I just read '298 and it is NAT. It even use the words address translation in the text, describe the use with TCP, UDP and ICMP. However, it makes no reference to RFC 1631 despite the fact that it was released in 2004 (2 years before the patent was filled). Read claim 1:

A method of interfacing private and public data communications networks, through a filter node in communication with both networks, the filter node having an address known in the public network, comprising the steps of:

• routing from nodes in the private network, to the filter node, outgoing data packets having destination information, which includes a destination address and a destination port, corresponding to nodes in the public network and having source information, which includes a source address and a source port, of the respective private network nodes;

I'd say that this patent is a product of stupid end-of-the-ninety's management.

• "Hey, boss, I found that, could be handy."
• "Is it patented?"
• "No, I don't think so. It's an internet draft st..."
• "That new thing? I believe we own it. Write the patent".

Every single router vendor (including ISPs that propose their own routers) should be able to file a an amicus brief. Not to mention that the prior art is visible as hell here. NAT has been invented even before it has been RFC'ed.
