What's a good router to use for site-site transfers?

[- PzY -]

This may sound stupid, but I can not find any system of connection sharing that does not utilize NAT, but it appears that others here imply that all that is necessary is a non-NAT based router (or form thereof).

Is there such a thing as a router that people can successfully use to site-site (FXP) transfer via port 21? I have a Linksys BEFSR41 right now and afaik it is not possible to fxp over port 21 with this router. Everything I have tried (and I have searched the forums a lot and asked for help elsewhere) has failed. I could post error logs/version info/etc, but because it's 425 errors I know it's because of the router. Is there a different router that could actually work for this?

I know this is a stupid question, but I'd prefer no stupid answers.

Thanks.

seems like you'll need a router that doesn't handle NAT for ftp connections..or at least has an option to turn it off..
as for specific model i have no idea..
if people here won't be able to tell you, you could try www.dslreports.com hardware forum. they've seen many different routers so they might know..

maybe cheapest, simplest router that has absolutly basic NAT w/o "fancy" ftp screwup features is the way to go
