Yes and no. Depends on what you mean by VPN. VPN can be implemented in
many different ways. With IPSec implementation you may run into
problems (some solvable, some not). With user space daemon
implementations such as OpenVPN or VTun, you shouldn't have any
problems. Basically it is good idea not to have VPN endpoints behind
NAT (if possible, of course).
