Change both of these lines:
Code:
<address>Sitonmylap.dyndns.org</address>
<localaddress>192.168.0.105</localaddress>
...to your real external ip.
All machines behind your router should connect directly to your server by using your 192.168.0.105 in the eqhost text file.
I'm using a dynamic IP too but it's being controlled at the router level and not assigned within the server config files...at least, this is how it works for me for external and internal clients.
