I've the same topology working with no issues (SIP TCP natted client,
a proxy and OpenSIPS as presece-server behind it, using TCP between
client and proxy, and UDP between proxy and OpenSIPS). It just works,
but you need a keepalive system to mantain the TCP connection between
the client and the proxy.
Tipically it's done by the client who keeps it by sending a periodic
TCP message (not a SIP message but anything).

Where is your problem exactly? do you have issues to get the first
NOTFY after sending the initial SUBSCRIBE? or do the issues arise just
for subsequent notifications?
