Village Idiot™ wroteOne curious thing I noted is that when pinging the domain name, it pings to a 10.x.x.x IP address which is not similar to the IP address assigned by the ISP. Is this the OpenVPN assigned IP?
10.x.x.x IP addresses are reserved private IP addresses as per
RFC1918 (See
http://www.duckduckgo.com)
If your no-ip domain name is resolving to a 10.x.x.x address then you most likely have not setup DNS correctly.
Without your config files and logs this is just an assumption ...
