Currently it does not have UPnP and also you have to setup all firewall related feature manually. I will try to incorporate them in my next release.
I recently installed the WNDR3800 OpenWRT beta on my router, and I'm happy to report it seems to be working well. Throughput is nice and strong so far, with no drops and good wireless signal.
I know it's an early build, and as such there aren't many features to mess with. I am wondering, though--what kind of security/firewall, if any, is built in to this firmware?
Also, does it have uPnP, or would I have to set up all port forwards manually?
