How to get OpenVPN clients to use specified DNS servers

[jeffnoone]

I have multiple OpenVPN clients running simultaneously, including StrongVPN US site, and ibVPN US Site
Also have two ISP's temporarily at this point

I need the two OpenVPN services that are USA-bound to use specific DNS servers I have got from the companies - not the DNS servers off my ISP's.
I am assured by StrongVPN that "if I make this change, access to some US sites will recommence working"

How do I do this?
How do I tell what DNS servers these two OpenVPN clients are using right now?

Under "System" "General Setup", I have the DNS servers of my two ISP's
Is there some line I can put into the "Advanced Config" box of the OpenVPN client page?

Any help, or link to review, appreciated

Thanks
Jeff

To specify which DNS server you want used.  Go to System -> General Setup.  Then add your the DNS server you want used.
