therefor I need Apple Mail to connect via the OpenVPN server, like this I guess:
Apple Mail --- OpenVPN client tun/tap ---OpenVPN server tun/tap --- Mail host: ISP: POP3 @ 995 + SMTP @ 587 and Gmail: IMAP @ 993 and 465.
