It's not uncommon for guest/visitor/unsponsored/portal wireless to
only have ports 80 and 443 (sometimes only port 80) open. You can
modify your server's config to use port 80 instead of 1194 (assuming
you aren't running a webserver on that machine). Keep in mind that if
you do that then before you can connect you'll have to:

o change the config on the server
o restart openvpn on the server
o change the config on the client
