Hello,

I have recently had major issues with a very similar situation. in the end it was bad configuration on my part. things to make sure.

-- connect the two pc's using the normal network adapter in exactly the normal way you would network them (ie completely ignore the vpn at this point). Ping each computer and make sure there is normal comunication between each computer. Possible issues: You MUST have a cross-over network cable if you connect 2 computers directly (no hub) and you must have your network settings setup corectly (and NOT on the 10.3.0.x network as this is the network of your VPN)

-- Once this working correctly, do not touch the above network setup and startup your Opnvpn with a config file like:

remote [Tap Ip address of other computer OR netbios name of other computer]
dev tap
dev-node [name of your tap adapter]
ping 5
verb 5

This is a bare minimum you need to get this setup to work and ther is no encryption setup. I personally find that using netbios names works a little more relaibly than ip address (no good reason for this). The "verb 5" will give you R's and W's in the conenction window telling you what the adapters are doing to try and talk to each other.

Note: you MUST have the 2 dev lines which seem to be missing in your supplied configs. If you use this config above it should work. If it does then:

add in the secret key
Add in the compression
Change verb 5 to verb 3

And you should be fine to start the more advanced settings.
Good luck.
J
