Hello....I hope this is not too off-topic. I just purchased a WRT54G. Unlike my old wired Linksys router, this one does not have a way to configure "uPnP Forwarding". This feature changes an incoming request from the internet on a specific port to a different port behind the router on a specific IP address. Great for those of us who need to change standard service ports because incoming requests on those ports are blocked by our ISP's. Unfortunately, I will have to return my WRT54G if there is no way to do this. Oh yes, the router is also a V4....why do I think I'm SOL??? Thanks.
