 Subject:  Problem regarding OpenVpn on b9 version
 Date:  Wed, 3 Aug 2005 00:17:48 -0300
Hello All,

    I'm new to m0n0wall project but I think I have found a bug in
OpenVPN support (lastest beta version). I know most VPNs would run
using UDP but I can't use because it is blocked in my University
firewall. The thing is, whenever I turn TCP option on, it still
accepts connection on UDP port only. I've tested it, rebooting and
stuff, and even when I click TCP it only listens on UDP port.

nc -u 192.168.200.1 1976 -v (UDP Test)
cusco.mine.nu [192.168.200.1] 1976 (?) open

nc 192.168.200.1 1976 -v (TCP Test)
cusco.mine.nu [192.168.200.1] 1976 (?): connection refused

  The logs also tells me that it's waiting for UDP connections:

Aug 3 00:03:21 openvpn[319]: UDPv4 link local (bound): [undef]:1976 
Aug 3 00:03:21 openvpn[319]: UDPv4 link local (bound): [undef]:1976 
Aug 3 00:03:21 openvpn[319]: UDPv4 link remote: [undef] 
Aug 3 00:03:21 openvpn[319]: UDPv4 link remote: [undef] 

Guess it's something pretty simple regarding the config file parser.

Thanks

Fernando Costa
